How long has it taken in your house to catch from another family member?
DD is positive, she is 5 so we are with each other all the time really other than when she is at school and when she is in bed (has own room). She was a bit tired on Sunday but LFT was negative, went to school on Monday (didn't test as didn't have any and she was fine again) and then on Tuesday we heard that half her class have Covid and so I tested her first thing and it came up immediately, very strong positive. So I assume she's been infectious since maybe Saturday or Sunday...when can we expect to be struck down? Nobody is boosted in the house but both double vaccinated. Other DC is too young for vaccine so I am mostly keeping them apart as she has already missed so much school.
