Cutting off all flights from Ebola infested African countries will help prevent the spread of Ebola by preventing the infected from entering our country.
Today, September 30th the CDC confirmed the first case of Ebola in the U.S. The infected came from Liberia during his incubation period. The incubation period of Ebola can last anywhere from 3-21 days. This period being so long it makes it next to impossible to detect the infected during this time frame.
Cutting off all flights coming out of the infected countries will help reduce the risk of this epidemic spreading more than it already has.
