This article is about a biological genus. For the specific virus signs and symptoms of ebola pdf for the majority of human infections, see Ebola virus. Phylogenetic tree comparing ebolaviruses and marburgviruses. Numbers indicate percent confidence of branches.

The genus Ebolavirus is a virological taxon included in the family Filoviridae, order Mononegavirales. Reston virus, has caused EVD in other primates. Ebolaviruses were first described after outbreaks of EVD in southern Sudan in June 1976 and in Zaire in August 1976. Researchers have now found evidence of Ebola infection in three species of fruit bat. The bats show no symptoms of the disease, indicating that they may be the main natural reservoirs of the Ebolavirus. It is possible that there are other reservoirs and vectors. Understanding where the virus incubates between outbreaks and how it is transmitted between species will help protect humans and other primates from the virus.

Ebolavirus is always to be capitalized, italicized, never abbreviated, and to be preceded by the word “genus”. The genera Ebolavirus and Marburgvirus were originally classified as the species of the now-obsolete Filovirus genus. There have been more outbreaks of Zaire ebolavirus than of any other species. The first outbreak took place on 26 August 1976 in Yambuku. 4 per site per year and are thus one fourth as fast as influenza A in humans. Extrapolating backwards, Ebolavirus and Marburgvirus probably diverged several thousand years ago.

In particular, the generic term “Ebola virus” is widely used to refer specifically to members of the species Zaire ebolavirus. A 2013 study isolated antibodies from fruit bats in Bangladesh, against Ebola Zaire and Reston viruses, thus identifying potential virus hosts and signs of the filoviruses in Asia. A recent alignment-free analysis of Ebola virus genomes from the current outbreak reveals the presence of three short DNA sequences that appear nowhere in the human genome, suggesting that the identification of specific species sequences may prove to be useful for the development of both diagnosis and therapeutics. 2010 proposal specifically suggested that “Ebola virus” be given a taxonomic rank of “Virus” within the species Zaire ebolavirus.
