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 ...
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 ]
Transmission of the ebolaviruses between natural reservoirs and humans is rare, and outbreaks of Ebola virus disease are often traceable to a single case where an individual has handled the carcass of a gorilla, chimpanzee, bats, [9] or duiker. [10]
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
The lack of written records in many places and the destruction of many native societies by disease, war, and colonization make estimates uncertain. Deaths probably numbered in the tens or perhaps over a hundred million, with perhaps 90% of the population dead in the worst-hit areas.
If a person infected with the Ebola virus rides the subway and has a body fluid (such as mucus from sneezing) on his or her hand, and then touches the railing on a subway, the virus can live up to ...
Of the four disease-causing viruses in the genus Ebolavirus, Ebola virus (or the Zaire Ebola virus) is dangerous and is the virus responsible for the epidemic in Western Africa. [ 236 ] [ 237 ] Since the discovery of the viruses in 1976, Ebola virus disease has been confined to areas in Middle Africa, where it is native.
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.
