Caught Covid at an event on Saturday: dozens of attendees reporting going down with it. Partner and I have the same symptoms, including sore throats, runny noses, fever and wheeziness. Partner's first Covid test, taken on Monday morning, showed a strong, almost instant, positive result. Mine was negative. I've taken one every morning since then and I'm still showing negative.
It wouldn't matter except that I have another event scheduled for Sunday and don't want to pass it on. But if I haven't actually had Covid at all, what am I to do?
