Compassion for one person doesn't justify endangering the whole population. The doctor took a risk and lost . I respect his sacrifice but he should not have been brought back to the USA.
Ebola is not an airborne infection, nor would it likely have survived the fire that would occur after a plane crash.
It is spread by fluid contact. Ebola is not particularly contagious, it is simply very difficult to treat.
Four months in three countries that are pretty much the definition of backwards, it has spread to about 1000 people. These are people who eat monkeys they find dead on the ground (dead because they died of Ebola, for example). Their culture almost seems designed to help spread Ebola.
If we can’t handle a couple of cases of Ebola, we won’t survive a real outbreak of disease.
“I respect his sacrifice but he should not have been brought back to the USA.”
Even stupidity could see that. Bringing him back can only be motivated by Evil.
