Latest West Africa Ebola Fact Sheet

Key Developments

During the 21-day period ending on December 18, health actors in Liberia reported that only 20 percent of the 133 new Ebola Virus Disease (EVD) cases were among already identified contacts. These figures indicate that, despite an overall downward trend in case transmission, the vast majority of emerging cases were not being monitored by contact tracers. As such, Liberia continues to host numerous unidentified chains of transmission, and persistent surveillance efforts are vital to preventing another spike in the countrywide caseload.

The Government of Liberia (GoL) is no longer reporting active clusters of cases in Bomi County; however, Nimba County has recently reported cases, including an infected person originating from neighboring Guinea. Currently, seven counties are reporting cases, with Grand Bassa, Grand Cape Mount, and Montserrado counties accounting for the majority.

On December 15, the GoL reported no new laboratory-confirmed cases throughout the country, marking it the first day without a new confirmed case in the current outbreak. In the days thereafter, the GoL continued to report confirmed cases, indicating ongoing transmission of EVD.


In the wake of accelerated EVD transmission countrywide, Liberian President Ellen Johnson Sirleaf declared a state of emergency on August 6, enabling the GoL to deploy troops and police to impose quarantines, when necessary, to combat the spread of EVD.

On August 4, U.S. Ambassador Deborah R. Malac declared a disaster due to the effects of the EVD outbreak in Liberia. In response, USAID’s Office of U.S. Foreign Disaster Assistance (USAID/OFDA) and the U.S. Centers for Disease Control and Prevention (CDC) activated a U.S. Government (USG) Disaster Assistance Response Team (DART) to help coordinate and augment EVD outbreak response efforts throughout Liberia. As of late December, the USG had provided a total of nearly $815 million to support the humanitarian response in EVD-affected countries of West Africa.
