Postcodes surrounding Cheltenham racecourse have had the highest number of coronavirus hospital admissions after this year's annual festival went ahead.

More than 250,000 people attended the four-day event in Prestbury Park which took place between March 10 and March 13.

The decision to go ahead with the races was slammed by many after a number of celebrities who attended, including Andrew Parker-Bowles, comedian Lee Mack and footballer Charlie Austin, came down with the virus.

Leaked data shows that the GL52 postcode, which covers the area surrounding the racecourse, reported the highest number of coronavirus-related hospital admissions in Gloucestershire up to April 3.

The second highest area for COVID-19 hospital cases is GL51, which includes Cheltenham Spa Railway Station, used by many of the race fans attending the track.

The alarming data was leaked to the Local Democracy Reporting Service.

According to Gloucestershire Live, the two postcodes are responsible for a quarter of all COVID-19 admissions in the county.

In quotes: What's being said about whether Cheltenham should have gone ahead? Paul Hunter, professor in medicine at the University of East Anglia: 'Could the Cheltenham Festival have led to an acceleration of cases locally that has fuelled this local high mortality rate? This is certainly possible and in the absence of any other factors that I may not be aware of, is quite likely.' Professor John Ashton, a former director of public health for Cumbria: 'We know the Festival went ahead and a lot of people will have attended and worked there. It's important we learn about what the potential is for coronavirus transmission at public events.' Lawrence Young, a virologist and oncologist at Warwick Medical School: 'I don't think that allowing the Cheltenham Festival to go ahead was sensible but assume that the attendance was from far and wide, not just the locals.' Paul Hodgkinson, Gloucestershire council's Liberal Democrat group leader: 'Future investigations may well conclude that events such as this were at least partly responsible for a significant proportion of the UK's transmission, and the devastating consequences that we've seen as a nation.' Sarah Scott, Gloucestershire council's public health director, said: 'There are many factors that could influence the number of cases in an area, including population density, age and health profile and the position of an area on the pandemic curve.' Chancellor Rishi Sunak: 'At every stage in this crisis we've been guided by the scientific advice and have been making the right decision at the right time' Sue Smith, senior racecourse medical officer at Cheltenham Festival: 'It's simply not possible to know how and where someone who has tested positive for Covid-19 has contracted it'. Jockey Club: 'The festival went ahead under Government guidance to do so, like other sports events at Twickenham, Murrayfield, 10 Premier League matches and the UEFA Champions League, all with full houses that same week' British Horseracing Authority: 'The Government advice before and during Cheltenham was that mass gatherings were not a high area of risk, provided hygiene measures were in place and observed.'

The race festival was held 10 days before Prime Minister Boris Johnson announced the coronavirus lockdown and three days before the government recommended social distancing measures.

There was significant criticism of the decision to hold the meeting, which is the highlight of the National Hunt season because of the threat posed by the deadly bug.

Cheltenham Racecourse defended the festival claiming they had been following government guidelines at the time.

Organisers The Jockey Club told the local council that Prime Minister Boris Johnson's attendance at the England v Wales rugby match at Twickenham on March 7 was among the reasons they refused to cancel the races.

Gloucestershire has the highest reported rate of COVID-19 cases in the South West according to Public Health England.

Gloucestershire Hospitals NHS Trust has recorded 125 deaths from the disease so far, more than double those in nearby Swindon with 67, Bristol on 58 and Bath on 46.

This huge disparity is despite the four trusts having relatively similar emergency admission rates in the 2018 to 2019 period, ranging between 45,000 and 56,000.

As well as holding the Cheltenham Festival, the government was criticised for allowing the Liverpool v Athletico Madrid Champions League match take place on the week beginning March 9.

Thousands of fans from the Spanish capital flew to Merseyside for the game, despite the rapidly increasing number of Covid-19 cases in Spain.

The government was also prepared to allow the Premier League to continue matches into mid-March.

Football authorities decided to suspend the competition on March 13 after the Arsenal head coach Mikel Arteta and Cheslea striker Callum Hudson-Odoi contracted Covid-19.

Some 45 matches were due to take place in the Premier League and EFL ahead of the government's eventual lockdown decision.

Leading epidemiologist Dr Rowland Kao of the University of Edinbury.

He said the decision by football authorities to scrap matches over the weekend of March 13 could have saved lives.

He said: 'There's no guarantee with the number of infected people in the country at that time that somebody (with the infection) would have been there.

'But if someone had been there and been infectious, there was a potential for very large amounts of spread.

'The problem you have in making that comparison is there's no counterfactual. The people who got infected may have got infected anyway.

'But broadly speaking, the more things we would have done of that nature (banning mass gatherings), the better off we would be likely to have been.'
