To analyze the incidence rate, spatial trends and clustering characteristics of the echinococcosis in Tibet Autonomous Region from 2019 to 2023, with the aim of providing a scientific basis for the formulation of targeted prevention and control strategies.
Utilizing the echinococcosis surveillance data from Tibet Autonomous Region between 2019 and 2023, χ2 tests were conducted using SPSS 25.0 software to compare differences between groups. ArcGIS 10.8 software was used for spatial trend surface analysis and spatial autocorrelation analysis.
From 2019 to 2023, a total of 508 074 individuals were screened in Tibet Autonomous Region, with 460 new cases of echinococcosis identified, resulting in an annual average incidence rate of 0.091%. Significant differences in incidence rates were observed between different years and regions. Spatial trend analysis revealed a higher incidence in the west and lower in the east, with a higher incidence in the middle and lower incidence at both ends in the north-south direction. Spatial autocorrelation analysis indicated that high-high clustering areas were concentrated in southwestern Tibet, while low-low clustering areas were concentrated in central and southern Tibet.
From 2019 to 2023, the incidence of echinococcosis in Tibet Autonomous Region exhibited significant spatial trends and clustering characteristics. It is recommended to strengthen surveillance in southwestern Tibet, assess the epidemiological situation, and explore prevention and control models suitable for this region to reduce the high incidence of echinococcosis.
