Abstract: Objective: To investigate the knowledge of tuberculosis (TB) infection control among newly diagnosed etiologically positive pulmonary TB patients, and to provide basis for effective TB infection control and health education. Methods: From January 2019 to January 2023, 196 newly diagnosed TB patients with positive etiological test results from Beijing Chest Hospital, Capital Medical University, Tuberculosis Prevention and Control Institute of Changping District, Disease Prevention and Control Center of Daxing District in Beijing were investigated with a questionnaire on knowledge about TB infection control, including basic information of patients, TB infection control questionnaire, clinical information, etc.; 196 questionnaires were sent out, with 196 valid questionnaires and a 100.0% effective rate. Then we summarized the knowledge of TB infection control among respondents, and analyzed the factors affecting their awareness of core information of TB prevention and control. Results: The total awareness rate among the surveyed subjects was 64.4% (2649/4116). Multivariable logistic regression showed that compared to those with junior high school or lower education, those with a college/undergraduate degree or above were more likely to meet the standard of TB infection control knowledge (OR=6.659, 95%CI: 1.995-22.220); compared with those with TB contact history, those without were less likely to reach the TB infection control knowledge standard (OR=0.218, 95%CI: 0.054-0.886). Conclusion: The awareness of TB infection control knowledge among newly diagnosed etiologically positive pulmonary TB patients still needs to be improved, and the awareness of those with junior high school education and below and those without TB contact history are relatively low, on whom targeted TB prevention and control health education should be performed in the future.
