As NPR reports, it’s pretty simple. While Ebola has a high mortality rate in Africa (about 70 percent), there are two factors that limit its spread:
1. Ebola doesn’t spread through the air. To contact the disease, you have to be in close contact with bodily fluid such as blood or vomit containing the virus.
2. And then there’s this:
people with Ebola aren’t contagious until they show symptoms. So to stop the chain of transmission, all health workers in Texas have to do is get the people possibly infected by the sick man into isolation before these people show signs of Ebola.
So there’s no reason to freak out about the disease.
