Methods: A confirmed case was defined as a person with or without clinical symptoms, in whom malaria parasites including gametocytes were detected using rapid diagnostic tests (RDT) or microscopy. A passively detected case triggered an investigation that targeted the index case household and households in a 500m radius. All consenting community members received an RDT. Demographic, clinical, and risk factor data was obtained from cases. We described the cases using frequencies, proportion, and summary statistics.
