Watford have confirmed three people at the club have tested positive for coronavirus after the Premier League announced six live cases across England's top flight. Burnley account for one of the other three.
One player -- Adrian Mariappa -- and two members of staff have contracted the virus at Watford and will now isolate at home for seven days before being tested again.
At Burnley, Sean Dyche's assistant manager Ian Woan is one of the other positive cases in the Premier League. The other two cases belong to a third club which has not been revealed.
In total, the Premier League carried out 748 tests on May 17 and 18 on players and staff at the 20 clubs. The results were published anonymously at first.
Watford's positive cases come after the team captain, Troy Deeney, refused to return to training citing concerns over his child's health, who at five months old has suffered breathing problems since being born.
The Premier League has been suspended since the middle of March but it hopes to return at some point in June, similarly to Spain's LaLiga.
