Ebola is a severe, often fatal disease that can occur in humans and some animals. It is caused by an infection with a virus.
Ebola is spread through direct contact with the blood or body fluids of an infected, symptomatic person. It is also spread through exposure to objects (such as needles) that have been contaminated with infected secretions. Ebola is not transmitted through the air, food or water. It can also spread when people have direct contact with dead bodies of people who died from Ebola or with infected bats, rodents, or primates.
