Since the origin of the pathogens was outside the US, I'd call that "imported".
YMMV.
No, Ebola was not imported, except to research laboratories over the decades, some Americans came home for medical treatment of the disease.
One traveler who was infected came into the U.S.
Still trying to make a mountain out something that never came to be a mountain?
The screaming crazies and the hysterics were wrong, and they were sure nasty at everyone who has proven to have been right.
Did we even lose any Americans to Ebola, I don remember, but I can show you the estimates on the threads here of tens of millions, of half of our population, and even up to 75% of the entire human race.
