It's not flu. I just assume anything respiratory I get from the office or when travelling is COVID and so far antigenic tests always confirmed it. I take flu vaccine shots once a year and didn't get flu since years. Same for COVID but they don't work, I still get it at least twice a year with bad symptoms
