Didn't take long for someone to say that.
But this is a real phenomenon. People from third world areas have diseases we don't.
My brother in law used to be a health inspector in NY city. He would never eat at any restaurant there, and one of the reasons he gave was you just couldn't be sure that a worker wasn't carrying an exotic disease.
He will not eat at any buffet to this day. Come to think of it, we can barely find anyplace he'll eat.
