Epidemiological characteristics of other infectious diarrhea and secular variation trends of their incidence rates in Fuling District of Chongqing Municipality,2013-2022
Objective To analyze the epidemiological features of other infectious diarrhea and long-term changing trends of their incidence rates in Fuling District of Chongqing Municipality from 2013 to 2022,and to provide a scientific basis for other infectious diarrhea prevention and control in Fuling District.Methods Data about other infectious diarrhea cases in Fuling District from 2013 to 2022 were collected from the China Information System for Disease Prevention and Control,and the time,regional and population distribution was analyzed through descriptive research.ArcMap 10.7 was used to draw point density map to visualize the regional distribution of the incidence.Excel 2019 and SPSS 20.0 were applied to calculating the age-standardized incidence rate of the Chinese population.Joinpoint regression model was employed to calculate annual percent of change(APC)and average annual percent change(AAPC),and then the long-term changing trends of the incidence rates were analyzed.Results A total of 11,380 cases of other infectious diarrhea were reported in Fuling District from 2013 to 2022,with the average annual reported incidence of 1,138 cases and the average annual reported incidence rate of 100.87/100,000.There were two incidence peaks in winter and summer.In the population distribution,the number of reported cases in males(n=6,359)was higher than that in females(n=5,021),the number of reported cases in 0-3 years old was 9,995(accounting for 87.83％).As for the population classification,most of the cases were scattered children(n=9,797,86.09％).As for the regional distribution,the cases were mainly distributed in Lizhi Street(n=2,485,21.84％),Chongyi Street(n=2,355,20.69％),Dunren Street(n=2,119,18.62％),Ma'an Street(n=1,313,11.54％)and Jiangdong Street(n=380,3.34％).One outbreak was reported,which occurred in a primary school.Joinpoint regression analysis revealed that the overall trend of the age-standardized incidence rates in Fuling District from 2013 to 2022 showed an increasing trend,with statistical significant differences in the trend(AAPC=8.50％,95％CI:3.98-13.22,P=0.002).The crude incidence rates of other infectious diarrhea in Fuling District from 2013 to 2018 presented an upward trend,with statistical significant differences in the trend(APC=16.75％,95％CI:2.73-32.69,P=0.026),but the crude incidence rates from 2018 to 2022 showed a decreasing trend,without statistical significant differences in the trend(APC=-9.89％,95％CI:-24.81-7.98,P=0.199).Conclusion Other infectious diarrhea in Fuling District during 2013-2022 mainly affected scattered children,and the incidence peak in winter was higher than that in summer.Most of the cases were scattered in the urban areas like Lizhi Street,Chongyi Street and Dunren Street,and schools(primary schools)were the high incidence places.The overall trend in the incidence of other infectious diarrhea in Fuling District from 2013 to 2022 showed a significant increasing trend,but the crude incidence rates from 2018 to 2022 showed a certain decreasing trend under the influence of the SARS-CoV-2 pandemic.Based on the epidemiological characteristics of other infectious diarrhea in Fuling District,targeted prevention and control measures should be taken for high incidence populations in different seasons and regions.
