There is, but it's not the detailed screening we were talking about, where people arrive and they get fully checked out for things like hepatitis or HIV. You don't see that when you walk through an airport. The airport screening is more about somebody who has one or more of those 56 diseases that are reportable. They go past with a florid rash and a fever, and they look sick. The officials will be wondering whether that person has measles, or something like that.
