The burden of and risk factors for trachoma in selected districts of Zimbabwe: results of 16 population-based prevalence surveys


The purpose of this study undertaken in 2014 and 2015 was to determine the prevalence of trachoma in 16 districts in Zimbabwe. A population-based prevalence survey was conducted in each district according to the methodology of the Global Trachoma Mapping Project.

The study concluded that the prevalence of active trachoma (TF) was above the WHO threshold for elimination as a public health problem in 11 districts – therein calling for the mass distribution of azithromycin, together with facial cleanliness and environmental improvement. The prevalence of trichiasis was above the WHO elimination threshold of 0.2% in 10 districts. A multifactorial risk factor analysis found that TF was less likely to be found at higher altitudes and increasing annual maximum temperatures.
