<![CDATA[One way of transmitting pulmonary Tuberculosis is through droplets of phlegm (droplet nuclei) when a patient coughs or sneezes, especially to those closest to the patient, namely the family who lives in the same house as the patient. Family behavior in prevention plays an important role in reducing the risk of pulmonary TB transmission, such as using eating or drinking utensils simultaneously, lack of lighting in the house, and patients still spitting carelessly. The purpose of this study was to determine the relationship between the level of family knowledge and the prevention of transmission of pulmonary tuberculosis in the work area of the Pahandut Health Center.
