How is Ebola spread?
The virus is spread through direct contact (through broken skin or mucous membranes) with blood and body fluids (urine, feces, saliva, vomit, and semen) of a person who is sick with Ebola, or with objects (like needles) that have been contaminated with the virus. Ebola is not spread through the air or by water or, in general, by food; however, in Africa, Ebola may be spread as a result of handling bushmeat (wild animals hunted for food) and contact with infected bats.
Can I get Ebola from a person who is infected but doesn’t have fever or any symptoms?
No. A person infected with Ebola is not contagious until symptoms appear.
