The risk of tuberculosis transmission is highest among household contacts; therefore, the behavior of family members of TB patients plays an important role in preventing transmission. This study aimed to analyze the factors associated with family behavior in preventing tuberculosis transmission in the working area of the Kenali Besar Public Health Center, Alam Barajo District, Jambi City, in 2025.
