Volunteers will be deliberately infected with the coronavirus in first challenge trials

Healthy volunteers will be deliberately infected with the coronavirus to test the effectiveness of experimental coronavirus vaccines in London next year, in the world’s first human challenge trials for coronavirus. About 2000 people in the UK have volunteered to be given one of a number of experimental vaccines and then receive a dose of the coronavirus under controlled conditions. The volunteers have joined the trial, which is due to begin in January, through advocacy group 1Day Sooner. Earlier this year the group organised an open letter signed by prominent researchers including Nobel laureates, urging the US government to immediately prepare for human challenge trials. The researchers behind the trials, which are being funded by the UK government, told the Financial Times that the trials would play an important role in helping to identify the most promising vaccine candidates likely to move into clinical testing in early 2021.

There were 6178 new coronavirus cases recorded across the UK today, the highest daily total since 1 May. Scotland recorded 486 new coronavirus cases yesterday, the highest daily figure since its epidemic began, first minister Nicola Sturgeon told a briefing today. In the Scottish city of Dundee, 500 university students have been told to self-isolate due to a suspected outbreak in a halls of residence. Meanwhile, in England, more than a million pupils were absent from school last Thursday for reasons related to covid-19, according to the nation’s Department for Education. Yesterday, the Isle of Scilly off the coast of Cornwall in England recorded its first coronavirus cases since the start of the pandemic.

The UK’s prime minister Boris Johnson has urged people in England to follow new rules announced yesterday aimed at limiting the spread of the coronavirus, warning that the government could introduce further restrictions if people fail to adhere. “If people don’t follow the rules we have set out, then we must reserve the right to go further,” Johnson said during a televised address. However, some have questioned the logic behind the new rules. “Closing down restaurants and pubs earlier will do little to stave the spread for as long as multiple different households can interchangeably meet up,” David Strain at the University of Exeter said in a statement.

The official test and trace app for England and Wales will be launched tomorrow after being trialled in Newham in London and the Isle of Wight. It will be the second iteration of the app, after the first was abandoned because it struggled to detect iPhones. There are concerns about the lack of transparency around the new app, and the government has not yet demonstrated that it is effective and ready for mass rollout, the Health Foundation charity said in a statement today.

Germany’s contact tracing app, the Corona-Warn-App, has been used to transmit 1.2 million coronavirus test results from laboratories to users during its first 100 days, according to officials. The app has been downloaded more than 18 million times since it was first launched in June and more than 90 per cent of laboratories in the country are now connected to it.

New restrictions for England could last six months, UK prime minister says

People in England will be asked to work from home where possible and pubs, bars and restaurants will be required to close at 10 pm each night, under a series of new restrictions announced by UK prime minister Boris Johnson today, which come into force on Thursday. Under the new rules, which Johnson today told MPs could stay in place for six months, pubs, bars and restaurants will be restricted to table service only and face masks will be compulsory for hospitality staff and non-seated customers, as well as for retail workers and taxi drivers. In Scotland, a ban on meeting people in houses will be extended from Glasgow and its surroundings to the entire country, and bars, pubs and restaurants will have to close at 10 pm.

Linda Bauld at the University of Edinburgh said in a statement that the new measures for England are not as stringent as might have been expected, with some of them already in place in parts of the nation under local lockdowns. “What is worrying, however, is that they will be accompanied by sticks but no carrots,” said Bauld, which she says “risks rising levels of non-compliance” among the public. Shops and hospitality businesses that fail to comply to the rules on use of face coverings, contact tracing and limits on maximum group sizes, risk closure or fines of up to £10,000. Fines for individuals not wearing face coverings or following rules will be increased from £100 to £200 for the first offence.

Cabinet office minister Michael Gove told BBC Radio 4’s Today programme that people should work from home “if you can,” a reversal of advice from the prime minister in July, when he encouraged people to go back to workplaces.

“The urging of people to work from home if at all possible is sensible. There should never have been encouragement of people to return to their workplace,” Michael Head at the University of Southampton said in a statement. “We have already seen outbreaks linked to the office environment, and there is no reason to promote an increase in numbers of commuters travelling on public transport.”

Other coronavirus news

The US Centers for Disease Control and Prevention (CDC) has backtracked on advice it posted last week regarding airborne transmission of the coronavirus. The advice suggested the virus spreads through tiny droplets that can linger in the air. The World Health Organization acknowledges that there is some evidence that airborne transmission can occur in crowded spaces with inadequate ventilation but says the main route of coronavirus transmission is through larger droplets from coughs and sneezes, which can land on surfaces and get onto people’s hands. The CDC retracted its guidance yesterday, with a spokesperson telling CNN that a “draft version of proposed changes to these recommendations was posted in error.”

More than 200,000 people in the US have now died from covid-19, according to Johns Hopkins University, the highest number for any nation. The country has recorded more than 6.8 million cases of the coronavirus.

Covid-19 was a factor in 1 per cent of all deaths registered across England and Wales in the week ending 11 September, according to the Office for National Statistics. The figure is among the lowest since March but there are concerns deaths may rise due to recent increases in cases and hospitalisations.

No new locally acquired coronavirus infections were recorded in New South Wales in Australia today for the first time in 76 days. Two infections confirmed yesterday were both returned travellers in hotel quarantine, according to local health authorities.

New localised lockdown restrictions to come into force in parts of the UK tomorrow

Amid warnings from scientists that the UK’s epidemic is doubling every seven days, which could lead to 50,000 cases a day by mid-October, the UK has imposed new restrictions to try and limit the spread of coronavirus. The country’s chief medical officers also advised that the coronavirus alert level be raised from 3 to 4. According to the government’s 5-tier alert system, an alert level of 4 indicates that transmission is high or rising exponentially and warrants increased social distancing measures. The UK is currently recording around 3000 cases per day, compared to around 5000 a day at the peak of the epidemic in spring.

Wales has now followed England in introducing additional localised coronavirus restrictions, set to come into force tomorrow. In total, at least 13.9 million people in the UK now face some form of additional local restrictions. From 6 pm tomorrow, people in Merthyr Tydfil, Bridgend, Blaenau Gwent and Newport in Wales will not be allowed to leave those areas or to meet with people from other households. Restaurants, bars and pubs will be required to close from 11 pm each night. Similar restrictions will affect Rhondda Cynon Taf in Wales as well as 10.9 million people in parts of north-west England, West Yorkshire and the Midlands starting tomorrow. Today, Scotland’s first minister Nicola Sturgeon told journalists that additional lockdown restrictions will “almost certainly” be put in place in Scotland over the next few days as well.

