Ebola, also known as Ebola virus disease (EVD) and Ebola hemorrhagic fever (EHF), is a viral hemorrhagic fever in humans and other primates, caused by ebolaviruses. [1] Symptoms typically start anywhere between two days and three weeks after infection. [ 3 ]
Epidemics of infectious disease are generally caused by several factors including a change in the ecology of the host population (e.g., increased stress or increase in the density of a vector species), a genetic change in the pathogen reservoir or the introduction of an emerging pathogen to a host population (by movement of pathogen or host).
The term emerging disease has been in use in scientific publications since the beginning of the 1960s at least [18] and is used in the modern sense by David Sencer in his 1971 article "Emerging Diseases of Man and Animals" [19] where in the first sentence of the introduction he implicitly defines emerging diseases as "infectious diseases of man ...
Ebola is a terrifying virus which, if left untreated, causes bleeding inside the body and through the eyes, nose, mouth and rectum. Case fatality rates have varied from 25% to 90% in past ...
The Calomys callosus field mouse is a natural carrier of the virus, the symptoms of which are Ebola-like and include bleeding, high fever, pain, and rapid death. Machupo kills between a quarter ...

An emergent virus (or emerging virus) is a virus that is either newly appeared, notably increasing in incidence/geographic range or has the potential to increase in the near future. [1] Emergent viruses are a leading cause of emerging infectious diseases and raise public health challenges globally, given their potential to cause outbreaks of ...
Ebola & Marburg virus diseases Viruses in this family cause hemorrhagic, or bloody, fevers, which are typically accompanied by bleeding from bodily orifices and/or internal organs.
