Presumably once the vomit dries the virus dies, but that could take days.

Especially in outdoor urban settings and mass transit during the winter months. That virus starts to be come very stable at <39 degrees fahrenheit. They keep telling us we are different than Africa. They don't know how right they are.

Imagine having infectious vomit on the sidewalk with snow.

I’ll resist the temptation to eat snow off the sidewalk. It is interesting that they can culture virus from frozen specimens (liquid nitrogen). So there’s really no limit to the amount of cold it can handle.