UK government considering short-term national lockdown in October

The UK could face a second nation-wide lockdown in October, according UK health minister Matt Hancock. In an interview today, Hancock told Sky News that the government isn’t ruling out a short-term national lockdown in October. “We do have to recognise that the number of cases is rising and we do have to act,” he said. This comes after warnings from senior scientific advisors to the government that the UK is about six weeks behind France and Spain in terms of coronavirus cases, and can expect to see a significant increase in cases by mid-October without further intervention. France set a record for daily new coronavirus cases in the country on Thursday, recording 10,593 new cases within 24 hours, according to its health ministry.

The latest estimate of the UK’s R number – the number of people each coronavirus case infects – is between 1.1 and 1.4, up from between 1 and 1.2 the previous week and between 0.9 and 1.1 the week before, according to the latest government figures. The current number is representative of the situation two to three weeks ago due to a time-lag in the data used to model the R number. In documents released today, the government’s Scientific Advisory Group for Emergencies warn that new infections in the UK may be doubling as quickly as every seven days and, according to the latest results from a random swab testing survey by the Office for National Statistics, about one in 900 people in communities in England had the virus in the week ending 10 September, up from about one in 1400 the previous week.

Parts of north-west England, West Yorkshire and the Midlands have become the latest areas in the UK to see tightening coronavirus restrictions. Starting on Tuesday, people in these areas won’t be allowed to mix with people from other households, and pubs and restaurants will be required to shut at 10 pm each day. “It does seem ironic that after encouraging mass attendance at pubs, cafes and restaurants through ‘eat out to help out’, that we are now contemplating restricting or closing those activities down,” said Jonathan Ball at the University of Nottingham in a statement. At least 13.5 million people in the country are now facing local restrictions of some kind, including 10.9 million people in England.

Steep rise in new coronavirus cases in England despite testing shortage

The weekly number of people testing positive for the coronavirus in England has risen sharply, as the country is experiencing testing shortages. Between 3 and 9 September, 18,371 people were diagnosed with covid-19, which is “a substantial increase of 167 per cent compared to the end of August,” according to NHS Test and Trace. These may be “the last reliable figures” on the state of the nation’s epidemic for some time because of the reduced availability of tests, said Daniel Lawson at the University of Bristol in a statement.

The time for tests to be returned is also taking longer. The proportion of test results received within 24 hours fell to 14.3 per cent during the same period in September, down from 32 per cent the week before. “Tests which take many days to report and action, are of no value in suppressing the pandemic,” said James Naismith at the University of Oxford in a statement. In June, UK prime minister Boris Johnson told parliament that all coronavirus tests would be returned within 24 hours by the end of the month.

The website for booking coronavirus tests online in the UK is struggling to cope with the growing demand for tests. An increasing number of users are reporting receiving error messages when attempting to book tests on the site.

Today the UK government announced new restrictions affecting almost two million people in the north-east of England, where case rates are particularly high. Under the new rules, which come into force at midnight tonight, people will be banned from meeting people from other households. Restaurants, bars and pubs will also be required to close at 10 pm. Affected areas include Sunderland, where the infection rate is currently 103 per 100,000 people, as well as Newcastle, South Tyneside and Gateshead, all of which have infection rates above 70, UK health minister Matt Hancock told MPs today. “The data says that we must act now,” said Hancock.

Europe has “alarming rates of transmission”, the World Health Organization (WHO) warned today, as it encouraged countries to stick to the recommended 14-day self-isolation period for people who may have been exposed to the coronavirus. In the UK, the recommendation is currently 10 days. Other European countries, including Portugal and Croatia, are considering reducing the length of recommended self-isolation, according to the Guardian. “Knowing the immense individual and societal impact even a slight reduction in the length of quarantine can have […] I encourage countries of the region to make scientific due process with their experts and explore safe reduction options,” Hans Kluge, WHO regional director for Europe, said at a press conference.

It will take at least a year before a coronavirus vaccine becomes generally available to the US public, director of the US Centers for Disease Control and Prevention, Robert Redfield told a US Senate panel yesterday.

Widespread reports of people struggling to get coronavirus tests in England

England’s coronavirus testing system is significantly overwhelmed, with many people in the nation’s 10 worst-hit coronavirus hotspots unable to get tests. People trying to book swab tests on Monday in Bolton, Salford, Bradford, Blackburn, Oldham, Preston, Pendle, Rochdale, Tameside and Manchester were told that it was not possible, according to LBC. Bolton currently has 171 coronavirus cases per 100,000 people, the highest rate in England. “It seems that there are several bottlenecks in the testing procedures. These are not being made publicly available so we can only speculate that these may be limited materials for the testing process, capacity and procedural issues,” said Brendan Wren at the London School of Hygiene and Tropical Medicine in a statement. “This needs to be addressed urgently, and if it is [a lab] capacity [problem] then university labs should be more widely deployed,” said Wren.

A spokesperson for the Department for Health and Social Care told the Guardian: “It is wrong to say testing is not available in these areas, and our capacity continues to be targeted where it is needed most.” However, there have also been reports of testing shortages elsewhere. NHS Providers, a body that represents hospital trusts in England, told the BBC that NHS staff are having to self-isolate, because they are unable to get tests for themselves or their family members.

Laboratories analysing community swab tests in England were stretched to capacity as far back as August, emails seen by the Guardian revealed today. NHS England sent an email to all NHS laboratories on 24 August calling for them to support the UK Lighthouse Labs Network, a private group of labs that has been analysing community swabs, due to a “surge in capacity.”

A report by the Bill & Melinda Gates Foundation warns that the coronavirus pandemic has pushed back progress on improving health around the world by “about 25 years.” The pandemic has increased poverty by 7 per cent and led to a drop in routine vaccination coverage from 84 per cent last year down to 70 per cent, according to the report. “It’s a huge setback,” Bill Gates said at a media briefing on the report’s findings today. The report also highlighted the disproportionate impact of the pandemic on women, racial and ethnic minority communities and people living in extreme poverty.

Schools in England have seen a higher absence rate among pupils this term compared to last year, according to the nation’s Department for Education. Official figures suggest 88 per cent of pupils attended school last Thursday, below the figure for the same term last year of about 95 per cent. Since schools reopened earlier this month, school leaders have warned that delays in testing are leading to year groups being sent home, the BBC reported.

New global record for daily new coronavirus cases as WHO warns of rise in deaths in Europe

A record single day increase in global coronavirus cases was recorded on Sunday with 307,930 new confirmed cases . The largest increases were in India, the US and Brazil, according to the World Health Organization (WHO). The WHO also warned that Europe can expect to see more deaths from covid-19 as soon as next month. “It’s going to get tougher. In October, November, we are going to see more mortality,” said Hans Kluge, WHO regional director for Europe, in an interview with the AFP news agency today. Cases in Europe have increased sharply over the last few weeks, with case rates highest in Spain and France. There are 270.7 cases per 100,000 people in Spain and 153.9 per 100,000 people in France, according to the latest 14-day cumulative figures from the European Centre for Disease Prevention and Control. In the UK there are 51.1 cases per 100,000 people.

