Ebola Virus Disease

West Africa has been experiencing a large outbreak of Ebola Virus Disease (EVD) since December of 2013. The nations of Guinea, Sierra Leone, Liberia and most recently Nigeria remain the primary areas affected. The number of cases continues to increase, and as of August 15, 2014, there were 2127 confirmed or suspect cases including 1145 suspected case deaths reported in the four affected West African nations.

There are no suspect or confirmed cases of Ebola in the United States, aside from two United States citizens who were transported to Emory University for further care after contracting the disease while caring for patients with EVD in Liberia. Though the risk of Ebola to the United States or Orange County is small, the potential exists for imported disease in persons traveling from countries where EVD is active. CDC has advised travelers to avoid all non-essential travel to Guinea, Sierra Leone, and Liberia, and has issued a lower level alert for Nigeria.

The California Department of Public Health (CDPH) continues to work with the health care community and local health jurisdictions to prepare for the event that a returning traveler from these countries develops illness that may be concerning for EVD. Early identification of such cases and prompt infection control implementation will be key components in prevention of Ebola transmission.
