Trachoma is a blinding disease caused by repeated conjunctival infection with different Chlamydia trachomatis (Ct) genovars. Ct B genovars have been associated with more severe trachoma symptoms. Here, we investigated associations between Ct genovars and bacterial loads in ocular samples from two distinct geographical locations in Africa, which are currently unclear.

Article Synopsis
- - Trichiasis, where eyelashes touch the eye, can lead to blindness, making accurate prevalence data across affected regions essential for resource distribution.
- - A study collected district-level data from 44 countries, refining estimates using the most reliable sources, standardizing for age and sex, and incorporating expert assessments when data was scarce.
- - The 2016 global trichiasis estimate was 2.8 million cases, lower than earlier figures due to improved data quality, enhanced management services, and declines in active trachoma incidence.
Purpose: To estimate the proportion of children with trachomatous inflammation-follicular (TF) and adults with trachomatous trichiasis (TT) in internally displaced persons (IDP) camps in the Darfur States of Sudan and to evaluate associated risk factors.
Methods: IDP camps were identified from government census data. We conducted a subanalysis of data collected in these camps during 2014-2015 as part of surveys covering 37 districts of the Darfur States within the Global Trachoma Mapping Project.
Background: Whilst previous work has identified clustering of the active trachoma sign "trachomatous inflammation-follicular" (TF), there is limited understanding of the spatial structure of trachomatous trichiasis (TT), the rarer, end-stage, blinding form of disease. Here we use community-level TF prevalence, information on access to water and sanitation, and large-scale environmental and socio-economic indicators to model the spatial variation in community-level TT prevalence in Benin, Cote d'Ivoire, DRC, Guinea, Ethiopia, Malawi, Mozambique, Nigeria, Sudan and Uganda.
Methods: We fit binomial mixed models, with community-level random effects, separately for each country.
Purpose: To complete the baseline trachoma map of Sudan by estimating the prevalence of trachoma and associated risk factors in the five Darfur States and Khartoum State.
Methods: Using a standardized methodology developed for the Global Trachoma Mapping Project, we undertook a cross sectional, community-based survey in each of 32 evaluation units (EUs) covering all accessible districts.
Results: We enumerated a total of 84,568 individuals, with 73,489 people (86.
