Effect of a single mass antibiotic distribution on the prevalence of infectious trachoma

A study was conducted to determine whether ocular chlamydial infection returns to the community up to 24 months after a single mass antibiotic distribution in a hypernedemic region of Ethiopia. The findings showed that ocular chlamydial infection was not eliminated in children aged 1 to 5 years after a single mass azithromycin distribution, slowly returning over 24 months and repeated treatments or other effective measures would be necessary for elimination.
