Ebola virus disease (EVD), also known as Ebola hemorrhagic fever, is a severe and often fatal illness in humans and nonhuman primates such as monkeys, gorillas, and chimpanzees. The disease is caused by the Ebola virus, which was first identified in 1976 in two simultaneous outbreaks in Sudan and the Democratic Republic of Congo (then Zaire).
The virus is believed to be transmitted to humans from wild animals, such as fruit bats, through contact with their bodily fluids. Once the virus is introduced into the human population, it can spread through human-to-human transmission via direct contact with the blood, secretions, organs, or other bodily fluids of infected individuals.
Since its discovery, there have been multiple outbreaks of Ebola virus disease in Africa, with the most severe outbreak occurring in West Africa from 2014 to 2016. During this outbreak, more than 28,000 cases were reported, resulting in over 11,000 deaths. The outbreak highlighted the need for improved surveillance, preparedness, and response measures to prevent and control the spread of the virus.
In recent years, there have been sporadic outbreaks of Ebola in various African countries, with the most recent outbreak occurring in the Democratic Republic of Congo in 2021. Efforts to control the spread of the virus have included vaccination campaigns, improved infection control measures, and public health education.
Research into Ebola virus disease continues, with ongoing efforts to develop effective treatments and vaccines to prevent future outbreaks and reduce the impact of the disease on affected communities.
