Analysis of notifiable infectious diseases in Sichuan Province in 2023
Objective To analyze the epidemic characteristics of notifiable infectious diseases reported in Sichuan Province in 2023,and to provide scientific basis for infectious disease prevention and control.Methods The incidence data of Class A,B and C infectious diseases in Sichuan Province from January 1,2018 to December 31,2023 in the Infectious Disease Monitoring System were analyzed,and Excel 2013 software was used to establish a database.Descriptive research methods were used to describe the incidence and mortality profile and epidemiological characteristics of infectious diseases in Sichuan Province in 2023.Compared with the incidence situation from 2018 to 2022,the relative number was calculated to analyze the changing trend of the incidence.The comparison of rates was conducted by SPSS 20.0 software with Chi-square test,and the test level was α=0.05.Count data were represented by rate and composition ratio,and the average was calculated by arithmetic mean.Results In 2023,Sichuan Province reported 2 cases of Class A infectious diseases,32 kinds of Class B and Class C infectious diseases(1 649 785 cases),and the incidence rate was 614.04/105 and 1 356.13/105,respectively.The top three diseases of Class B infectious diseases were CO VID-19,hepatitis B and syphilis.Influenza,hand-foot-mouth disease and other infectious diarrhea diseases ranked the top three in the incidence of Class C infectious diseases.The incidence of Class B infectious diseases had a peak in May,while Class C infectious diseases had two peaks in March and December,respectively.The male-to-female sex ratio of the reported incidence rate of Class B infectious diseases was 1.10∶1,and farmers had the largest number of cases.The male-to-female sex ratio of the incidence of Class C infectious diseases was 1.08∶1,and most cases were students and nursery children.The incidence rates of key diseases such as CO VID-19,influenza and hand-foot-mouth disease in different age groups and different regions were different,and the differences were statistically significant(all P＜0.001).Conclusions In 2023,the incidence rate of notifiable infectious diseases in Sichuan Province showed an overall upward trend,among which,influenza,CO VID-19,hand-foot-mouth disease,etc.increased rapidly and had an obvious time distribution.Close monitoring should be carried out and prevention and control work should be focused on.
