Germs, viruses and fuel pump handles and doors

I wonder if there’s any way to know if the rapid spread of Covid19 in Italy had anything to do with cultural habits like bringing your own grocery bags to the store? ;)

I have no control over where everyone else’s bags have been before being placed in the common area where mine will be.

Oregon outlawed “single use” plastic bags. The thing is every one we’ve ever brought home was used again and more. Now we have to buy more garbage bags.
