Ok, I didn't take time to read all the articles listed above... but because I work in a hospital, we have been given updates from time to time about outbreaks. One thing that has been stressed over and over is that ebola will be very limited in the US simply because of our level of hygiene. Yes, I know there are sections in this country where cleanliness is not practiced. The keys we were told were to keep clean. Especially washing our hands and a day doesn't go by where I haven't washed, alcohol'd my hands at least a dozen times. I noticed today at some eating establishments that they are requiring employees to not only wash their hands regularly, but are utilizing rubber gloves. As for how it spreads, I am not sure. Of course body fluid exposure is tops on the list. So, just keep up with the news (not mainstream of course) and make sure to have good, adequate cleaning supplies handy.
