Background: We aimed to determine the household distribution and viability of Chlamydia trachomatis (Ct) from the eyes, face, and hands during the initial two visits of a year-long fortnightly cohort study in geographically defined adjacent households.
Methods/findings: We enrolled 298 individuals from 68 neighbouring households in Shashemene Woreda, Oromia, Ethiopia. All individuals above 2 years of age residing in these households were examined for signs of trachoma.

Background: Trachoma is targeted by the World Health Organization (WHO) for elimination as a public health problem by 2030. Trachoma impact surveys using standardised methodology are recommended to monitor progress towards elimination and to determine eligibility for continued surgery, antibiotics, facial cleanliness, and environmental improvement (SAFE) interventions. From 2007 to 2015, four counties of Eastern Equatoria State, South Sudan, received three to five rounds of mass drug administration with antibiotics.

Background: Following interventions to eliminate trachoma in the Afar region of Ethiopia, our goal was to reassess the prevalence of trachomatous trichiasis (TT) and trachomatous inflammation-follicular (TF) at the woreda level, and to identify factors associated with the disease.
Methods: Cross-sectional community-based surveys were conducted in 26 trachoma-endemic woredas, employing a standardized approach. Households were selected as the secondary sampling unit.

Purpose: Baseline surveys were conducted in Tigray region, Ethiopia, in 2013. Since then, rounds of azithromycin mass drug administration (MDA) have been delivered in-line with international guidance. The purpose of these surveys was to assess trachomatous inflammation-follicular (TF) prevalence following those treatments to enable the region to plan the next steps towards elimination of trachoma.

Trachoma recrudescence is a serious concern for trachoma control programs. Programs define recrudescence as the return of trachomatous inflammation-follicular (TF) prevalence above elimination threshold (≥5%) on district-level trachoma surveillance surveys (TSSs). This study aimed to determine potential correlates of trachoma recrudescence within a historically highly endemic region.