Laboratory-made antibodies will be given to about 2000 covid-19 patients in UK hospitals as part of the UK’s RECOVERY trial, a large-scale clinical trial to test existing drugs as therapies for covid-19. In June, data from the RECOVERY trial provided the first evidence that a steroid drug called dexamethasone could save lives for those with severe covid-19. In the new trial of antibodies made specifically to combat the coronavirus, the first patients will be given the experimental treatment in the coming weeks. “There are lots of good reasons for thinking it might well be effective – stopping the virus from reproducing, stopping the virus from causing damage, improving survival for patients,” Martin Landray at the University of Oxford, who is co-leading the RECOVERY trial, told the BBC. “Monoclonal, or targeted, antibodies are already used to treat cancer and autoimmune diseases,” said Fiona Watt, executive chair of the Medical Research Council in the UK, in a statement. “The new trial will tell us whether antibodies that attack the virus can be an effective treatment for covid-19.”

An email seen by the BBC reveals that UK government chief scientific advisor Patrick Vallance argued that the UK’s coronavirus lockdown restrictions be imposed earlier than they actually were, and in response he was given a “telling off” from other senior officials. Vallance referred to advice given by the Scientific Advisory Group for Emergencies on 16 March, suggesting “additional social-distancing measures” be implemented “as soon as possible.” The UK went into lockdown on 23 March, about two months after the country’s first confirmed case, which some researchers blame for the UK’s high number of coronavirus deaths.

Israel has become the first country to announce a second nationwide lockdown to begin Friday and last three weeks. It is an effort to contain a second-wave surge of new cases, Israel’s prime minister Benjamin Netanyahu announced on Sunday. People will be required to stay within 500 metres of their homes, with the exception of travelling to workplaces. Schools will also be closed.

New data suggests England’s R number could be as high as 1.7

The UK’s coronavirus epidemic is growing, according to the latest government figures. Simon Clarke at the University of Reading described this as a “massive blow to the government’s strategy to contain the spread of covid-19.” The UK’s R number – the estimated number of people each infected person goes on to infect – is between 1 and 1.2, up from between 0.9 and 1.1 last week. This data is representative of the situation two to three weeks ago, due to a time-lag in the data used to model the R, but is in line with more recent data for England from a separate study by researchers at Imperial College London, which suggests England’s R number could be as high as 1.7.

The study, commissioned by the Department of Health and Social Care, tested over 150,000 people in communities in England between 22 August and 7 September and used this to model the R number. It found that 0.13 per cent of people tested positive – equivalent to 130 per 100,000 people in the population. The latest results from a random swab testing survey by the Office for National Statistics also indicate an increase in infections in communities in England and Wales in recent weeks.

The rise in cases “suggests that the recent uptick in cases is not just because of greater testing,” said Clarke in a statement. “It’s likely that the coronavirus is circulating more freely out in the community again, meaning we are likely to need greater restrictions on our lives to push the transmission rate back down again.”

A new coronavirus contact tracing app will go live across England and Wales on 24 September, the government announced today. The new app will allow people to scan QR codes to register visits to bars and restaurants and will use Apple and Google’s method for detecting other smartphones nearby.

Scotland’s app, Protect Scotland, went live yesterday.

Birmingham in England is being put under a local lockdown due to a spike in cases. The city now has the second highest rate of coronavirus infection in England, after Bolton.

Latest figures show significant jump in weekly coronavirus cases in England

The number of people who tested positive for the coronavirus in England was 9864 in the week ending 2 September, up 47 per cent from 6732 in the previous week, according to the latest figures from NHS Test and Trace. It’s the highest number of weekly positive cases recorded since the system was launched in May. During the same week, NHS Test and Trace only managed to reach 69.2 per cent of the contacts of people diagnosed with the virus in England – below the target of 80 per cent or more recommended by government scientific advisors to limit infections from spreading.

Public health specialists have raised concerns about the feasibility of government plans announced yesterday to spend £100 billion on expanding testing to 10 million tests per day by early 2021. Chaand Nagpaul, council chairman of the British Medical Association told the BBC it is unclear how these tests will work, given the “huge problems” with lab capacity. Sarah-Jane Marsh, director for testing at NHS Test and Trace apologised for the problems with the testing scheme earlier this week. Even if testing can be expanded, concerns remain about accuracy and contact tracing capacity. Transport secretary Grant Shapps told BBC Breakfast this morning that the technology to carry out the plan doesn’t currently exist.

US president Donald Trump admitted to playing down the threat posed by the coronavirus in March, during an interview with journalist Bob Woodward revealed in his forthcoming book. “I wanted to always play it down,” Trump told Woodward on 19 March. “I still like playing it down, because I don’t want to create a panic.” Trump also acknowledged the virus was “more deadly than even your strenuous flu” as early as February – a time when he was publicly saying the virus was less of a concern than the flu.

AstraZeneca chief executive Pascal Soriot today told an online briefing he is hopeful that the company’s coronavirus vaccine candidate could be ready for global distribution in the first half of 2021. Trials of the vaccine, which is being developed in partnership with the University of Oxford, were put on hold yesterday after a participant developed neurological symptoms. An independent safety committee is currently reviewing data on the affected participant, said Soriot.

Scotland’s Test and Protect system, the nation’s equivalent to NHS Test and Trace in England, today released its Protect Scotland app, which alerts people if they have been in close contact with someone who later tests positive for the coronavirus. Like Northern Ireland’s app, Scotland’s new app was built using the toolkit provided by Apple and Google. England doesn’t yet have a widely available equivalent app but has been testing a similar one on the Isle of Wight and in the London borough of Newham over the past month, after abandoning development of an NHS Covid-19 app built on different technology, due to its inability to recognise 96 per cent of Apple phones and 25 per cent of Google Android devices.

University students in England may be required to stay in their student accommodation and avoid visiting their family homes in the event of local coronavirus outbreaks, according to new guidance published by the UK Department for Education today. Students with covid-19 symptoms should “self-isolate in their current accommodation”, the guidance says. It also suggests that universities group students living in halls of residence into “households” that include all of those living on the same floor or sharing communal facilities, potentially including as many as 30 students. The guidelines add that private gatherings, including those within student households, must still be limited to a maximum of six people.

UK government plans to expand coronavirus testing to 10 million tests a day

The UK government plans to carry out 10 million coronavirus tests per day by early 2021, according to documents obtained by the BMJ. Currently, the UK’s testing capacity is 350,000 per day. As part of the new plan, £100 billion will go towards the expansion of the country’s testing programme, the documents revealed, and GSK and AstraZeneca are among firms named for supplying tests and laboratory capacity respectively.

Martin McKee at the London School of Hygiene and Tropical Medicine told the BMJ the plan is too optimistic and disregards “enormous problems with the existing testing and tracing programmes.” NHS Test and Trace in particular has been criticised for its repeated failure to reach a sufficient proportion of the contacts of people who test positive for the virus in England. Between 28 May and 26 August, the scheme reached 78.5 per cent of the contacts of people diagnosed in England – below the target of 80 per cent or more recommended by government scientific advisors.

