Hi, my colleague’s daughter is in nursery full time and one of the staff there (daughter’s key worker) has tested positive for COVID-19. The nursery have said that the daughter (who is 3) does need to self isolate for 14 days but my colleague doesn’t. Unless she becomes symptomatic or someone in the household develops symptoms. I am obviously terrified now - I am asthmatic and although not shielding I suppose it is an underlying condition. Any advice please?
