Anybody care to weigh in on something I can't figure out. Last October I had some sort of illness, with severe flu like symptoms.
However my nasal swab PCR test, taken 48 hours after symptoms, came back negative. I assumed it was flu, but everything I'm read suggests that flu is virtually unheard of this season. For a standard cold, it seemed to severe (102 F fever, body aches and chills). I also had a strong reaction to the first Covid vaccine dose. What's the most likely explanation here?
