What is Ebola virus disease and its definition

What is Ebola virus disease?

Ebola disease is a hemorrhagic fever caused by a type of RNA virus. Ebola is highly contagious and often fatal. Ebola is transmitted through contact with the body fluids of an infected person. It was discovered in 1976 in Africa and is named after a river in the Democratic Republic of the Congo. There are four subtypes of this virus of which one type appears to affect only primates. The rest of three can infect and spread from human to human.

In an outbreak, the first infection is usually occurs from an affected animal to humans. The virus infection can spread through contaminated needles, body fluids, vomit, blood, faeces, urine and direct skin contact. The infection becomes highly contagious in its later stages. The incubation period spans between 2-21 days. There is high mortality rate among the infected. Even the dead body may remain contagious up to three days. Health care personnel attending EVD patients are required to wear protective equipment. There is no standard treatment for this disease.
