The Catholics will be the first to go.
Have you ever been to a Sunday mass?
You can’t get out of there without shaking hands with a least a dozen different people.
And if you take the communion, the priest handles every piece of bread, and if you drink the wine it’s the same glass that a hundred of other people just used. Yes they wipe it down a bit but I doubt that helps much.
And on your way out of the church you shake hands with the priests that everyone else just shook hands with.
I can’t of a place where the virus won’t spread faster than a church...
