Have had a few symptoms in the last day or two which are not classed as classic by the NHS - sore throat/headache/nausea/diarrhoea. Went through symptom checker on NHS website and they don't advise testing. Could soldier on at school today at a push but what if it is covid?? What a mess this is. Teaching yesterday was just about manageable though thought I was going to be sick at one point! Stayed 1 - 2m from students but did walk to back of room a couple of times to check they were working. Masks in corridors. Not sure what to do. Any advice welcome. In all likelihood, it's a different virus. Should I just tell the office and see what they recommend?
