Nothing personal but I think it's probably just as well your wife's retired if she doesn't realize that different viruses have different ways of spreading.
Aerosol vs. droplet, for example.
Please, doctor, explain the difference to this non-medical noob, between aerosol and droplet. My nurse wife rants over and over about how the covid virus travels in droplets, which—allegedly—won’t pass through the holes in an N95 mask. My non-medical mind just can’t grasp how the virus knows to stay in the mask fibers once the droplet has dried. All the early “science” said the virus could live for days on inorganic surfaces, so what’s to prevent that 90nm virus from dropping like a pinball through the mask fibers once the droplet dried?