Jon Meeks, a biostatistician at the University of Birmingham who reviewed the documents for the BMJ, tweeted that the documents “show a severe lack of science or reality. No consideration of harms that screening us all would create.” In the BMJ he raised the problem of false positives: “If you test 60 million people [with a 99% accurate test] we will be classifying a group the size of the population of Sheffield as wrongly having covid.”

Advanced trials of one of the most promising coronavirus vaccine candidates have been put on hold after a participant became ill in the UK. Drug firm AstraZeneca, which is developing the vaccine in partnership with the University of Oxford, has voluntarily paused the trials. This is standard procedure in vaccine development, and allows time for the researchers to determine the cause of the illness and ensure the safety of participants. AstraZeneca described the action as “routine” in a statement to STAT. The vaccine candidate has already passed preliminary trials, and is now undergoing phase II and III trials involving approximately 30,000 participants in the US as well as in the UK, Brazil and South Africa. These larger trials are designed to test whether it can prevent people from becoming infected with the coronavirus or getting ill with covid-19, as well as assessing long term safety.

Social gatherings in England will be limited to a maximum of six people from Monday 14 September, in an effort to tackle a recent spike in coronavirus cases. People will not be allowed to gather in groups larger than six either indoors or outdoors, with the exception of gatherings in schools, workplaces and some events such as weddings and funerals. UK health minister Matt Hancock told the BBC today that the new rule is “super simple” and will be “enforced by the police.” People could be fined between £100 and £3200 for violating the rule, he said. “We’ve seen in other countries around the world where they don’t take action then you end up with this second peak, resulting in more hospitalisations and more deaths, and we don’t want to see that here,” said Hancock.

New restrictions could be introduced across England due to surge in cases

The government could tighten restrictions on people meeting in England following the recent spike in coronavirus cases. According to several reports, the government could reduce the number of people allowed to meet outdoors to six, down from the current limit of 30. Restrictions on how many people can meet indoors may also become tighter, according to Sky News. Under current guidelines, only two households can congregate indoors.

England’s deputy chief medical officer, Jonathan Van-Tam, said the new wave of cases was because “people have relaxed too much.” Today, 2420 people tested positive for the coronavirus in the UK, down from 2948 on Monday but still high compared to daily figures in recent months. John Edmunds, a member of the Scientific Advisory Group for Emergencies told ITV that the UK as a whole is in a “risky period” because the country’s R number – the number of people each infected person goes on to infect – has risen above 1. An R number higher than 1 means that an epidemic is growing.

Some measures are already tightening in some parts of the UK, including Bolton, in Greater Manchester. The town currently has the highest case rate in the country, with 120 cases of the virus per 100,000 people. Pubs and restaurants there will now have to be take-away only and stay closed between 10 pm and 5 am, UK health minister Matt Hancock announced today. The current guidance, which says people should not socialise with those from a different household, will be made legally binding, he told MPs. The number of people allowed to visit hospitals and care homes will also be reduced under the new measures. “The rise in cases in Bolton is partly due to socialising by people in their 20s and 30s. We know this from contact tracing,” said Hancock, adding “we’ve identified a number of pubs at which the virus has spread significantly.”

Other coronavirus news

Amid increasing reports of people being told to attend drive-through testing centres hundreds of kilometres away from their homes, the director of testing for NHS Test and Trace, Sarah-Jane Marsh, tweeted an apology today to people in England who haven’t been able to get tested for the coronavirus. Marsh described laboratory processing as “the critical pinch-point” and said “we are doing all we can to expand quickly.” Last month researchers warned that the UK would probably face a second wave of coronavirus infections in winter if the country’s testing and contact tracing system didn’t improve by September.

There were 101 deaths from covid-19 in England and Wales during the week ending 28 August, according to the latest figures from the Office for National Statistics. This is down from 138 deaths in the previous week and is also the lowest number of deaths from the disease recorded since the week ending 13 March.

A school in Nottinghamshire in England has been forced to close after its head teacher was admitted to hospital with covid-19. Pupils and staff at Trowell Primary School have been told to stay home and self-isolate until 21 September. In the week since pupils returned to classrooms, coronavirus outbreaks have been reported at dozens of schools in England and Wales. Across Liverpool, an estimated 200 pupils are self-isolating after positive covid-19 cases at five schools, while five teachers at a school in Suffolk have tested positive.Coronavirus deaths

The UK recorded its highest number of daily new cases since May on Sunday

There were 2948 new coronavirus cases confirmed in the UK today, down slightly from the 2988 new cases confirmed on Sunday, which marked the highest daily increase in cases recorded in the country since 23 May. “This is especially concerning for a Sunday when report numbers are generally lower than most other days of the week,” said Paul Hunter at the University of East Anglia in a statement. “Sadly it is beginning to look like we are moving into a period of exponential growth in the UK epidemic and if so we can expect further increases over coming weeks,” said Hunter.

UK health minister Matt Hancock yesterday expressed concern about the rise in cases, which he said were largely among people under 25, especially those between 17 and 21. “Of course younger people can pass on the disease to their grandparents and we do not want to see that,” Hancock said yesterday. In France and Spain, rises in infections among younger adults in August were followed by higher numbers of hospital admissions for older and more vulnerable people in subsequent weeks. “It’s concerning because we’ve seen a rise in cases in France, in Spain, in some other countries across Europe, and nobody wants to see a second wave here,” Hancock said today.

Hancock’s concerns about younger people transmitting the virus to more vulnerable groups are shared by the government’s scientific advisors. A report endorsed by the Scientific Advisory Group for Emergencies published last week warns there is a significant risk that reopening universities could amplify local and national transmission, adding that “it is highly likely that there will be significant outbreaks.” Because of the higher proportion of asymptomatic cases among younger age groups, cases and outbreaks are also likely to be harder to detect among student populations, says the report.

Keeping schools safe: There is wide agreement that schools must reopen, and stay open. Achieving this is fraught with unknowns, however. Although it seems that children are less likely to transmit and get sick from the coronavirus, we don’t know why that is the case. Should an outbreak occur, pupils’ families and school staff could still be at risk. In order to keep schools safe, governments must be prepared to shut down other areas of society to keep overall levels of virus transmission low.

Russia’s vaccine candidate produced antibody and T-cell responses in early-stage trial

A preliminary trial of Russia’s coronavirus vaccine candidate Sputnik V suggests it is safe and induces an immune response. The vaccine was approved by Russian authorities last month, before any data had been made public or a large-scale trial had begun. In the preliminary trial, it was tested in a small group of 76 healthy volunteers. All the volunteers developed coronavirus-specific antibodies and T-cells, and none experienced serious adverse reactions, according to results published in The Lancet today. However, it still isn’t clear whether the vaccine protects people from becoming infected with the coronavirus or from getting ill. This will be investigated through phase III testing, which is already underway, and which is expected to include 40,000 people across Russia.

