Ebola is a highly infectious disease caused by the Ebola virus. It was first identified in 1976 in Sudan and the Democratic Republic of Congo. Ebola is transmitted through direct contact with the blood, body fluids, or organs of infected animals or people. The virus can cause severe symptoms, including fever, headache, muscle pain, weakness, diarrhea, vomiting, abdominal pain, and bleeding. In some cases, it can lead to organ failure and death. There is no specific treatment or vaccine for Ebola, but supportive care and early medical intervention can improve the chances of survival.
