Household and Parasitology Survey, Kwale County, Kenya, 2015

A community-based cross-sectional survey was conducted as the baseline for 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 a structured questionnaire. 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.

本研究作为整群随机对照试验（cluster-randomised controlled trial）——TUMIKIA试验——的基线调查，采用社区为基础的横断面研究设计，对比两种驱虫干预方案：其一为针对全年龄段的每年或每两年一次的社区全员治疗，其二为针对2-14岁人群的每年一次的校内治疗。研究通过结构化问卷收集家庭人口统计学特征、社会经济状况以及饮水与卫生设施条件相关数据，并针对家庭卫生设施开展标准化观察记录。在家庭调查中随机选取2岁及以上的受试者，邀请其提供粪便样本；随后采用Kato-Katz厚涂片法（Kato-Katz thick smear method）检测样本中土壤传播蠕虫（Soil-transmitted helminths, STH）的感染情况与感染强度。同时向提供粪便样本的受试者收集近期驱虫治疗、卫生设施使用与个人卫生行为以及穿鞋行为相关信息。本数据集以逗号分隔值（Comma Separated Values, CSV）文件格式提供，并附带配套的数据字典。
