Overview of Ebola virus disease in 2014

In late December 2013, a deadly infectious epidemic, Ebola virus disease (EVD), emerged from West Africa and resulted in a formidable outbreak in areas including Guinea, Liberia, Sierra Leone and Nigeria. EVD is a zoonotic disease with a high mortality rate. Person-to-person transmission occurs through blood or body fluid exposure, which can jeopardize first-line healthcare workers if there is a lack of stringent infection control or no proper personal protective equipment available. Currently, there is no standard treatment for EVD. To promptly identify patients and prevent further spreading, physicians should be aware of travel or contact history for patients with constitutional symptoms.
