I can't say if I had it or not. In Jan, we had a garage sale Sat-Mon (MLK Day was a holiday, so we went all 3 days). At that point, Corona Virus was a "we don't know much" blip on the news, and just days from Trump halting travel from China.
With all the people coming and going to the sale, there's no telling what germs I may have come into contact with.
That Wednesday, the symptoms started. Felt like a cold or mild flu at first, then had heavy coughing from sinus drainage, sore throat, raspy breathing, fever, and runny nose. I never got the achiness I normally get with the flu, which was odd, considering how fatigued I was.
I basically had all the symptoms they now tell us could indicate COVID.
Took about a week to 10 days to no longer feel sick, and a few more days to feel normal. Went through lots of NyQuil Severe Cold and Flu med and others to break up the mucus in my lungs and suppress the cough.
Nobody else in the house ever caught it, so I think that might be a sign it was regular flu, given the reported communicability of COVID.
It's possible having the flu also helps prepare you for fighting COVID if you do get infected. Who knows?
