Abstract:

Objective: To systematically description and analyze the epidemiological characteristics of reported cases of pulmonary tuberculosis (TB) in China from 1997 to 2023, and to provide scientific evidences for development and improvement of TB prevention and control strategies in China. Methods: The incidence data of pulmonary TB from 1997 to 2023 were collected from the National Epidemic Data Collection, Disease Surveillance and Statistics Report, and Infectious Disease Reporting Information Management System. The temporal and spatial trends of reported incidence of pulmonary TB in the whole country and various regions, the distribution characteristics of different gender, age and occupation group,and the positive rate of etiology in TB patients were analyzed. Results: From 1997 to 2023, a total of 21.9066 million pulmonary TB cases were reported in China, increasing from 418234 in 1997 to 1259308 in 2005, and then decreasing to 613091 in 2023. From 2005 to 2023, the reported incidence rate of pulmonary TB showed an decreasing trend (AAPC=-4.78%, 95%CI: -5.44% to -4.13%, P<0.001), and the decline was slower in the western region (AAPC=-4.42%, 95%CI: -5.77% to -2.89%, P<0.001). From 1997 to 2023, the male-to-female ratio of reported TB cases in China was 2.22∶1, the proportion of children younger than 15 years showed a decreasing trend (AAPC=-5.74%, 95%CI: -6.01% to -5.50%, P<0.001), and the proportion of elderly aged ≥65 years showed an increasing trend (AAPC=3.80%, 95%CI: 3.61% to 3.99%, P<0.001). The top five occupations reporting the number of cases were farmers, animal keepers and fishermen (61.50%,13421197/21822416), homemakers and unemployed persons (9.32%,2033078/21822416), workers (5.89%,1285335/21822416), students (5.44%,1186104/21822416) and retired persons (4.69%,1022406/21822416). The etiological positive rate of reported TB patients in 2023 was 67.08%(392569/585187). Conclusion: Since 1997, the reported incidence of pulmonary TB in China increased first and then decreased, reflecting the effect of effective TB prevention and control measures in different periods. In the future, different strategies should be implemented according to the epidemic characteristics of TB in different regions and populations, and the application of new technologies and measures should be promoted to accelerate the end of the TB epidemic.
