I swear I think I had it around the New Year.
I was sick with flu around February, and I hardly ever get flu, even though I also never take the flu vaccine.
Our kid was pretty ill Christmas Eve (although not extreme), and stayed the night with us. My wife was more ill than our kid late in December, and was still ill on January 3. Had residual symptoms for at least a week after. I can't be certain, but they might have had COVID-19.
