The rate of transmission at which the Ebola virus spreads is not dependant on any specific physical condition but a result of direct contact with the virus, according to the CDC. Ebola spreads only by direct contact with blood or body fluids, contaminated needles and objects, and infected animals.
The Ebola virus spreads more rapidly when medical staff do not practice sanitary procedures or use proper protective equipment, according to the CDC. It is thought that the Ebola virus may also be spread by the handling of bushmeat from infected animals, such as the monkey, bat or ape. The Ebola virus is believed to be spread through sexual contact even after a person recovers from infection. As of 2015, Ebola survivors must not have intercourse for a period of three months until more is understood concerning how or if Ebola is spread through intercourse.
The Ebola virus spreads through mucous membranes located in the mouth, eyes and nose, according to the CDC. It may also gain entry to the body through a small cut in the skin. Health care workers are at the highest risk for infection. Ebola can spread from patients to medical staff through common objects, such as bedding.
