Ebola Virus Disease (EVD) is a severe and often fatal illness caused by the Ebola virus. It is transmitted to humans through contact with infected animals, such as bats or monkeys, and spreads between people through bodily fluids. Symptoms typically include fever, severe headache, muscle pain, and gastrointestinal issues, often leading to bleeding. The disease was first identified in 1976 near the Ebola River in the Democratic Republic of the Congo. Outbreaks have occurred primarily in Africa, with significant public health responses required to control its spread. Vaccines and treatments are being developed to help manage EVD outbreaks.
