Personally I’m curious about whether or not the discovery that covid mostly is airborne and not transmitted via fomites has led to any similar realizations about the flu and common colds, which people have forever been told can largely be avoided by washing your hands and not touching your face. Has it ever been true, about any respiratory illness?
I don’t get stomach bugs (ever. I have not in over 4 decades of life had even one bout so I may be one of the lucky few who are immune) so has all the handwashing I do been a waste of time? Just kidding, I have an aversion to dirty hands. But really, does washing your hands really keep you from getting a chest cold?
It feels like covid has been the most intensely studied human virus in decades, so has this led to other discoveries too, in addition to my own question above?
