The school needs confirmation from the CDC.
Screw that. The school is the one who will get sued if they don’t do anything.
Frankly, each school needs to ask, “Have you been in Western Africa the past 90 days?” If so go find a nice private school somewhere.
To this day I can’t give blood because of the Mad Cow scare back in the 90s. Close off the borders to West Africa travelers. They’ll get over it. Or die trying.
