ebola epidemiological triangle
[24]Report of an International Commission. The first cases of Ebola virus infection were reported in Zaire (now known as the Democratic Republic of the Congo [DRC]) in 1976. It is important to note that the airborne transmission of Ebola has not been documented, which is comparable to how other respiratory viruses such as the severe acute respiratory coronavirus 2 (SARS-CoV-2) are spread. No additional confirmed or probable cases were identified, and the outbreak was declared over on September 27, 2022. The best way to understand the epidemiologic triangle is to see how epidemiologists use it to explain the spread of existing diseases.

Abstract Ebola virus disease (EVD) is one of the most virulent pathogens among viral hemorrhagic fevers affecting economically deprived countries of the world with reported case fatality rates of up to 90% due to multi-organ failure and severe bleeding complications. The virus enters the body through broken skin, through the eyes, nose or mouth, or through sexual contact. For graphs, geographical distribution and more details see the WEEKLY report (on Wednesdays).