Some researchers are concerned that vaccine developers may come under political pressure to release doses of the vaccine for administration to the general public, before phase III testing is complete. “A vaccine should not be used to short-cut the implementation of public health interventions that are already known to be safe and effective, until the vaccine itself has been shown to be safe and effective,” said Eleanor Riley at the University of Edinburgh, in a statement.

The World Health Organization (WHO) today said it does not expect widespread coronavirus vaccination until mid-2021. “We are not expecting to see widespread vaccination until the middle of next year,” said WHO spokesperson Margaret Harris at a briefing in Geneva. Harris said phase III trials will need to go on long enough to determine how “truly protective” and safe a given vaccine candidate is.

Preliminary findings from a study by Public Health England found low rates of coronavirus infection among children and teachers in pre-school and primary school. Researchers took swabs from more than 12,000 children and teachers across 131 primary schools in England in June and early July, and detected only three cases of the virus. Ravindra Gupta at the University of Cambridge said the findings are not surprising, since limited numbers of children were attending schools in England during this time period. “We must not be complacent and falsely reassured,” said Gupta in a statement. “From September there will be more children, more mixing, more crowding and over winter less time will be spent outdoors,” he said, adding that there will be less chance to socially distance in schools in the coming months than it was possible to do in June.

New funding announced for trials of rapid new coronavirus tests in the UK

The UK government today announced £500 million worth of funding for trials of rapid coronavirus tests, including recently developed swab and saliva tests that can be performed in 90 minutes or less. The trials will also include community pilots investigating the effectiveness of repeat testing in schools and among the general population. “We are backing innovative new tests that are fast, accurate and easier to use and will maximise the impact and scale of testing, helping us to get back to a more normal way of life,” UK health minister Matt Hancock said in a statement today.

Having quicker tests could help speed up the identification of infected people and the tracing of their close contacts. But having a rapid test is “useless” if contacts can’t be identified because the tracing system is overwhelmed, Joshua Moon at the University of Sussex said in a statement. NHS Test and Trace has been criticised for its repeated failure to reach a sufficient proportion of the contacts of people who test positive for the coronavirus in England. According to the latest figures, 78.5 per cent of the contacts of people diagnosed with the virus in England were reached by NHS Test and Trace between 28 May and 26 August – below the target of 80 per cent or more recommended by government scientific advisors.

The US Centers for Disease Control and Prevention (CDC) has notified states to prepare for the roll-out of a coronavirus vaccine within two months. “Limited covid-19 vaccine doses may be available by early November 2020,” according to CDC documents first published by the New York Times. And in a letter to governors on 27 August, first obtained by McClatchy, CDC director Robert Redfield wrote: “CDC urgently requests your assistance in expediting applications for [vaccine] distribution facilities and, if necessary, asks that you consider waiving requirements that would prevent these facilities from becoming fully operational by November 1, 2020.” But public health researchers are concerned that the move is being driven less by evidence and instead by a political effort to rush a vaccine before the November election. Michael Osterholm at the University of Minnesota told the Associated Press that “the public health community wants a safe and effective vaccine as much as anybody […] but the data have to be clear and compelling.”

Pharmaceutical giants GlaxoSmithKline and Sanofi will start testing their protein-based coronavirus vaccine candidate in humans for the first time, to assess its safety and ability to induce an immune response. If this and subsequent trials are successful, the companies have said they could be requesting regulatory approval in the first half of next year.

A surge in demand for coronavirus tests has left the UK struggling to keep up. Some people with symptoms who tried to book coronavirus swab tests online told the BBC they were directed to testing centres more than 100 miles away from their homes. This could act as a “big disincentive to being tested”, Paul Hunter at the University of East Anglia told the BBC, potentially limiting efforts to contain localised spikes in cases.

Steroid drugs that reduce inflammation found to save lives from severe covid-19

A group of drugs that reduce inflammation have been confirmed to increase survival in people with severe covid-19. In a landmark study bringing together all the trials done so far looking at the effect of steroids on coronavirus, researchers in the World Health Organization (WHO) REACT working group analysed results from seven randomised clinical trials, which included 1703 critically ill patients with covid-19. They compared the outcomes of those who had received one of three corticosteroid drugs – dexamethasone, hydrocortisone or methylprednisolone – with those who received standard care or a placebo. The researchers found that 32 per cent of those who received a corticosteroid treatment had died from the disease after 28 days, compared to 40 per cent of those who did not.

“The evidence for benefit is strongest for dexamethasone,” Stephen Evans at the London School of Hygiene and Tropical Medicine said in a statement. These new results, published today in the Journal of the American Medical Association, add weight to earlier findings from the RECOVERY trial, which found that dexamethasone reduced deaths in critically ill covid-19 patients by a third for patients on ventilators and by a fifth for those receiving oxygen – the first drug shown to do so. “This analysis increases confidence that [dexamethasone] has a really worthwhile role in critically ill patients with covid-19,” Evans said. As a result of the study, the WHO is expected to update its guidance on treatment. In the UK, the drug has been in use for treating severely ill covid-19 patients since June.

The government today announced that restrictions on meetings between different households indoors in these areas, which were also due to be lifted today, would now remain in place due to increasing infection rates. Bolton currently has one of the highest rates of new virus cases in England, with 59 cases per 100,000 people in the week ending 29 August. Similar restrictions have also been introduced in the Glasgow area in Scotland, which has seen a rise in cases over the last two days.

Pupils around the world return to schools with new coronavirus measures in place

Millions of pupils returned to school today for the first time since coronavirus lockdowns were introduced, including pupils in France, Poland, Russia, England and Wales as well as in Wuhan in China, where the coronavirus was first detected. Schools in England and Wales have introduced hygiene and social distancing measures in line with recently updated government guidance, including wearing of face coverings by pupils in communal areas and staggering of break times for different year groups. But a survey of 653 parents in these regions by YouGov revealed that 17 per cent were considering keeping their children out of school due to concerns about coronavirus.

UK schools minister Nick Gibb today urged parents to send their children back to school. Doing so would “help them catch up on the lost education they’ll inevitably have suffered in the lockdown period,” he told the BBC Breakfast show. A survey of thousands of teachers by the National Foundation for Educational Research suggests that children in England are three months behind in their studies following lockdown, and that the estimated learning gap between advantaged and disadvantaged pupils has risen by 46 per cent. 98 per cent of the teachers in the survey, which was conducted at the end of the last school year in July, said their pupils were further behind in the curriculum than they should have been at the time.

