An intervention check will also be done by collecting data on knowledge attitude and practices (KAP) of prisoners in the intervention sites using a standardized pre-tested KAP questionnaire through a face-to-face interview by trained prison nurses. Inmate peer educators will be involved in facilitating and interviewing of the baseline data, but the post-test will be performed by trained nurses only. Briefly, the KAP questionnaire will consist of questions on the etiology of TB, mode of transmission, prevention and on attitudes of prisoners such as whether they are afraid to get infected with TB bacilli or not. A sample of prisoners will be selected randomly with proportional allocation of the total number of prisoners in each intervention site and data on their KAP score will be assessed at baseline and the end of the intervention (after 12 months). Only prisoners that will be available in prisons during the intervention period will be eligible for the random selection. Finally, data will also be collected from the randomly selected prisoners from the control sites and the KAP scores of the two groups will be compared.
