DD was sent home today, as there's been a positive case in her class, with a letter saying she has to isolate for 10 days, until the 21st Dec.
I dont understand, as obviously 10 days before 21st is 11th, so does this mean she was in contact with the child on the 11th and they've only just had a positive test?
I thought only people who had been in close contact within the last 48 hours had to self isolate? Obviously I'm going to stick to what school have said, but I just can't understand the dates etc.
