More than 78 people in the African nation of Guinea are suspected to have died since January from one of the world's most lethal infectious diseases: Ebola.
According to the international aid organization Doctors Without Borders (MSF), the Ebola outbreak's scale is unprecedented. "We are facing an epidemic of a magnitude never before seen in terms of the distribution of cases in the country," Mariano Lugli, coordinator of MSF's project in Conakry, told Reuters.
The first new cases of the killer disease appeared more than six weeks ago in southern Guinea's, but it took authorities until last week to identify the killer as Ebola, which allowed the infection to spread. The World Health Organization announced Monday there had been two confirmed cases already in Liberia.
In its acute phase, Ebola causes vomiting, diarrhea and external bleeding. The disease was first recorded in 1979 in the Democratic Republic of Congo and has killed more than 1,500 people since.
