Ebola Disease

Ebola disease is caused by an infection with one of a group of viruses, known as ebolaviruses, that are found primarily in sub-Saharan Africa. Although Ebola disease is rare, people can get the disease through contact with an infected animal (bat or nonhuman primate) or a sick or dead person infected with an ebolavirus.

The U.S. Food and Drug Administration (FDA) has approved the Ebola vaccine, ERVEBO®, for the prevention of Ebola disease. ERVEBO vaccine has been found to be safe and protective against only the Zaire ebolavirus species of ebolavirus.

This mobile app estimates when a person with Ebola was exposed to the virus. Knowing when someone was exposed to Ebola is essential to establish chains of transmission. CDC in collaboration with the Johns Hopkins Applied Physics Laboratory designed the app for field staff with variable levels of education and knowledge of the natural disease progression of Ebola.
