Description
Summary:On Apr 23, 2016, the Democratic Republic of the Congo (DRC) Ministry of Health reported an outbreak of yellow fever. As of May 24, 2016, among 41 confirmed yellow fever cases, 31 had occurred in Kongo Central Province, in the western part of the country bordering Angola, where a large yellow outbreak had begun in December 2015. In response, during May 25-Jun 7, 2016, the DRC Ministry of Health administered approximately 240,000 doses of yellow fever vaccine to all persons aged ≥9 months during a mass vaccination campaign in Matadi, one of 31 health zones in the Kongo Central Province. The administrative vaccination coverage, was estimated to have reached >99%. This enhanced surveillance program found that the passive yellow fever adverse events following immunization (AEFI) AEFI system failed to identify half of all AEFIs that were identified through active surveillance, including all of the serious AEFIs.
