The purpose of this study is to assess health activities to prevent measles in the province of Lomami in the Democratic Republic of Congo. In reality, despite the existence of vaccination against this disease, the incidence of morbidity remains high. Epidemiological surveillance of this disease still needs to be improved. Vaccine storage methods need to be analysed, and living conditions, especially housing, need to be improved. The involvement of community leaders in raising awareness of the fight against this disease is vital if this scourge is to be overcome.
