Ebola Virus Disease Nancy A. Faria Quinebaug Valley Community College Ebola is not alive because it is a virus. The definition of a living organism is something that is capable of metabolism, growth, reaction to stimuli and reproduction. Ebola needs host cells, as in humans and animals, to replicate this very deadly virus. The Ebola virus disease (EVD), formerly known as Ebola hemorrhagic fever, contains five distinct species in the Genus Ebolavirus. 1. Zaire ebolavirus (EBOV) 2. Sudan ebolavirus (SUDV) 3.

EVD initially appeared in 1972, location unknown, when three physicians did an autopsy on a patient thought to have died from yellow fever. Two out of the three physicians died of EBOV, exhibiting a 67 percent mortality rate. The first outbreak of EBOV occurred in 1976 in Yambuku, Zaire (now known as the Republic of Congo), Africa. 318 people were infected and of that 280 people died with a mortality rate of 88 percent.

The outbreak was among crab-eating macaques’ monkeys from the Philippines, where the virus has also infected pigs. (Harper, 2005).

Her symptoms were similar to dengue fever. She made a full
