How doctors test for Ebola

Health officials are now monitoring 50 people in Texas for signs of Ebola via twice-daily temperature checks, and in recent days, there have been reports of people in other areas of the country — including Washington, D.C.— suspected of having the virus, although most have been ruled out. But why can't all these people just be tested for Ebola as soon as possible? Ebola is difficult to diagnose when a person is first infected because the early symptoms, such as fever, are also symptoms of other diseases, such as malaria and typhoid fever.
