I swear I had one of these too, but it was in December, in Vegas, at the AWS con. (It started thurs or fri, was kinda pissed cause I booked some extra days in town but ended up staying in)

I don't remember all the symptoms, but I remember thinking how weird it felt and that "with a cold or the flu I usually get X"

Not gonna call it covid because I don't have any proof, but a "weird cold" is definitely going around
