Abstract：Objective To analyze the epidemiology and temporal-spatial clustering of other infectious diarrhea in Jinan City from 2013 to 2020, and to provide a scientific basis for prevention and control work. Methods The data about other infectious diarrhea diseases in Jinan City during 2013-2020 were downloaded from the Monitoring System for Infectious Diseases in Chinese Information System for Disease Control and Prevention. And descriptive epidemiological methods and spatiotemporal rearrangement scanning statistical methods were used to analyze the epidemic and spatiotemporal distribution characteristics of other infectious diarrhea diseases. Results A total of 72,033 cases were accumulatively reported in Jinan City from 2013 to 2020, with an average annual incidence of 119.19/100,000. Children under five accounted for 42.74% of the total reported cases. Most of the cases were scattered children, accounting for 41.69%. The male-female ratio was 1.21:1. The incidence rate was higher in males than in females, showing a statistically significant difference (χ2=432.25, P<0.001). There were two incidence peaks in spring and winter in each year. Pingyin County, Tianqiao District, Huaiyin District, Lixia District and Licheng District were the main high incidence areas. Other infectious diarrhea showed positive spatial autocorrelation at the county level with higher Moran's I from 0.039 to 0.235. Spatio-temporal clustering analysisrevealed thatfive space-time clusters were detected(including one first-class cluster and four second-class clusters), with significant spatial and temporal clustering. Conclusion From 2013 to 2020, the epidemic level of other infectious diarrhea diseases in Jinan City showed an upward trend year by year, with significant temporal and spatial aggregation. According to the spatial and temporal distribution and epidemiological characteristics, etiological surveillance should be strengthened, and prevention and control measures such as publicity and education should be carried out among key populations in high incidence areas.
