How I know what I got-
A few extra trips to the bathroom - Flu.
Runny nose and snot is clear - Cold(if snot is yellow then allergies or sinus infection.)
If it's Covid. . .probably. . . treated it as either Flu or Cold.
HOW DO I KNOW IF I HAVE A COLD, THE FLU OR COVID-19? YOU TAKE A TEST THAT DOESN'T RELIABLY DIFFERENTIATE BETWEEN THE THREE, AND THAT KEEP GIVING FALSE POSITIVES . . . IF YOU CAN EVEN GET THE TEST. CHEERS. NOW THAT'S A FIRST WORLD PROBLEM.
