Objective  To analyze the epidemiological characteristics and change trend of other infectious diarrheal diseases in Yubei district of Chongqing, and provide evidence for the prevention and control of other infectious diarrheal disease.

Methods  The incidence data of of other infectious diarrheal disease in Yubei during 2015−2023 were collected from the infectious disease surveillance and reporting system of China Disease Prevention and Control Information System. Descriptive epidemiological method, Joinpoint regression model and spatial autocorrelation analysis were used to analyze the epidemiological characteristics of other infectious diarrheal diseases in Yubei.

Results  A total of 29 455 cases of other infectious diarrheal diseases were reported in Yube from 2015 to 2023, with an average annual incidence of 180.68/100 000. The reported cases were mainly children living scatteredly under 3 years old, and the reported cases mainly occurred in winter and spring. Longxi, Renhe and Yuanyang communities were the areas with high incidences. The incidence trend analysis showed that the reported incidence of other infectious diarrheal diseases in Yubei increased from 2015 to 2017, with an average annual percent change (APC) of 17.94% 95% confidence interval (CI): 0.33%−37.84% and decreased from 2017 to 2023, with an APC of −6.86% (95% CI: −15.17%− −3.96%) . The age group specific analysis indicated that the incidence rate in age group 7~10 year increased with an APC of 11.22%（95%CI: 5.51%−19.72%）), and the incidence rate in age groups 10−65 years and ≥ 65 years decreased with APCs of −4.27% (95%CI: −6.45%− −1.96%) and −10.68% (95%CI: −17.87%− −2.98%). Spatial autocorrelation analysis showed that the clustering areas of other infectious diarrheal diseases increased in Yubei from 2015 to 2023, and the spatial dependence was more obvious, and the high-high clustering area gradually shifted from Longshan and Longxi communities to Lijia and Yuelai communities.

Conclusion  The average annual reported incidence of other infectious diarrheal diseases in Yubei was higher than that in most regions in China from 2015 to 2023. It is necessary to to take targeted measures to control the spread of other infectious diarrhea diseases in key populations and key areas based on the seasonality of the disease.
