October 2021 Democratic Republic of the Congo, North Kivu Province


On October 8, 2021 the Ministry of Health (MOH) in the Democratic Republic of the Congo (DRC) announced an outbreak of Ebola virus disease (EVD) in Beni Health Zone, North Kivu Province. Subsequent cases have been confirmed in the same health zone. Beni, one of the epicenters of the 2018-2020 EVD outbreak in DRC, is not far from Butembo City, the site of two recent EVD outbreaks, one in 2018 and  another earlier in 2021.

Sequencing data from the first confirmed case in this outbreak shows a link to the 2018-2020 outbreak in the same region. This suggests that the new outbreak was likely caused by a persistent infection in an EVD survivor that led to either a relapse or sexual transmission of the virus.

CDC is working with the MOH and the World Health Organization (WHO) to implement response activities. An EVD surveillance system is in place, and contact tracing and vaccination activities are being carried out. The WHO Strategic Advisory Group of Experts on Immunization (SAGE) recommendsexternal icon that during an Ebola outbreak, all contacts and contacts of contacts should receive rVSVΔG-ZEBOV-GP unless they were vaccinated within the preceding six months.
