Azithromycin Reduction to Reach Elimination of Trachoma (ARRET): study protocol for a cluster randomized trial of stopping mass azithromycin distribution for trachoma.
Summary
The investigators propose a randomized controlled trial of discontinuation versus continuation of annual mass azithromycin distribution in hypoendemic communities of Maradi, Niger. The investigators will randomize communities with up to 20% Trachomatous Inflammation - Follicular (TF) prevalence following at least 5 years of mass azithromycin distribution to discontinuation or continuation of 3 additional years of annual mass azithromycin distribution.
