Watford manager Nigel Pearson has revealed two more of his players are in self-isolation after family members tested positive for coronavirus.
It follows defender Adrian Mariappa and two staff at the club receiving positive results in the Premier League's first round of testing.
"The testing situation is obviously to minimise risk, so for the players and staff who have been in this week statistically they should be a lot safer but it is still a surprise for those who have tested positive," Pearson revealed.
"They're all feeling OK, and likewise for their families as well. That is important for us to make sure that those people - their health is OK.
"In addition to that, we've had a couple more people who have to be in isolation because they've been in close contact with people who have tested positive, even though their own result came back negative.
"I think that shows the types of complications that we've got. Today everybody has been tested again, we were tested on Friday morning, and we await further results over the weekend now.
"It is just something we have got to get used to. We are trying, as everybody will be, to establish what is now a more normal working practice in the circumstances that we have. That is what we have got to work with. But they're OK."
Several of the Watford squad, including captain Troy Deeney, are staying away from training due to ongoing safety concerns.
