A surge in footballers testing positive for Covid-19 gives an indication of how fast the virus is silently spreading in the UK, scientists warn.
Six months into the pandemic, top level sports players and club staff are practically the only group being regularly tested for Covid-19, regardless of whether they are showing symptoms.
The picture is replicated in Premiership rugby, where four players and one member of staff at three clubs tested positive for the virus this week.
In the past week West Ham, Manchester City, Leighton Orient, Grimsby and Stevenage were among the clubs where cases were confirmed - with some fixtures having to be scrapped.
