Title: Tripartite International Research for the Elimination of Trachoma
Brief Summary: Mass antimicrobial administrations have been remarkably successful in reducing the prevalence of the ocular strains of Chlamydia that cause trachoma. Repeated distributions progressively lower the prevalence of infection, and in some cases may even result in local elimination. Mass treatments cannot be continued forever, due to concerns about cost and antibiotic resistance. The hope has been that other measures such as latrine construction and hygiene programs would prevent infection from returning. Unfortunately, no non-antibiotic measure has yet demonstrated an effect on infection.

1. We hypothesize that Chlamydial infection will return to communities when treatment ends.
2. We hypothesize that infection will be completely eliminated in all communities treated for seven years.
3. We hypothesize that identifying and treating clinically active cases among preschool aged children will delay or even prevent reemergence at a far lower cost than mass treatment of all individuals.
