Following the outbreak of yellow fever in Angola in December 2015 and the subsequent confirmation of dozens of cases in the DRC, MSF teams were deployed in both countries to help contain the spread of the disease. In Matadi, the capital of Kongo Central, MSF teams has launched on 26 May a 10 days vaccination campaign. In total 370.000 people have been vaccinated.
MSF has also launched vector control measures in Kinshasa and Kongo Central. These activities are intended to combat the Aedes aegypti mosquito, the carriers of yellow fever. Homes are being sprayed or fumigated to kill adult mosquitoes and destroy breeding sites such as refuse or items containing stagnant water, where the mosquito lays its eggs. These activities are being carried out in locations where cases have been confirmed and in vulnerable locations such as hospitals, schools and markets.

Medecins Sans Frontieres (MSF) is conducting activities in the south-west of the Democratic Republic of Congo to stop the spread of Yellow Fever. The outbreak of the disease in DRC is linked to the epidemic that hit neighbouring Angola in December.
