I am a key worker (teacher) and therefore expected to be working on a rota. I had a sore throat and temperature of 38 on Saturday so I have self-isolated since then. I was monitoring symptoms for 7 days as advised and nothing more has come of it - I still have a mild sore throat but nothing else. So, should I continue isolating for another 7 days, totalling 14, or go to work on my rota day, which would be 11 days after the temperature?
