Another thread asks "is all this handwashing necessary?"
Someone cited an article in a popular magazine where the author champions the opinion of one scientist who got his "comment" published in a sub-journal of The Lancet.
I argue that the situation below is exactly what we need to protect ourselves against, by wearing gloves - whenever we go to a store we have to touch the entry door, shopping carts, the keypad on the credit card machine. And the last person to touch them was MINUTES ago, not many hours.
"In my opinion, the chance of transmission through inanimate surfaces is very small, and only in instances where an infected person coughs or sneezes on the surface, and someone else touches that surface soon after the cough or sneeze (within 1–2 h)."
Its so simple to wear light cloth work gloves & spray them with 80% isopropyl alcohol !
I recently read an article via JAMA about a study where they exposed humans to different concentrations of various Influenza strains. One had a 50% infectivity rate from 4 particles. Others, up to billions. I have not come across any estimates for COVID-19.