Although there has been an increase in the use of face coverings in the UK, only 13 per cent of people who wear reusable face masks are maintaining them in a way that is helpful to stopping the spread of coronavirus, according to a poll of 1944 people by YouGov. The survey found that the use of face coverings in the UK increased from 38 per cent to 69 per cent from mid to late July. However, only 13 per cent of people who said they wear washable face masks also said they wash them after every use and at 60 degrees C or higher.

Children are at “strikingly low” risk of getting severely ill from coronavirus

Children are much less likely to get severe covid-19 than adults, and it is very rare for them to die from it, according to a UK study that was published in the BMJ today. The study tracked 651 under-18s admitted to hospital with coronavirus between January and July in England, Scotland and Wales. Six children died, 1 per cent of the total, and they had all had other severe illnesses before the virus struck, some of which were themselves life-limiting. The authors say this is a “strikingly low” death rate compared with 27 per cent for all ages in the population as a whole over the same time period. The findings are in line with previous similar research. Young people make up 1 to 2 per cent of cases of covid-19 worldwide, although it’s not clear why they seem to be less affected.

“There have been no deaths in otherwise healthy school-age children,” Calum Semple at the University of Liverpool told the BBC. “There is no direct harm from children going back to school,” he said. The findings come as some UK schools have been reopening for all their pupils for the first time since lockdown in March, with most schools in England due to be back by next week.

The UK has announced plans for quickly immunising large numbers of people if a coronavirus vaccine is developed before winter. They involve allowing a wider range of healthcare staff to give shots, such as midwives, physiotherapists and dentists, as well as pharmacists, who already administer flu vaccines. It also grants powers to approve any vaccine that is proven safe and effective before the end of the year to the Medicines Healthcare Regulatory Agency. This body will become responsible for approving all drugs and vaccines from the start of 2021 once the UK’s Brexit transition period is over.

Schools reopening in the US have found Legionnaires’ disease bacteria in their water supply, which can cause deadly pneumonia. The Legionella microbe was found in the water supply of five schools in Ohio and four in Pennsylvania last week, and experts say it could be in more.

The World Health Organization is trying to get more countries to join Covax, its coronavirus vaccine allocation scheme, according to documents seen by Reuters. The WHO plan would see countries pooling funds so that if one vaccine succeeds, all participants will get a fair allocation. But the UN agency has struggled to get enough richer nations on board. Countries including the UK, the US and Japan have made their own deals with manufacturers developing vaccines, securing millions of doses for their own citizens.

Several large US states have said they will not follow official federal policy to stop testing people who think they have been exposed to the coronavirus but who do not have symptoms. In a rebuke to the new testing policy announced by the US Centers for Disease Control and Prevention (CDC), California, Texas, Florida, New York and four other states have said they will continue with the old regime. The CDC’s move provoked claims that it was a politically motivated move to lower the number of people testing positive ahead of the 2020 election.

WHO warns Europe is entering “tricky moment” as coronavirus cases climb

As some European countries have continued to report growth in covid-19 cases, governments are responding by tightening up restrictions and safety measures. France reported 5429 daily cases today, up from 3776 a week ago, and Italy counted 1366 cases, its biggest daily increase in more than three months and up against 642 a week ago. Daily numbers in other major European countries are relatively stable, with Spain at 7296, Germany at 1507 and the UK at 1048.

The French prime minister Jean Castex warned the country had seen an “undeniable surge” of cases and the epidemic “could become exponential”, with cases rising as quickly as they did in the early days of the pandemic. The virus is now circulating in 20 of the country’s 101 “departments”, up from two previously. With France’s reproduction number – the average number of people one infected person will likely infect – now at 1.4, Castex said masks will become mandatory in Paris. The 21-day Tour de France will still go ahead this Saturday.

The German government today rejected calls to relax restrictions, with a leaked plan saying private parties will be limited to 25 people and the anticipated end of a ban on large public gatherings in October will instead be extended to the end of the year.

Hans Kluge at the World Health Organization said today that Europe is entering a “tricky moment” as schools reopen across the continent, though he stressed that schools had not been a “main contributor” to the epidemic. Asked by New Scientist at a press conference today if European countries’ responses to growing cases this week are commensurate with keeping the virus in check, Maria van Kerkhove at the WHO said: “What we are seeing is countries applying different measures. What we are seeing are targeted, tailored approaches. Hopefully these are time-bound.” On measures such as mandating face coverings and limiting the size of gatherings, she said: “All of these are different tools that may need to be applied. I think what we’re seeing is this calibration, of putting in efforts to suppress transmission to keep it at a low level while allowing societies to open up. This is one of the critical things we are all trying to figure out now.”

The number of patients getting heart disease services at hospitals in the US and UK dropped by more than half during the countries’ lockdown, researchers have found. Writing in the journal Open Heart, they warned cardiology departments need to be prepared for a “significant increase in workload” in the coming months as a result.

In the UK, government statistics today show that three months after the launch of England’s contact tracing scheme, it is still falling short of reaching 80 per cent of close contacts of people who have tested positive for covid-19, the level the government’s scientific advisers say is needed. Three quarters of close contacts were reached between 13-19 August. Nearly 300,000 people have been reached since the system’s launch.

Separately, anyone in the UK on a low income who needs to self-isolate for 10 days and cannot work from home will be eligible to get £13 a day from the government in areas affected by local outbreaks, health secretary Matt Hancock said today.

Face coverings will now be mandatory for secondary school pupils in areas of England under lockdown

Secondary school pupils in areas of England under local lockdowns will now be required to wear face coverings in all communal areas except classrooms, after the government reversed its guidance last night. The government has been under mounting pressure from headteachers to adopt a stricter policy on the use of face coverings ahead of schools reopening next month. Within coronavirus hotspots, “it probably does make sense in confined areas outside the classroom to use a face covering in the corridor and elsewhere,” UK prime minister Boris Johnson told journalists today, citing recently updated World Health Organization guidelines. The new rule won’t apply to schools in areas that aren’t under lockdown, although head teachers in any secondary school will have the flexibility to introduce their own rules. In Wales, the decision on the use of face coverings in schools will be left to individual schools and councils.

Other coronavirus news

The US Centers for Disease Control and Prevention (CDC) has been criticised for changing its guidelines on coronavirus testing to say that some people without symptoms may not require a test, even if they have been in contact with someone who tested positive for the virus. The change has not been explained by CDC leaders. Leana Wen, a doctor and public health professor at George Washington University, told CNN, “These are exactly the people who should be tested,” as they are key to contact tracing.

Fewer than 40,000 cases were confirmed in the US yesterday and daily new coronavirus cases there have been falling, after peaking on 22 July at about 70,000, though this may be due to insufficient testing. The total number of tests administered has fallen from an average of more than 820,000 per day in mid-August to about 690,000 per day in the last week or so.

