Covid. Confirmed.
Almost three years of beating the pandemic, go to ONE class for two hours, and catch it from some asshole who attended in spite of hacking and coughing almost continuously.
A roomful of retirees and Covid Jack decides to spray his diseased spew promiscuously.
Hope he’s in ICU by now.
I once had a cousin who died from that(yahoo boards.) LOL
People in my area have been pretty good about not coughing but I would always run into one at the market 
Hopefully what you have will be one of the weaker variants.
So far mild.
A couple retiree neighbors of mine just came back from a Med. Cruise compliments of their son who is on staff as a “Trainer” with Norwegian Cruise Lines…with covid, last I heard bad cold/flu symptoms, but not too serious.
