Ebola virus disease (EVD), one of the deadliest viral diseases, was discovered in 1976 when two consecutive outbreaks of fatal hemorrhagic fever occurred in different parts of Central Africa. The first outbreak occurred in the Democratic Republic of Congo (formerly Zaire) in a village near the Ebola River, which gave the virus its name. The second outbreak occurred in what is now South Sudan, approximately 500 miles (850 km) away.

Ebola virus disease (EVD) is a deadly disease with occasional outbreaks that occur primarily on the African continent. EVD most commonly affects people and nonhuman primates (such as monkeys, gorillas, and chimpanzees). It is caused by an infection with a group of viruses within the genus Ebolavirus.

The largest outbreak to date took place in West Africa between March 2014 and June 2016, affecting primarily Guinea, Liberia and Sierra Leone. Over 28,000 cases were recorded.

The most recent EVD outbreak has been ongoing in the Democratic Republic of Congo (Equateur Province) since June 2020. As of 9 August 2020, there

About 1500 species of infectious organisms are known to be pathogenic to humans, including 217 viruses and prions. Unpredictable hemorrhagic fever disease outbreaks are caused by different species of Ebola viruses, as well as Marburg virus associated with 90% fatality rates. The ongoing multinational Ebola outbreak posed a serious threat to the countries of West Africa and beyond due to its unprecedented magnitude.

An Ebola vaccine, rVSV-ZEBOV, was approved in the United States in December 2019. It appears to be fully effective ten days after being given. It was studied in Guinea between 2014, and 2016. More than 100,000 people have been vaccinated against Ebola as of 2019.
