Fourty positive coronavirus cases were discovered over two rounds of Premier League testing in late December and early January.
The league announced its latest figures on Tuesday afternoon which showed that of 1,311 players and club staff tested between 28 and 31 December, 28 came back positive for Covid-19.
In tests on 984 players and staff carried out between 1 and 3 January there were a further 12 positives, the league said.
It is understood the bulk of the positives relate to the three postponed fixtures over the period involving Manchester City and Fulham.
City’s match against Everton on 28 December was called off because of an outbreak at the Manchester club, while Fulham’s games against Tottenham and Burnley on 30 December and 3 January, respectively, have also had to be rescheduled.
All those who tested positive must self-isolate for 10 days.
It is understood the second round of testing featured a smaller group of players and staff than usual because it took place over a weekend, when some teams were involved in matches.
The Premier League said in a statement confirming the new figures: ‘With low numbers of positive tests across the overwhelming majority of clubs, the league continues to have confidence in its Covid-19 protocols, fully backed by the government, to enable fixtures to be played as scheduled.’
The league is understood to have held conversations with Culture Secretary Oliver Dowden following the announcement of a new national lockdown on Monday night, in which the minister expressed support for the measures being taken and gave his backing for elite sport to continue.
The PA news agency understands there are ongoing discussions between the clubs and the league about ways in which the protocols can be further tightened in communal areas like training grounds and any pre-match accommodation.
There have also been a number of incidents involving Premier League players breaching coronavirus rules which everyone in society is expected to abide by.
Tottenham trio Erik Lamela, Giovani Lo Celso and Sergio Reguilon were photographed at a gathering which was also attended by West Ham’s Manuel Lanzini.
Manchester City boss Pep Guardiola defended the club’s full back Benjamin Mendy after he breached restrictions by inviting friends to his house on New Year’s Eve.
‘It would be better if, before we judge others, we judge ourselves,’ the Catalan coach said.
In the National League, Dagenham’s match with Solihull on Saturday has been postponed because the entire Daggers squad and staff are isolating.
The club said that, although none of their players had tested positive for Covid-19, ‘a number of staff members’ had, necessitating the move.
