Maybe
But the list of symptoms associated with covid-19 keeps growing, to the point where it seems like anything even slightly out of the ordinary might be a sign of a coronavirus infection. In the first couple of months of the year, I had occasional blips of elevated temperature, sniffles, the occasional cough or sneeze, aches and pains, you name it. Only an antibody test can say for sure.
For a while, I took comfort in the thought that if I had a mild case, it might confer immunity at little or no cost. But now they (WHO, et al) aren't sure that immunity happens, so...now what?
