CDC Offers Update on Cluster of Ebola Cases in Democratic Republic of the Congo

Published on: 

On May 11, 2017, the Ministry of Public Health of the Democratic Republic of the Congo notified international public health agencies of a cluster of suspected cases of Ebola Virus Disease (EVD) in the Likati health zone of the province of Bas Uélé. The report mentions nine cases, including two deaths, with a third death reported on May 12. Testing of samples was conducted by the Institut National de Recherche Biomedicale (INRB) in Kinshasa, with two samples testing positive for Ebola Zaire by RT-PCR. Teams from international agencies, including CDC, World Health Organization (WHO), MSF (Doctors without Borders), and others, are supporting the Ministry of Public Health’s epidemiologic, diagnostic, clinical, and communications efforts to respond to the outbreak. The response faces challenging logistical obstacles, including the remoteness of the area and limited services. Mobile diagnostic laboratories have been deployed to the affected areas.
