Description
Summary:Summary Objectives  To investigate the relationship between distance to water source, altitude and active trachoma in children in Rombo district, Tanzania. Methods  In each of Rombo's 64 villages, 10 balozis (groups of 8–40 households) were selected at random and all resident children aged 1–9 years were examined for clinical signs of active trachoma. The households of these children and village water sources were mapped using differentially corrected global positioning system data to determine each household's altitude and distance to the nearest water supply. Results  We examined 12 415 children and diagnosed 1171 cases of active trachoma (weighted prevalence = 9.1%, 95% CI: 8.0, 10.2%). Active trachoma prevalence ranged from 0% to 33.7% across villages. Increasing distance to the nearest water source was significantly associated with rising trachoma prevalence (age‐adjusted odds ratio for infection (OR) for highest quartile compared to lowest = 3.56, 95% CI 2.47, 5.14, P for trend
