Summary The objective of this study was to use a modified Lot Quality Assurance Sampling methodology to classify communities according to prevalence of active trachoma and to estimate the prevalence of trachoma and trichiasis in Nioro department, Kaolack Region, Senegal. A survey was conducted using twostage cluster sampling to select 50 children aged 2β5 years in each of 33 clusters. In total 1648 children were examined for active trachoma. Information on trachoma risk factors was collected through interviews with the mother or the household head of the child. Adults (>40 years) with trichiasis were identified through case finding. Nineteen clusters had a low prevalence of active trachoma in children aged 2β5 years (<20%), 11 had medium prevalence (20β40%) and three had high prevalence (>40%). The prevalence of active trachoma in children aged 2β5 years was 17.4 % (95 % CI 12.9β21.8%). Multivariate-adjusted predictors of active trachoma were: age, facial cleanliness, hygiene practices and keeping cattle in the household. The prevalence of trichiasis in adults aged over 40 years was 1.77 % (95 % CI 1.24β2.51), equating to 985 adults (95 % CI 765β1250) with trichiasis in Nioro department. In conclusion, a survey using rapid methodology showed that trachoma is a problem of public significance in Nioro department
