Ebola

Ebola is a rare but severe and often fatal illness caused by infection with one of the Ebola virus strains, which spreads through direct contact with blood or body fluids of infected people or animals. The virus triggers a rapid and overwhelming immune response that can cause internal and external bleeding, organ failure, and shock, with death rates ranging from 25 to 90 percent depending on the virus strain and quality of medical care. Scientists believe the virus naturally lives in fruit bats and occasionally spills over into human populations through contact with infected wildlife, making it a zoonotic disease that requires careful monitoring and swift public health response.
