What is Ebola?
Ebola disease is a rare but serious viral hemorrhagic fever caused by infection with one of four orthoebolaviruses known to infect humans: Ebola virus, Sudan virus, Bundibugyo virus, and Taï Forest virus. Ebola can cause severe illness and death if not recognized and treated promptly. The virus spreads through direct contact with the blood or other body fluids of a person who is sick with Ebola or has died from the disease and does not spread through the air like influenza or COVID-19.
