There has been an outbreak of COVID in my DDs nursery where she works. 5 out of 7 of the staff have tested positive, one worker who has been vaccinated doesnt have it and my DD had to have 2 tests as the first was inconclusive and the 2nd negative. My DD still has to isolate until Monday. Today she has developed an ongoing cough, has a high temperature and has a sore throat, but due to having had 2 tests already last week she has receved an automated response saying she cant have another one. Does she therefore assume she cant have caught it 7 days after the last contact with her infected team (she has been at home since as its half term) and therefore can come out of isolation on Monday. She is a bit confused about whether it cant be COVID as she tested negative on Wednesday.
