After baseline surveys demonstrated that Sudan was endemic for trachoma, the Sudan Federal Ministry of Health (FMOH) Trachoma Control Program conducted trachoma prevention and treatment interventions in endemic localities. The Sudan FMOH conducted population-based trachoma prevalence surveys between September 2016 and April 2017 in seven localities across five states of Sudan to document current trachoma prevalence estimates and measure water, sanitation, and hygiene (WASH) indicators. Children aged 1-9 years were examined for five clinical signs of trachoma, and participants of all ages were examined for trachomatous trichiasis (TT). A household questionnaire was administered to gather demographic and WASH-related information. The prevalence of trachomatous inflammation-follicular (TF) in children aged 1-9 years ranged from 0.4% (95% CI: 0.1-1.1%) to 6.4% (95% CI: 3.3-11.9%). Trachomatous trichiasis in those aged 15 years and older ranged from 0.1% (95% CI: 0.0-0.6%) to a high of 4.4% (95% CI: 2.1-9.1%). Of seven localities surveyed, four localities had achieved the elimination threshold of less than 5% TF in children aged 1-9 years. Six localities still required interventions to achieve less than 0.2% TT in those aged 15 years and older. The presence of latrine ranged from a low of 10.8% (95% CI: 5.2-21.1%) to 88.4% (CI: 81.5-93.0%) and clean face among children ranged between 69.5% (95% CI: 63.5-75.0%) and 87.5% (95% CI: 81.2-91.9%). These results demonstrate that Sudan is within reach of eliminating trachoma as a public health problem.</p>
