West African countries and international health organizations adopted a fresh strategy on Thursday to fight the world's deadliest Ebola epidemic, which has killed hundreds of people in Guinea, Sier

THE United Nations reassured west Africa yesterday that the world’s deadliest-ever Ebola epidemic could be stopped in its tracks, telling the region’s health ministers: “We can handle this.”

This is a map by Centers for Disease Control and Prevention on Ebola Hemorrhagic Fever outbreaks by species and size in various countries across Africa, 1976-2014.

An outbreak of Ebola virus disease (EVD) in West Africa, with onset in early February 2014, is evolving in Guinea and Liberia. This is the first such outbreak in the area. The first cases were reported from the forested region of south-eastern Guinea.

Ebola viruses (EBOV) cause often fatal hemorrhagic fever in several species of simian primates including human. While fruit bats are considered natural reservoir, involvement of other species in EBOV transmission is unclear. In 2009, Reston-EBOV was the first EBOV detected in swine with indicated transmission to humans. In-contact transmission of Zaire-EBOV (ZEBOV) between pigs was demonstrated experimentally. Here we show ZEBOV transmission from pigs to cynomolgus macaques without direct contact.

Using S-I-R and S-E-I-R models, it was possible to simulate two Ebola outbreaks: the 1976 outbreak in Yambuku, Zaire and the 1995 outbreak in Kikwit, Zaire. The dynamics of these models are determined by the per-capita death rate of infected individuals and the per-capita effective contact rate of an individual contracting the disease.
