Endline prevalence survey

MALARIA, MALARIA
An endline cross-sectional survey took place in November 2018, 18 months after the installation of SET. In contrast to the baseline survey where households were the sampling unit, compounds (ranging from 1 to 5 households) were randomly selected from census lists of each cluster, and individuals were tested until approximately 70 people per cluster had been sampled. Anyone over the age of 6 months was invited to be part of the study. Participants were tested using RDT (SD Bioline Malaria Ag P.f/Pan; Standard Diagnostics; Seoul, South Korea) and had a blood smear taken for microscopy analysis, regardless of symptoms of malaria. A short questionnaire was also administered to collect information on house structure, household assets, intervention use, and potential malaria symptoms.The prevalence survey had 80% power to detect a 40% reduction in prevalence between the control arm and the SET arm, assuming a 40% prevalence in the control arm and a coefficient of variation between clusters of 0.5.
