Three annual community-based cross-sectional surveys were conducted at baseline and following 12 and 24 months as part of a cluster-randomised, controlled trial - the TUMIKIA Trial - comparing annual or biannual community-wide treatment targeting all ages with annual school-based treatment targeting 2–14 year olds. Household demographics, socioeconomic status, and water and sanitation conditions were collected through structured questionnaires. Structured observations were made of household sanitation facilities. Individuals aged two years and above were randomly selected during households surveys and requested to provide stool samples, which were assessed for presence and intensity of STH infection using the Kato-Katz thick smear method. Information on recent deworming, sanitation and hygiene behaviours, and shoe-wearing was also collected from individuals who provided stool samples. Data are provided as a comma separated value file with accompanying data dictionary.
