What causes Ebola and Marburg virus infection?
Ebola and Marburg viruses usually infect animals living in Central and West Africa. But once they infect people, they can spread rapidly. People can get infected by:
Touching or eating infected animals
Touching infected people
Touching bodies of people who died from the infection
The virus is in almost all body fluids from infected people and animals. This includes blood, saliva, vomit, urine, stool, sweat, breast milk, and semen. You can also get the virus by touching things that have touched any of these fluids, like soiled clothing or bedding. That means you're at high risk if you are:
A health care worker
A family member of an infected person
Someone who touches dead bodies during funeral preparations or ceremonies

Bleeding under your skin (purple spots or patches), from your mouth or nose, or from organs inside your body
A rash on your chest and belly
Coma (when you're unconscious and can't be woken up)
