This idea is further corroborated by Marburg virus outbreaks that have been associated with caves or mines heavily infested with bats. Some observations have shown the decrease in case fatality ratio after several generations of patient-to-patient passage. Originating in 1976 in equatorial Africa, past outbreaks with a few hundred cases had been contained within rural, forested areas in Uganda and Congo (Piot, 2012). You can read their DAILY Situation Summary. This vaccine is recommended as a pre-exposure vaccine for certain adults who are at risk of being exposed to Ebola virus (for example, outbreak responders, laboratorians or other staff at certain laboratories who handle specimens that might contain Ebola virus, and healthcare personnel working at state or federally designated special pathogens treatment centers). 2 0 obj Smither, Sophie J.

Ebola virus disease (EVD) in West Africa was first reported during early March 2014 in Guinea's 3 southeastern prefectures (Gueckedou, Macenta, and Kissidougou), which border Liberia and Sierra Leone; however, retrospective investigations indicate Ebola virus (EBOV) transmission might have occurred in Guinea since December 2013 (1-4).On March 27, 2014, EVD was reported in Conakry .
