Brief Summary

The purpose of this community-based randomized trial was to determine, in trachoma hyper-endemic communities of Tanzania, the added value of intensive spraying to control flies on the fly population and on trachoma and ocular chlamydia infection at 6 months and one year after mass antibiotic treatment.
