Ebola Virus Disease (EVD) is a deadly disease. Ebola mostly affects people and non human primates. EVD was formerly known as Ebola hemorrhagic fever. Ebola virus disease was first appeared in 1976 involving 284 cases in which there were 151 deaths, centered in Sudan, and 318 cases with 280 deaths recorded in Democratic Republic of Congo near Ebola River.
The virus is transmitted to people from wild animals and spreads in the human population through human to human transmission. Ebola virus is transmitted through contact with blood or body fluids of a person who contracted or died from EVD, contaminated objectives like needles, clothings and infected animals or bush meat. EVD has an incubation period of 2-21 days, and the infection has an acute onset without any carrier status.
Symptoms and Signs
- Abrupt onset of fever, chills, malaise, anorexia, severe headache
- Some may develop a diffuse maculopapular rash by days 5-7 of illness, mainly on the trunk.

Practicing careful hygiene, avoid or handle carefully in funeral or burial rituals that require handling the body of some who has died from Ebola. Avoid from contact with infected fruits bats or monkeys and the consumption of their raw meat.
