Abstract：OBJECTIVE To analyze the epidemiological characteristics and pathogen composition of infectious diarrhea cases in Qidong from 2022 to 2023,providing a theoretical basis for the formulation of disease prevention and control policies.METHODS Surveillance data on diarrhea cases from various sentinel sites in Qidong from 2022 to 2023 were collected.Pathogen testing was conducted on stool samples,and the epidemiological characteristics were analyzed.RESULTS A total of 1 090 infectious diarrhea cases were monitored from 2022 to 2023,with the highest proportion(26.33%,287/1 090)occurring among children aged 0～4 years.A total of 41 strains of enteropathogenic bacteria(3.76%)and 261 strains of enteric viruses(23.94%)were detected.The primary viral pathogens were norovirus(9.45%,103/1 090)and rotavirus(4.77%,52/1 090),while Salmonella was the leading bacterial pathogen(2.29%,25/1 090).CONCLUSION Infectious diarrhea predominantly affects children under 5 years of age,with notable seasonal patterns,peaking in winter and summer.Strengthened disease prevention efforts are needed,including public education,improved living conditions and habits,and ongoing epidemic surveillance.
