Understanding Ebola Virus Disease
What is Ebola Virus Disease?
Ebola Virus Disease (EVD) is a severe and often fatal illness caused by the Ebola virus. It belongs to the family Filoviridae and is characterized by its high mortality rate, ranging from 25% to 90%. The virus primarily affects humans and nonhuman primates, such as monkeys and gorillas. EVD was first identified in 1976 during two simultaneous outbreaks in Sudan and the Democratic Republic of Congo (formerly Zaire). The disease is characterized by fever, fatigue, muscle pain, headache, and sore throat, followed by vomiting, diarrhea, rash, impaired kidney and liver function, and, in some cases, internal and external bleeding.
History of Ebola Virus Disease
The history of Ebola Virus Disease dates back to 1976 when the virus was first identified and named after the Ebola River in the Democratic Republic of Congo. Since then, multiple outbreaks have occurred primarily in Central and West African countries. The outbreaks have varied in scale and severity, with the largest outbreak occurring between 2014 and 2016 in West Africa, where over 28,000 cases were reported, and more than 11,000 lives were lost. This outbreak led to a global response and highlighted the need for better preparedness and response strategies.
Transmission of Ebola Virus Disease
Ebola Virus Disease is transmitted through direct contact with the blood, secretions, organs, or other bodily fluids of infected animals, including fruit bats, primates, and humans. Once a person is infected, the virus can be spread through direct contact with the blood or body fluids of an infected individual. This includes contact with contaminated needles, infected surfaces, or through close contact with a person who is sick with Ebola. It is important to note that Ebola is not an airborne virus and cannot be transmitted through casual contact or through the air.
