Overview

Since March 2014, West Africa has experienced the largest outbreak of Ebola in history, with multiple countries affected.

In response to the outbreak, CDC activated its Emergency Operations Center to coordinate technical assistance and control activities with other U.S. government agencies, the World Health Organization, and other domestic and international partners. CDC also deployed teams of public health experts to West Africa. Widespread transmission of Ebola in West Africa has been controlled, although additional cases may continue to occur sporadically. However, because of ongoing surveillance and strengthened response capacities, the affected countries now have the experience and tools to rapidly identify any additional cases and to limit transmission.
