A cross-sectional study was conducted to evaluate the prevalence of latent tuberculosis infection and feasibility of TB preventive therapy among Thai prisoners. Researchers performed a cross-sectional study among prisoners in Klong Prem Central Prison, Bangkok. Individuals were screened for active TB by questionnaire and chest x-ray. They assessed latent TB infection (LTBI) by Tuberculin skin test and QuantiFERON-TB Gold Plus among subgroups. The study enrolled a total of 1,002 participants between August 2018 and November 2019.
