Description: In districts with endemic trachoma, the World Health Organization (WHO) recommends mass azithromycin distribution to the entire community. However, transmission of ocular strains of Chlamydia trachomatis is greatest among preschool-aged children, and targeting drug distribution to these groups may conserve resources and limit the risk of antimicrobial resistance. This cluster-randomized clinical trial investigated the efficacy of biannual mass azithromycin distribution to children ages 1 to 59 months as a strategy for trachoma elimination in the hypoendemic setting of rural Niger.
