Over at Wired, this article does an excellent job summarizing why you should be concerned with Ebola in Africa, and maybe not worry about it as much in the US.
Especially worth reading this quote here:
“Ebola isn’t anywhere near as contagious as the flu, for example. Or measles, which is much more of a threat in the United States now that people are no longer routinely vaccinating their children. Scientists estimate that one person infected with measles can transmit the disease to as many as 18 others; for Ebola, that number is around two.”
It also does an excellent job of highlighting the concerns with the virus, and why you should and shouldn’t be worried.
