Brief Summary
This study is designed as a cluster-randomized trial. The cluster unit is at the community level. Communities will be randomized to 1 of 2 study arms: DOTS+ACF or DOTS. Communities in the DOTS+ACF arm will receive door-to-door symptom screening of the entire population by health care workers between 2 and 4 times over a 9-month period. Those communities in the DOTS-arm will receive the current standard of care in those communities (PCF). All study communities will be receiving between 4 and 6 visits by community health workers annually as part of a program to assess and follow-up illnesses in each household. Households with ill residents will be visited more often. The intervention for this study is simply adding 3 to 5 simple questions to the current protocol. For subjects responding positively to these questions, results will be returned to the subject at their home and routine, standard of care follow-up diagnostic and treatment algorithms will be followed.
