One of those 2 likely existed, as our family got it. During that time the covid 19 “proper” was long gone, and the flu “was not around” according to the media. Whatever we got, it was nasty. Not the worst I’ve ever had, but still very unpleasant.
Yeah we had one or the other. The transition from Delta to Omicron was supposed to be happening here at the time and was definitely different than a cold or flu. No worse for us than a bad case of the flu but different.
After the past several years, especially the past few years, it’s just hard to know what to believe.
