Patients treated by two healthcare workers diagnosed with coronavirus in Brighton are being urgently tracked down by officials.

About a dozen patients are believed to have been in contact with the pair, who were working in general practice at the County Oak Medical Centre in Carden Hill.

One of them has been named as Dr Catriona Greenwood, who owns the French chalet with her husband where 11 people caught coronavirus from Steve Walsh, a businessman who contracted the virus in Singapore before flying to France then the UK.

The GP practice where Dr Greenwood works has been closed since Monday and a second branch - in the Deneway area of Brighton - was also closed on Tuesday for "urgent operational health and safety reasons".

Bevendean Primary School in Brighton has also said parents can choose to keep their children at home after a staff member had been in contact with someone who has been advised to self-isolate because they had been "in direct contact with the coronavirus".


The school remains open.

Dr Greenwood and her colleague were two of four new coronavirus cases in the UK confirmed on Monday, bringing the total to eight.

All four, and another case the day before, contracted the virus in France after coming into contact with Mr Walsh.

He was then diagnosed in Brighton on 6 February, making him the UK's third case, before being taken to the infectious diseases unit at St Thomas' hospital in London.

The 53-year-old businessman is linked to 11 cases, including the five in the UK and six Britons in France and Majorca, prompting fears he is a "superspreader".

Five Britons, including a nine-year-old boy, are in quarantine in France after contracting the virus in the ski resort of Les Contamines Montjoie from the man.

Jerome Salomon, head of France's national health agency, said 61 people including the boy's schoolmates were tested for the virus but all were negative.

World Health Organisation director general Tedros Adhanom Ghebreyesus said the new UK cases were "concerning instances of onward transmission from people with no travel history to China".

He warned such spread "could be the spark that becomes a bigger fire" as he urged countries to work to contain the virus "to prevent a bigger fire".

The director general said although 99% of cases are in China it "holds a very grave threat for the rest of the world".

Public Health England's medical director Yvonne Doyle said: "We are now working urgently to identify all patients and other healthcare workers who may have come into close contact, and at this stage we believe this to be a relatively small number."

The County Oak Medical Centre in Brighton's Carden Hill area also remained closed on Tuesday after people wearing haz mat suits were seen cleaning the surgery on Monday.

Professor Martin Marshall, chair of the Royal College of GPs, said it is "still more likely that anyone with flu-like symptoms will have the flu".

He said: "However, in light of the members of staff who tested positive for coronavirus in Brighton we'd like to remind the public that it is vital that any patient who thinks they may have symptoms does not try to attend a GP appointment or hospital emergency departments in person.

"They should stay at home and call NHS 111."

Coronavirus: The issue with face masks

On Monday, Health Secretary Matt Hancock declared the virus a "serious and imminent threat" to the British public.

The move gives health professionals legal powers to keep those in supported isolation against their will after one patient threatened to escape from Arrowe Park Hospital where some of those evacuated from Wuhan are being kept in isolation.
