Sorry if this has already been asked.
We have had outbreaks in several schools in our area, we are also on the government watch list. One of the schools have asked a whole year group to isolate for 2 weeks, while some of them have asked only the infected child or teacher to isolate, another has asked any 'close contacts' of the infected child to isolate.
They all say that advice was taken from PHE but I don't understand why there all so different. Does anyone know if there are actual rules related to this or is it just assessed case by case?
