Sixteen have tested positive for COVID-19 in the English Premier League's latest round of tests carried out on 3,060 players and club staff.
The third round of tests conducted between August 16-22 showed an increase in infections after the English top flight recorded 20 cases in the first two weeks of testing.
Among the players who tested positive last week were Chelsea's Christian Pulisic and Arsenal's new signing Ben White, with both players missing Sunday's clash which Chelsea won 2-0 to move to the top of the standings.
Arsenal forwards Pierre-Emerick Aubameyang and Alexandre Lacazette were among club's four positives a week ago.
But Aubameyang returned to the side for the weekend's clash.
