Abstract
Background and challenges to implementation: Nation- al TB Prevalence Surveys (TBPS) provide valuable in- formation to policy makers and National TB Programs about TB burden and missing cases. However, TBPS can be challenging, especially in TB-endemic low- and middle-income countries (LMICs).
Intervention or response: We reviewed 28 World Health Organisation (WHO) TBPS reports from Asia (n=14) and sub-Saharan Africa (n=14), published after 2000. All surveys were population based and followed WHO guidance. All surveys used a TB symptom screening questionnaire and chest radiograph to identify people with suspected TB disease. Acid Fast Bacilli (AFB) smear (25/28, 89%), fluorescence microscopy (17/28, 61%), and mycobacterial culture (27/28, 96%) were used to diagnosed TB, with most post-2010 surveys also using GeneXpert (14/28, 50%).
Results/Impact: Several domains of TBPS challenges were identified and are summarized in Table 1. They included:
1) under-recruitment in urban settings (4/28, 14%) and exclusion of
