Abstract:

Objective: To analyze the spatial distribution characteristics of pulmonary tuberculosis (PTB) cases in Hefei City from 2009 to 2020. Methods: The information of 42681 PTB patients who were recorded in The TB Management Information System (a sub-system of the China Disease Prevention and Control Information System) in Hefei City from 2009 to 2020 was obtained. A case spatial distribution map of the street/township level was drawn with GeoDa and Arcgis 10.8 spatial analysis software, to explore the spatial distribution pattern and cold/hot spot areas of PTB. Results: A total of 42681 PTB cases were notified in Hefei City from 2009 to 2020, the incidence decreased from 57.96/100000 (4195/7237966) in 2009 to 31.04/100000 (2908/9369881) in 2020 and showed a fluctuating decreasing trend ($\chi _{\text{trend}}^{2}$=12.531,P<0.001). The result of global spatial autocorrelation analysis showed that there was spatial autocorrelation of PTB incidence in Hefei City from 2009 to 2014, the Moran’s I values were all greater than 0, P values were all <0.05. The spatial distribution from 2015 to 2020 trended to be random. Local autocorrelation analysis showed that the high-high clustered incidences were mainly concentrated in Changfeng County and Feidong County. Low-low clustered areas were mainly concentrated in the main urban areas (Luyang District, Baohe District). The analysis of cold/hot spot showed that there were two hot spots, which were distributed in Yijing township of Changfeng County and Yandian Township of Feixi County. Conclusion: The PTB epidemic in Hefei City has a certain degree of aggregation, so different prevention and control measures should be taken according to characteristics of different counties, districts, streets and towns, and the prevention and control efforts should be strengthened in the high-high clustered streets and hot spot areas.
