AIDS, Legionairre's Disease, and Lyme Disease are three relatively recent situations the US medical system has absorbed. There must be a limit to how many it can absorb, especially with our expanded third world population and a larger percentage of the population economically challenged.
Well, when considering Ebola, I try to keep in mind that until this last multiple location outbreak in West Africa, the disease, as scary as it is, had killed less than 2000 people since 1976.
Based on the crowded conditions, If the virus was more mobile, the damages would have been many times greater, but the virus is not that mobile and is only transmitted in great numbers at the patients end stage of infection when they obviously can’t travel.
When you look at this and a number of other factors. I have to conclude that at this time, with this specific virus, It is unlikely to become a wide ranging issue, especially in the US. But I think that the EU is more likely to see it then we are because of their vast numbers of migrants from Africa.
All this taken into account, I don’t feel threatened by it..as a American. I would if I were in Africa, but based on what I am seeing, they are not nearly as concerned as we are. (or seem to be)
