This study undertaken in 2015 was carried out to estimate the prevalence of trachoma and access to water and sanitation in seven suspected-trachoma-endemic districts in northern Congo, and thereby determine whether trachoma is a public health problem requiring intervention. The study considered the seven districts as a single evaluation unit, and used the standardised methodologies of the Global Trachoma Mapping Project.
The results concluded that trachoma is not a public health problem in this part of Congo. No examined individual had trichiasis and the age-adjusted prevalence of trachomatous inflammation—follicular (TF) was only 2.5% (less than the <5% WHO TF elimination threshold). The WASH component of the survey concluded that access to water and sanitation is inadequate in this part of Congo.
