I agree with SachaMac; I have COVID at the moment, confirmed by PCR after 2 negative lateral flow tests. Having been ultra cautious, went to an open air event where I and DH were among the very few wearing masks, no distancing, but outdoors. Double jabbed with positive anti-spike antibodies ( we are on the ONS programme). In the end, probably caught it from the friend we went with, who looks after her dgd several days a week, who had a “cold” on returning to school. Friend fell ill and tested positive before me.
As it stands, no worse than a bad cold at the moment; high temp, aches and pains, headache, cough, sweating a lot and lost taste. I have to quarantine for 10 days. But no way of predicting severity if you catch it. Would be inclined to be cautious if I were you. Wish I had followed my instincts and pulled out of going to the event, where nothing like an op depended being COVID free, but I didn’t want to let people down.
