Factors affecting tuberculosis (TB) prevention behaviors among household contacts in Phitsanulok Province, northern Thailand: implications for TB prevention strategy plan

Household contacts to pulmonary tuberculosis should be educated about the perceived self-efficacy of tuberculosis prevention, and receive more social support to prevent the disease. The focus should be on current smokers, those who drive to the hospital, those who do not know the history of tuberculosis vaccination, and relatives of patients (older sibling, aunt, uncle, younger sibling, nephew) to reduce the risk of pulmonary tuberculosis in the future.
