Scott Parker said on Friday that he does not know whether the game at Turf Moor will go ahead.
The whole squad has since been retested but Fulham will not know the results until Saturday morning.
Parker said: “I do not know whether the Burnley game will go ahead.
“Those who tested positive are in isolation. We had a number of positive tests.
“I do not know whether the Burnley game will be played or not. We have retesting over the last few days. We are preparing as best we can to go to Burnley and get some points.
“We travel up tomorrow and had testing today, results will come back on that morning so at the moment it is full steam ahead. The wellbeing of players is paramount.”
