Abstract

Latent tuberculosis infection (LTBI) is a inactive stage after being infected with Mycobacterium tuberculosis and it reactivates into pulmonary tuberculosis (PTB). This study was to estimate the prevalence of LTBI in homeless persons staying in 13 shelters run by NGOs in Chennai metro city, India. A cross-sectional survey was conducted from January to April 2018. All inmates aged 15 years and above were screened for PTB infection using tuberculin skin test (TST) and disease smear and culture examinations. Out of a total of 1,068 registered, 1,016 persons were screened for PTB disease and 818 persons for LTBI. Among them, PTB was detected in two persons and TST was positive in 275 persons. Univariate and multivariate analyses were performed to find out the factors associated with LTBI. It was found that LTBI is significantly associated with male gender, aged more than 40 years and with chest X-ray TB lesions. This study finding highlights that low prevalence of TB disease and one third of homeless persons infected with tuberculosis. Our finding suggests that there is a need for prevention interventions to eliminate TB in this key population
