Abstract

Background

Tuberculosis (TB) remains a critical public health challenge in China, particularly amid rapid urbanization and internal migration. This retrospective study analyzed the epidemiology and transmission dynamics of TB among internal migrants (IMTB) versus local residents (LRTB) in Hangzhou, China, from 2013 to 2022.

Methods

Data from 47,659 pulmonary TB cases were extracted from the national Tuberculosis Information Management System.

Results

IMTB accounted for 21.88 % of cases, with patients significantly younger (mean age 33.45 vs. 51.50 years, P < 0.0001) and fewer bacteriologically confirmed diagnoses (34.9 % vs. 41.8 %, P < 0.0001) compared to LRTB. Treatment success rates were higher among IMTB (95.0 % vs. 89.7 %, P < 0.0001). Spatial clustering of IMTB occurred in industrial districts, primarily originating from Anhui, Guizhou, and Jiangxi provinces.

Conclusion

Migration-driven TB transmission highlights the need for adaptive control strategies in urbanizing settings.

2013 - 2022年杭州市流动人口结核病流行病学及传播动态回顾性分析

结核病（TB）在中国仍然是一个重大的公共卫生挑战，特别是在快速城市化和内部移民的背景下。本回顾性研究分析了2013年至2022年中国杭州内部流动人口（IMTB）与当地居民（LRTB）之间结核病的流行病学和传播动态。方法从国家结核病信息管理系统中提取47,659例肺结核病例的数据。结果simtb占21.88%，患者年龄明显年轻化（平均年龄33.45岁vs. 51.50岁）；0.0001)和较少的细菌学确诊(34.9%比41.8%,P <；0.0001)与LRTB相比。IMTB的治疗成功率更高(95.0% vs 89.7%, P <；0.0001)。IMTB的空间集聚主要集中在工业区域，主要分布在安徽、贵州和江西等省。结论移民驱动的结核病传播突出了城市化环境下自适应控制策略的必要性。
