The presence of the Zaire ebolavirus in naturally infected fruit bats was first documented when viral RNA and antibodies were detected in three different bat species of the Pteropodidae family: Hypsignathus monstrosus, Epomops franqueti, and Myonycteris torquata. As each country must strengthen its preparedness and response system to prevent eventual Ebola outbreaks in the future, adequate knowledge about the ecology and transmission of this disease is of the uttermost importance. On March 23, the WHOs Regional Office for Africa (AFRO) released the first Ebola report on the emergence of the disease in Guinea. (4) The disease was originated from and named after a river in the Democratic of Congo. The disease was then contained, however sporadic outbreaks of the Zaire and Sudan Ebola subtypes have risen in the Democratic Republic of the Congo, Gabon, Uganda, and Sudan; one of the latest outbreaks was in the Democratic Republic of the Congo in September of 2007.

Ebola virus can spread to people when they have contact with an infected animals blood, body fluids, or tissues. Characteristic burial ceremonies where mourners have direct contact with the body of the deceased can also represent an important path of transmission. Reporting time of the first cases of Ebola to WHO has been reduced (P = .017) and case fatality (P = .028) has gone from 88% to 62% in the period studied.

As a transmittable disease, progression of the virus had been thought to be linked to higher probabilities of transmission, and therefore safety of persons in contact with infected patients was in question (Yamin et al., 2015). FOIA People at higher risk of infection include healthcare workers, family members or others who have close contact with infected people or who have contact with their bodies during funerals or burying rituals. https://www.nejm.org/doi/full/10.1056/NEJMoa1411100#t=article Model-based evaluation of the impact of prophylactic vaccination applied to Ebola epidemics in Sierra Leone and Democratic Republic of Congo.
