RecruitingBehavioural interventionEconomic Incentives and vDOT for Latent Tuberculosis InfectionThe purpose of this study is to evaluate a novel and scalable intervention that combines Video Directly Observed Therapy (vDOT) and financial incentives to promote completion of treatment for latent tuberculosis. Adult participants who are initiating treatment for latent tuberculosis will be recruited from the Baltimore City Health Department. The primary hypothesis is that the incentive intervention will increase the percentage of participants that complete the treatment for latent tuberculosis above the completion rates of participants receiving usual care.
