Previous phases of trachoma mapping in Pakistan completed baseline surveys in 38 districts. To help guide national trachoma elimination planning, this work was carried out to estimate trachoma prevalence in 43 suspected-endemic evaluation units (EUs) of 15 further districts. A population-based trachoma prevalence survey was planned for each EU. Two-stage cluster sampling was employed, using the systems and approaches of the Global Trachoma Mapping Project.
