Here are two good things about the Ebola virus. It is unlikely to mutate into a version that can spread through the air, as some other viruses have done. And people who have been infected by Ebola cannot pass it on to others during the incubation period (between two and 21 days). Only when they develop detectable symptoms, notably fever, do they become infectious to others, and only by the transfer of bodily fluids.
Here are three bad things about Ebola. The "bodily fluids" that can transmit it include even the tiniest droplet of sweat: Just the slightest touch can pass the virus on.
The death rate for those who become infected is 70 percent. And the U.S. government's Centers for Disease Control warned recently that we could have 1.4 million cases of Ebola by January.