UK government under pressure to review policy on face coverings in schools in England

There is growing pressure on the UK government to review its policy on the wearing of face coverings in schools in England, after the Scottish government today announced that secondary school pupils will have to wear them in communal areas from Monday. Public Health England’s current guidance, issued in July, doesn’t recommend the use of face coverings in schools. The Association of School and College Leaders – a headteachers’ union in the UK – has criticised the lack of clarity around the rules on whether teachers and pupils can wear face coverings in schools in England. “The guidance is silent on what schools should do if staff or pupils want to wear face coverings,” the union’s general secretary, Geoff Barton told the BBC. During a visit to the south-west of England today, UK prime minister Boris Johnson said the government is continuing to look at the changing medical evidence, adding “if we need to change the advice then of course we will.” The Welsh government has said it will review its position on face coverings in schools.

Earlier this month, the World Health Organization issued new guidance saying that children above age 12 should wear face masks in line with recommended practice for adults in the place where they live. Recent outbreaks in Scotland “reinforce the idea that covid-19 transmission in schools is potentially substantial”, said Rowland Kao at the University of Edinburgh in a statement. “Should masks be adopted, their use must be accompanied by awareness of the need for good mask hygiene and regular handwashing.”

Two more patients have been reported to have been reinfected with the coronavirus, one in the Netherlands and another in Belgium. Yesterday, researchers at the University of Hong Kong announced that they had documented the first case of coronavirus reinfection. “That someone would emerge with a reinfection, that doesn’t make me nervous,” Marion Koopmans at Erasmus University Medical Center in the Netherlands told Dutch broadcaster NOS. “We have to see whether this happens more often.”

Coronavirus cases in Spain are continuing to surge, with 175.7 cases per 100,000 people, according to the latest 14-day cumulative figures from the European Centre for Disease Prevention and Control. This is compared to 62.8 cases per 100,000 people in France and 22.5 cases per 100,000 people in the UK. Unions in Madrid last week warned that the primary care system was “on the edge of collapse” due to lack of staff and capacity for testing.

Less deadly in Europe: It is becoming increasingly clear that people are less likely to die if they get covid-19 now compared with earlier in the pandemic, at least in Europe, but the reasons why are still shrouded in uncertainty.

Plasma treatment: Blood plasma donated by people who have recovered from covid-19 will be used as a treatment for the infection in the US. The US Food and Drug Administration (FDA) granted an emergency use authorisation for the treatment on 23 August, but the evidence that it works is lacking.

First case of reinfection: A healthy 33-year-old man is the first person confirmed to have caught the coronavirus twice, according to unpublished research from the University of Hong Kong. As details of the case emerge, researchers say there is still much we don’t know.

Researchers say they have detected the first case of coronavirus reinfection

Researchers at the University of Hong Kong say they have documented the first case of a person being reinfected with the coronavirus. The team analysed virus samples taken from a man when he first tested positive for the coronavirus in late March, and again when he tested positive for a second time in mid-August. They discovered several differences in the sequences of the virus from the first and second infections, suggesting the man had been infected with two separate strains of the virus, rather than one long-lasting infection. Their findings have been accepted for publication in the Clinical Infectious Diseases journal.

What will the discovery mean for the dozens of vaccine candidates being developed to protect people against the coronavirus? It may indicate that being infected with the virus doesn’t necessarily protect people against future infections, said David Strain at the University of Exeter in a statement. “Vaccinations work by simulating infection to the body, thereby allowing the body to develop antibodies. If antibodies don’t provide lasting protection, we will need to revert to a strategy of viral near-elimination in order to return to a more normal life,” says Strain. But Brendan Wren at the London School of Hygiene and Tropical Medicine, said it is important to take these results into context: “This is a very rare example of reinfection and it should not negate the global drive to develop covid-19 vaccines.”

The US Food and Drug Administration (FDA) on Sunday issued emergency use authorisation for convalescent plasma as a treatment for severe covid-19. This is drawn from people who have recovered from infection with the coronavirus and contains antibodies to fight the virus. In a statement the FDA said that “the known and potential benefits of the [treatment] outweigh the known and potential risks.” More than 70,000 people in the US have received convalescent plasma as a treatment for covid-19 since March, through a programme run by the Mayo Clinic. FDA commissioner Stephen Hahn said studies have found a 35 per cent improvement in survival for covid-19 patients given the plasma.

At least 17 staff and pupils at a school in Dundee have tested positive for the coronavirus less than two weeks after pupils returned to schools in Scotland. Kingspark school closed last Wednesday and pupils have been told to self-isolate until 3 September. Scotland’s first minister Nicola Sturgeon today announced that secondary school pupils in Scotland may be advised to wear face coverings, in light of new guidance from the World Health Organization. Schools in England are due to reopen in September, but a spokesperson for the prime minister today said there are no plans to review the current guidance in England for the wearing of face coverings in schools.

Coronavirus R number in UK rises slightly but infections appear to be levelling off

In the UK, the latest estimate for the R number, the number of people each coronavirus case infects, has risen to between 0.9 and 1.1, up slightly from 0.8 to 1.0 the previous week. However, due to a time lag in the data used to model the R number, this is more representative of the situation two to three weeks ago. Estimates for the infection growth rates range between -3 and 1 per cent. This suggests infections in the UK are levelling off on average, in a continuation of the trend observed over the last few weeks. This is consistent with the latest results from the random swab testing survey by the Office for National Statistics, which suggests about 24,600 people in England – 1 in 2200 – had the virus in the week ending 13 August, compared to 28,300 people – 1 in 1900 – in the week ending 9 August

Local coronavirus restrictions in place in parts of northern England will be lifted on Saturday. People from two different households in Wigan in Greater Manchester and Rossendale and Darwen in Lancashire will now be allowed to meet in homes and gardens. But restrictions will remain in place in some other parts of Greater Manchester and Lancashire, as well as in parts of West Yorkshire and in Leicester. Oldham, which had the highest rate of infections in the UK last week at 103.1 cases per 100,000 people, has avoided the introduction of restrictions but will be subjected to “a more targeted intervention”, according to the Department of Health and Social Care.

Travellers arriving in the UK from Croatia, Austria and Trinidad and Tobago will be required to quarantine for two weeks upon arrival, starting at 4.00 am on Saturday, UK transport minister Grant Shapps announced yesterday. There are currently 47.2 cases per 100,000 people in Croatia compared to 21.2 per 100,000 people in the UK, according to cumulative figures for the last 14 days from the European Centre for Disease Prevention and Control. Those arriving in the UK from Portugal, which currently has a case rate of 28.5 per 100,000 people, will no longer need to self-isolate. Shapps said it would be “too difficult” for the UK to adopt a more targeted approach to the quarantine rules like Germany’s, affecting travellers from specific regions rather than entire countries, due to the difficulty in assessing infection patterns overseas in sufficient detail.

Coronavirus cases have been reported among pupils or teachers at 41 schools in Germany’s capital Berlin, less than two weeks after schools reopened. Berlin was one of the first places in Germany to reopen schools after the summer break. Schools in Scotland reopened earlier this month and schools in England will reopen in September.

