This form should be used to document evidence needed to include in trachoma elimination dossiers. It should be considered and conducted while programs transition into routine services.
This study analyzes data from nine trachoma-endemic populations and provides operational thresholds for the interpretation of serological data in low-transmission and post-elimination settings.
This document presents (i) the principles important to the design of trachoma prevalence surveys conducted after interventions intended to eliminate the disease as a public health problem, and (ii) WHO recommendations for their implementation.
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.
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.
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.
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.
The findings from this survey indicate elimination thresholds have been maintained in Ghana in 17 of the 18 surveyed evaluation units. Only one evaluation unit, Yendi, did not achieve the TT elimination threshold.
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
