Trachoma prevalence remains below threshold in five districts after stopping mass drug administration: results of five surveillance surveys within a hyperendemic setting in Amhara, Ethiopia

In a trachoma hyperendemic region, a TF prevalence <5% was successfully maintained in five districts for ≥2 years after stopping MDA. MDA is still not warranted for these districts, however, the S, F and E components of the SAFE strategy should continue.

Longitudinal change in the serology of antibodies to Chlamydia trachomatis pgp3 in children residing in a trachoma area

The aims of this study are to determine the rates of seroconversion, and seroreversion (if any), in connection with trachoma and infection in a random sample of children age 1–9 years over a one year period in 50 communities in Kongwa Tanzania, where trachoma was formerly hyper-endemic.

Conjunctival transcriptome profiling of Solomon Islanders with active trachoma in the absence of Chlamydia trachomatis infection

This article sets out to characterise patterns of gene expression at the conjunctivae of children in these provinces with and without clinical signs of trachomatous inflammation-follicular (TF) and C. trachomatis infection.

Population-based coverage survey results following the mass drug administration of azithromycin for the treatment of trachoma in Amhara, Ethiopia

This coverage survey was conducted as part of an ongoing monitoring strategy within the Amhara Trachoma Control Program. The Carter Center provided the Amhara Regional Health Bureau with support to implement MDA, and separately, also funded, designed and executed this survey in collaboration with the Regional Health Bureau.

Surveillance surveys for reemergent trachoma in formerly endemic districts in Nepal From 2 to 10 years after mass drug administration cessation

This study analyzes whether the World Health Organization recommendation for surveillance surveys to be done 2 years after cessation of mass drug administration in districts formerly endemic for trachoma is sufficient to detect reemergence of disease

Trachoma in the Democratic Republic of the Congo: Results of 46 baseline prevalence surveys conducted with the Global Trachoma Mapping Project.

Trachoma was suspected to be endemic in parts of the Democratic Republic of the Congo (DRC). This study aimed to estimate prevalences of trachomatous inflammation-follicular (TF), trichiasis, and water and sanitation (WASH) indicators in suspected-endemic Health Zones.
