Analysis of the registered incidence of pulmonary tuberculosis in Wuhan, China, 2011—2020

Objective To investigate the registered incidence and distribution characteristics of pulmonary tuberculosis in Wuhan, China, from 2011 to 2020, and provide a basis for scientific formulation of tuberculosis prevention and treatment measures.

Methods A descriptive statistical analysis was performed on the medical records of patients with pulmonary tuberculosis who were registered in Wuhan from 2011 to 2020 through the National Tuberculosis Information Management System.

Results A total of 61 353 cases of pulmonary tuberculosis were registered in Wuhan, with a mean annual incidence rate of 56.96/100 000 from 2011 to 2020. There was a tendency of reduction in the number of pulmonary tuberculosis cases and the incidence rate of pulmonary tuberculosis over these years, and there was a significant difference in the changing trend of incidence rate among different years (χ_trend²=852.67, P < 0.001). The incidence rate of pulmonary tuberculosis in 2020 was reduced by 37.72% compared with that in 2011, with a mean annual reduction rate of 5.13%. The epidemic peak was observed from March to May. Male individuals tended to have a higher incidence rate than female individuals(82.54/100 000 vs 37.89/100 000), and individuals aged 80-84 years had the highest incidence rate(148.22/100 000).

Conclusion The registered incidence of pulmonary tuberculosis tends to decrease in Wuhan, with relatively fixed populations and areas. In the future, pulmonary tuberculosis prevention and control should be conducted with an emphasis on related key points based on the distribution characteristics of epidemic situation in accordance with time and place.
