Ebola hemorrhagic fever is a serious and often fatal disease that occurs in humans and primates. Ebola viruses are part of the filovirus family. The Ebola virus is the cause of infection of this disease. There are four subtypes of the Ebola virus that have appeared in humans: Ebola Sudan, Ebola Zaire, Ebola Côte d'Ivoire and Ebola Bundibogyo. There was also a case of Ebola occurring in a non-human in Reston, Virginia. The Zaire virus was the first Ebola virus discovered and is also considered the most deadly form of the virus. Since its discovery through 2014, there have been only 1,850 cases of the virus and only 1,200 people have died from it. The Ebola virus first appeared in 1976, in the African countries of Sudan and what is now known as the Democratic Republic of Congo, formerly Zaire. Ebola takes its name from a river valley in the Democratic Republic of Congo. The first recorded outbreak of this virus infected more than 284 people and killed approximately 53% of those infected. During the second Ebola outbreak, 318 people were infected, 88% of whom died from the virus. The Ebola case in Reston, Virginia, ultimately did not infect any humans. The current prevalence of Ebola hemorrhagic fever is relatively low. This usually only happens during sporadic outbreaks. The Ebola outbreak is most widespread in Africa, but there have been other cases in countries outside Africa. The only human outbreaks of the virus have occurred in Africa. It is also believed to occur in more isolated accounts that are not officially recognized. The origins of this disease are still unknown and scientists do not know the exact cause of how it begins to spread.
