To evaluate the utility of a volunteer health development army in conducting population screening for active TB in a rural community in Southern Ethiopia.

A population-based cross-sectional survey was conducted in sixKebeles (the lowest administrative units).Volunteer women community workers led a symptom screening program to identify adults ≥15 years with TB in the community. Individuals with cough ≥ 2 weeks had spot and morning sputum samples and were examined using AFB smear microscopy, culture and Xpert MTB/RIF.

All 24,517 adults in the study area had a symptom screen performed; 544 (2.2%) had cough ≥ 2 weeks. Among a positive symptom screen, 13 (2.4%) had a positive sputum AFB smear microscopy, 13 (2.4%) a positive culture and 32 (5.8%) a positive Xpert MTB/RIF test. Overall, 34 TB cases (6%) were identified by culture and/or Xpert which corresponds to a prevalence of 139 per 100,000 persons.

We demonstrate the capability of community health workers (volunteer and paid) to rapidly conduct a large-scale population TB screening evaluation and highlight the high yield of such a program to detect previously undiagnosed cases when combined with Xpert MTB/RIF testing. This could be a model to implement in other similar settings.
