The person that leaves Africa infected with Ebola will not infect anyone else before they die? Why the idea that one person has to bring Ebola from Africa all the way to the US? I was under the impression that Ebola spreads person to person. Ever watch a relay race?
They aren’t infectious until they are symptomatic, and the level of infectiousness increases as the disease progresses. Ebola, when it hits, hits hard, so the person would likely be abandoned pretty quickly. Assuming the worst-case scenario, that they would spread it to others in the group before they are abandoned—the most likely outcome would be that the whole group dies.
The incubation period is from 2-21 days, with the average around 8. With a 45 day journey to our border, someone with Ebola isn’t going to make it.