South Korea recorded its highest number of daily new coronavirus cases since 8 March, with 324 new cases confirmed on Thursday. There have been 732 cases linked to the new outbreak so far, 56 of which have been linked to a single church in Seoul.

WHO warns of “risk of resurgence” in Europe as Germany and Spain see cases surge

The risk of a resurgence of the coronavirus “has never been far away,” the World Health Organization (WHO) regional director for Europe, Hans Kluge said during a briefing today. Europe recorded 40,000 more coronavirus cases in the first week of August, compared to the first week of June, when cases were at their lowest, and cases have steadily been rising in the region, in part due to the relaxation of public health and social measures, he said. Germany recorded its highest daily number of new cases since April, with 1707 new cases confirmed on Wednesday. Spain recorded 3715 cases on the same day, the highest daily number there since the country’s lockdown was lifted in late June. “Authorities have been easing some of the restrictions and people have been dropping their guard,” said Kluge.

Kluge thanked young people for the sacrifices they have made to protect themselves and others from covid-19 but expressed concern about people aged between 15 and 24, who account for a growing number of cases. “Low risk does not mean no risk. No one is invincible,” he said.

England saw a 27 per cent increase in the number of people testing positive for coronavirus in the week ending 12 August compared to the previous week, according to the Department of Health and Social Care. Its latest figures state that 6616 people tested positive for the virus, whilst the number of people tested for the virus went down by 2 per cent over the same time period.

UK health minister Matt Hancock yesterday told the BBC that people in the UK should be able to return to workplaces without the need for wearing face masks, citing evidence from NHS Test and Trace that people have been largely catching the virus in meetings between households rather than in offices. But researchers, including microbiologist Simon Clarke at the University of Reading, say there isn’t sufficient data to rule out the risk of transmission within workplaces and from workplaces to households. “The virus needs to be taken into homes by someone and they will have had to pick it up from somewhere else […] even a single workplace transmission could lead to multiple onward infections in a family, household or other setting.”

India reported a record daily increase in coronavirus cases for the country today, with more than 69,652 cases confirmed, according to its health ministry.

Random swab testing survey to be expanded in England and to other UK nations

Coronavirus tests will be carried out on more people in the UK to help monitor the spread of the virus, the government says. The random swab testing survey for coronavirus by the Office for National Statistics, which started in May, will be expanded to test more people in England as well as people in Scotland, Wales and Northern Ireland, the UK’s health minister Matt Hancock announced today. In England, the survey will expand from testing 28,000 people every two weeks in the community, outside of hospitals and care homes, to testing 150,000 people. Hancock said this is part of a wider effort to expand coronavirus testing in the UK.

Testing larger numbers of people will allow smaller changes in infection growth trends to be interpreted with more reliability, says biologist and medical innovation researcher Michael Hopkins at the University of Sussex. It will provide a “higher definition picture of the outbreak”, helping to pinpoint at-risk groups within the population, says Hopkins. More widespread testing could also help capture people who have the virus but are asymptomatic. An analysis by the ONS published yesterday found that only 28 per cent of people testing positive for the coronavirus in England reported having symptoms around the time they were tested.

Australia’s prime minister Scott Morrison backtracked today after saying that coronavirus vaccination would be mandatory in Australia. Currently there isn’t a coronavirus vaccine available but there are 160 vaccine candidates being developed and 31 are in human trials. The Australian government recently secured access to the vaccine candidate being developed by the University of Oxford in partnership with pharmaceutical company AstraZeneca, and has now said that if the vaccine is approved it will offer it to Australian citizens for free. Clarifying his earlier comments about making the vaccine mandatory, Morrison said “we can’t hold someone down and make them take it”, adding that vaccination would be “encouraged.”

Almost 1200 fewer people died this year in New Zealand up to 20 July compared to during the same period last year, a rare trend in light of the global pandemic. Some researchers speculate this may be due to a reduction in deaths from other respiratory illnesses, thanks to the introduction of measures to limit the spread of the coronavirus. In May, neighbouring Australia reported lower flu rates than usual, which was also attributed to coronavirus lockdown measures. New Zealand has recorded only 22 covid-19 related deaths.

South Korea recorded its biggest daily increase in coronavirus cases since March yesterday, with 297 cases of the virus confirmed. Officials in Seoul have begun introducing restrictions on gatherings in the city and its surrounding area, prohibiting indoor gatherings of more than 50 people and outdoor gatherings of more than 100 people.

Achieving herd immunity: Today, some headlines celebrate the fact that many places might have achieved herd immunity including Britain and pockets of London, New York and Mumbai. But others warn that millions will die before we get there. The true picture is far messier, partly because scientists don’t even agree on what herd immunity is, let alone how it might be achieved. So how will we know when populations are protected against the coronavirus?

“We need to prevent vaccine nationalism,” says WHO director-general

The World Health Organization (WHO) today called for an end to “vaccine nationalism”, the hoarding of vaccine doses by some nations. “The fastest way to end this pandemic and to reopen economies is to start by protecting the highest risk populations everywhere,” WHO director-general Tedros Adhanom Ghebreyesus told a press briefing today. “We need to prevent vaccine nationalism,” he said. The priority should be protecting essential workers and other at-risk groups, Ghebreyesus said: “If we can work together, we can ensure that all essential workers are protected and proven treatments like dexamethasone are available to those who need them.” Although there currently isn’t a vaccine available for covid-19 there are more than 160 candidates in development, with 31 in human trials. Several countries have already secured deals for doses of some of these vaccine candidates. The UK has purchased at least 190 million doses, including 100 million of the vaccine candidate being developed by the University of Oxford and pharmaceutical company AstraZeneca.

Separately, Takeshi Kasai, WHO Western Pacific regional director, told the briefing that “the epidemic is changing.” He said that “people in their 20s, 30s and 40s are increasingly driving the spread. Many are unaware they are infected.” This increases the risk of the virus spreading to the more vulnerable,” he added.

Public Health England will be replaced by a new public health agency, UK health minister Matt Hancock confirmed today. The new agency, called the National Institute for Health Protection, will combine “the expertise of Public Health England with the enormous response capabilities of NHS Test and Trace and the Joint Biosecurity Centre,” Hancock said at the Policy Exchange think tank. Dido Harding, the current head of NHS Test and Trace, will lead the new organisation initially, Hancock said. NHS Test and Trace has been criticised for repeatedly failing to reach the proportion of contacts of people diagnosed with coronavirus that is recommended by government scientific advisors – 80 per cent or more. Between 30 July and 5 August for instance, the system only managed to reach 74.2 per cent of the contacts of people who tested positive for the virus in England.

The proportion of people in the UK who reported experiencing symptoms of depression was 20 per cent in June, up from 10 per cent in July last year, according to a survey by the Office for National Statistics.
