Hi I’m devastated. I tested positive for covid yesterday. I’d had a cough for 3-4 days beforehand but was testing negative. I was meant to visit my terminally ill Nan on Monday who has been moved to a hospice but they are testing for covid prior to you entering so obviously want a negative result. I’m worried now I won’t get chance to say goodbye to her. How long do you test positive for? How often should I re test myself? My cough seems to have subsided but just a bit snotty and no sense of smell.
