Abstract

Abstract:

Objective: To examine the epidemiological trends and characteristics of pulmonary tuberculosis (PTB) in Zhuxi County, Shiyan City, over a ten-year period (2014-2023) and to provide scientific evidence to guide PTB prevention and control efforts. Methods: Data on PTB cases registered in Zhuxi County from 2014 to 2023 were retrieved from the “Tuberculosis Information Management System,” a component of the “Chinese Disease Prevention and Control Information System.” Collected variables included demographic characteristics, case detection methods, and etiological findings. Descriptive epidemiological methods were used to analyze the data. Results: From 2014 to 2023, a total of 2210 PTB cases were registered in Zhuxi County, comprising 1147 pathogen-positive cases (51.90%) and 1063 pathogen-negative cases (48.10%). The average annual registration rate was 72.42/100000, demonstrating a significant overall decline over the study period ($\chi_{\text {ternd }}^{2}$ end=6.104, P<0.01), with an average annual reduction rate of 2.25%. The majority of cases (97.56%, 2156/2210) were identified through symptomatic presentations and subsequent medical consultations. Seasonal variations were observed, with December recording the highest number of registrations (11.00%, 243/2210) and January the lowest (5.38%, 119/2210). The highest annual registration rate for tuberculosis was observed in Yingying Town, with 92.82/100000 (106 cases in total). Among the registered patients, the male-to-female ratio was 3.34∶1 (1701/509). The average annual registration rate for males was 108.54/100000, significantly higher than that for females at 34.36/100000 (χ²=575.217, P<0.01). Age distribution analysis revealed that individuals aged 0-14 years accounted for 1.26% (28/2210) of the cases, those aged 15-64 years constituted 81.48% (1801/2210), and individuals aged 65 years and older comprised 17.24% (381/2210). Occupationally, the majority of patients were farmers (85.66%, 1893/2210), followed by students (4.75%, 105/2210). Conclusion: The prevention and control of PTB in Zhuxi County remain a significant public health challenge. Tailored, comprehensive measures should be implemented based on local epidemiological conditions to enhance tuberculosis prevention and management, particularly in high-burden areas and among at-risk populations.
