Ebola Timeline

October 14, 2014

The Ebola outbreak in West Africa is the largest Ebola outbreak in history. It can be traced back to a boy who died of Ebola in December; he lived in Guéckédou in southeastern Guinea, which is surrounded by Sierra Leone and Liberia. Easy movements in and out of these countries, combined with poor facilities and delayed identification, have contributed to Ebola’s rapid spread, creating a public health disaster. As of this writing approximately 3,000 people have died from Ebola since December and over 6,000 people have been infected. This particular strain of Ebola (i.e., the Zaire strain) was discovered in Zaire (now the Democratic Republic of Congo) in 1976, and is thought to be spread through animals, perhaps by bats. Prior Ebola outbreaks were easily contained because they occurred in sparsely populated regions.

On bioethics.com, we document disasters through the lens of news headlines and journal articles. The timeline of news events since March when the outbreak made international news highlights the outbreak’s rapid progression as well as bioethics questions that are specific to epidemics: the slow response of international aid groups, the use of Ebola drugs that were untested on humans, hastening clinical trials of Ebola remedies and vaccines, medical workers being flown back to their home country while infected West African medical workers must stay, appropriate allocation of resources from foreign countries, and containment practices that may violate human dignity.

Given that surveillance and response measures have held this terrifying disease in check for the past decade, why has the situation gotten so far out of hand this time?” (news.nationalgeographic.com/news/2014/07/140702-ebola-epidemic-fever-world-health-guinea-sierra-leone-liberia/)
