Ebola virus disease (EVD), or simply Ebola, is a highly infectious and often deadly disease caused by the Ebola virus. The virus was first identified in 1976 in a village near the Ebola River in the Democratic Republic of the Congo. Ebola is transmitted through direct contact with the bodily fluids of an infected person or animal, such as blood, saliva, urine, and feces. Symptoms of Ebola typically include fever, severe headache, muscle pain, weakness, fatigue, diarrhea, vomiting, abdominal pain, and unexplained bleeding or bruising. Research on Ebola has focused on developing vaccines, treatments, and prevention strategies to combat the spread of the virus. Current areas of research include vaccine development, studying the genetic diversity of the virus, understanding how the virus causes severe illness, and improving outbreak response and control measures. Overall, research on Ebola is critical in helping to prevent future outbreaks and improve the treatment of individuals affected by the disease.
