Hand hygiene intervention to optimise helminth infection control: baseline data for Mikono Safi - A school-based cluster-randomised controlled trial in NW Tanzania
These data were collected during a cross-sectional survey conducted in primary schools in north western Tanzania at the beginning of a 12 month intervention period. The intervention was implemented using a cluster randomised trial design with schools as the units of randomisation. A random sample of children was selected in each participating class (class 1 to 6; approximately 35 children per class) in each school (n = 16 schools) to provide baseline data. The purpose of the trial was to examine whether whether a hand hygiene intervention implemented in schools could sustain the effects of deworming on the prevalence of soil transmitted worm infection (Ascaris lumbricoides and Trichuris trichiura) in school children. The survey data contained in these datasets were obtained after a deworming campaign conducted prior to intervention. The data contains information on the characteristics of children included in the baseline survey including: sociodemographic information; deworming history; handwashing behaviour; food handling at home and availability of latrine facilities at home; and personal risk factors associated with soil transmitted worm infection. The dataset also contains laboratory data from stool samples of egg counts for specific worm species and binary variables derived from the egg count variables to determine the prevalence of infection.
