@Linkat,
You dance real well, but you can’t avoid the simple fact that masks are still the best tool because person to person spread by droplets IN THE AIR are the MAIN way fly is spread.
There are other ways, but droplets from person to person IN THE AIR is the MAIN way flu is spread.
My whole point was that wearing masks probably decreased the amount of flu transmission, and studies back that up.
Cleaning and disinfecting and staying home probably ALSO helped, but wearing masks was the MAIN FACTOR.
Why in the hell do you have a problem digesting that?
