Lack of household clustering of malaria in a complex humanitarian emergency: implications for active case detection.

Background: Malaria contributes to elevated morbidity and mortality in populations displaced by conflict in tropical zones. In an attempt to reduce malaria transmission in an internally displaced persons (IDP) camp in eastern Democratic Republic of Congo (DRC), we tested a strategy of active case detection of household contacts of malaria cases.

Methods: Prospective community-based survey.
