摘要Tuberculosis(TB),one of the oldest infectious diseases caused by Mycobacterium tuberculosis,poses a considerable challenge to global public health.There are approximately 10 million new TB cases worldwide annually,and TB claims the lives of nearly 3 million people each year,making it one of the leading causes of death from a single infectious disease[1].China ranks third globally in terms of TB burden,with approximately 733,000 TB cases reported in 2023[2].Based on the ecological model of health determinants developed by Whitehead and Dahlgren,health determinants can be classified into direct causes,such as disease-specific causes or individual influencing factors,and indirect causes,such as social determinants or environmental factors.Jiangsu Province,located on the southeastern coast of China,has reported approximately 20,000 cases of TB annually in recent years,and significant spatiotemporal heterogeneity because of non-medical determinants has contributed to variation in TB incidence across counties.Previous studies examined the factors influencing TB and its temporal and spatial disparities to improve healthcare allocation and management[3].
