Prevalence of trachoma in the Republic of Chad: results of 41 population-based surveys


The purpose of this study undertaken in 2014-2015 was to estimate the prevalence of trachoma in suspected-endemic areas of Chad, and thereby determine whether trachoma is a public health problem requiring intervention. The study divided the suspected-endemic population living in secure districts (40) into 46 evaluation units (EUs), and used the standardised methodologies of the Global Trachoma Mapping Project.

The results demonstrated that trachoma is a public health problem in Chad, and implementation of the SAFE strategy is required. Specifically: the management of trichiasis (S) is needed in 29 EUs; the mass distribution of antibiotics (A) and interventions for facial cleanliness (F) and environmental improvement (E) are required in 16 EUs.
