About Ebola

What Is Ebola?

Ebola virus disease (EVD) is a severe, often fatal illness caused by the Ebola virus, a member of the Filoviridae family. It was first identified in 1976 in simultaneous outbreaks in Sudan and the Democratic Republic of Congo. The average CFR is around 50%, ranging from 25% to 90% depending on outbreak and response.

Transmission

Ebola spreads through direct contact with blood, body fluids, or tissues of infected humans or animals. It can also spread through contact with contaminated surfaces or materials. Burial practices that involve direct contact with the deceased are a major transmission route during outbreaks.

Symptoms

Symptoms begin 2–21 days after exposure with sudden fever, fatigue, muscle pain, headache, and sore throat. This progresses to vomiting, diarrhea, rash, impaired kidney and liver function, and in severe cases, internal and external bleeding.

Geographic Distribution

Ebola outbreaks primarily occur in Central and West Africa. Major outbreaks include the 2014–2016 West Africa epidemic (28,000+ cases) and ongoing outbreaks in DRC, Uganda, and Guinea. The virus persists in animal reservoirs (fruit bats) across sub-Saharan Africa.
