AB  - BACKGROUND: Trachoma prevalence surveys provide the evidence base for district 
      and community-wide implementation of the SAFE strategy, and are used to evaluate 
      the impact of trachoma control interventions. An economic analysis was performed 
      to estimate the cost of trachoma prevalence surveys conducted between 2006 and 
      2010 from 8 national trachoma control programs in Africa. METHODOLOGY AND 
      FINDINGS: Data were collected retrospectively from reports for 165 districts 
      surveyed for trachoma prevalence using a cluster random sampling methodology in 
      Ethiopia, Ghana, Mali, Niger, Nigeria, Sudan, Southern Sudan and The Gambia. The 
      median cost per district survey was $4,784 (inter-quartile range 
      [IQR] = $3,508-$6,650) while the median cost per cluster was $311 
      (IQR = $119-$393). Analysis by cost categories (personnel, transportation, 
      supplies and other) and cost activity (training, field work, supervision and data 
      entry) revealed that the main cost drivers were personnel and transportation 
      during field work. CONCLUSION: Population-based cluster random surveys are used 
      to provide the evidence base to set objectives and determine when elimination 
      targets have been reached for several neglected tropical diseases, including 
      trachoma. The cost of conducting epidemiologically rigorous prevalence surveys 
      should not be a barrier to program implementation or evaluation.
