where did the ebola virus originated
By the time the Ebola virus epidemic in West Africa began in 2013, there were at least nine different candidate treatments. Several trials were conducted in late 2014 and early 2015, but some were abandoned due to lack of efficacy or lack of people to study.rom 1976 (when it was first identified) through 2013, the World Health Organization reported 1,716 confirmed cases. The largest outbreak to date is the ongoing 2014 West Africa Ebola virus outbreak, which has caused a large number of deaths in Guinea, Sierra Leone, and Liberia.
