Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Infection with C. Trachomatis has decreased substantially in trachoma endemic areas following repeated annual mass drug administration (MDA) with azithromycin, although not as rapidly as anticipated. The investigators propose to conduct a clinical trial in 52 communities in Kongwa, Tanzania that on average have trachoma infection at 3.5%. The investigators plan that all communities would have annual rounds of MDA if infection is greater than 1% or follicular trachoma (TF) is 5% or more, but half would be randomized to a surveillance and treatment program to identify and treat new families and families who travel after mass treatment. Communities will have MDA stopped if infection is 1% or less, or TF is less than 5%. MDA will be reinstated if infection re-emerges to 6% or more. The proportion of communities that are able to stop mass treatment will be compared in the group of communities randomized to mass treatment plus the newcomer/traveler treatment program compared to the communities randomized to mass treatment alone after 24 months. At the recommendation of the Data Safety and Monitoring Committee in March 2015, thirty eight (38) of the 52 communities identified as being at risk of trachoma re-emergence at 18 months will be surveyed at 30 months. At risk of trachoma re-infection communities have C. trachomatis infection rates less than or equal to 1% or TF \< 5% at the time of the 18 month survey. Surveillance of communities for families that meet the newcomer or traveler status will extend 6 months beyond the 24 month survey to 30 months in the intervention communities only. A survey of sentinel children in the intervention and control communities at 30 months will be conducted to assess the level of trachoma and infection in all 38 communities at risk of trachoma re-emergence.
