An overview of Ebola virus disease.

Abstract

Ebola virus disease (EVD), formerly known as Ebola hemorrhagic fever, is a severe, often fatal illness in humans. Ebola virus (EBOV) is transmitted through contact with blood or body fluids of a person who contracted or died from EVD, contaminated objects like needles and infected animals or bush meat. EVD has an incubation period of 2 to 21 days, and the infection has an acute onset without any carrier status. Currently, there is no standard treatment for EVD, so it is important to avoid infection or further spreading of the virus. Although historically the mortality of this infection exceeded 80%, modern medicine and public health measures have been able to lower this figure and reduce the impact of EBOV on individuals and communities. Its treatment involves early, aggressive supportive care with rehydration. Clinicians should consider the possibility of EVD in persons with travel or exposure history with the incubation period presenting constitutional symptoms in order to promptly identify diseased patients, and prevent further spreading of the disease.
