>> the prudence of bringing a contagious untreatable disease here <<
Myabe it’s a bit late to be concerned, because the fatal version of the virus was brought to the USA some time ago (in “test tubes” to be sure) for research purposes.
The fact that Ebola has been here so long with no fatal consequences shows that proper handling in secure facilities (something lacking in West Africa!) can eliminate major dangers.
Also, a very weak version of the virus, “Reston Ebola,” was brought into the USA via research monkeys from the Philippines, and at least four humans in Virginia and Texas developed antibodies to this form of the disease. But none of these four people actually got sick.
So we have been lucky so far. Just like with the smallpox fond in the back if a closet. So much for our sophisticated specimen handling
