Aren’t they checked before they get on the plane?
Screening is sort of a waste of time..in Israel, last Sunday a man flew in from Italy, he was screened, no fever, seemed fine, went home..went to four different locations in Israel, on Thursday he developed a high fever, he has coronavirus..the best thing to do is ban flights from countries who have over 100 cases of this, and only allow American citizens to come home and have them be quarantined til the correct amount of time has passed
