My son and daughters school has had a large outbreak of covid. Aprox 90 kids got sent home yesterday to isolate. Now his best friends mum just phoned to say her daughter has tested positive this morning. So my kids are isolating anyway but I was in contact with the friend I need to isolate too. We as a family are booked in for testing this morning. So this is what I don’t understand, if we are all tested and are negative do we still need to isolate. I haven’t had to deal with this yet.
