Abstract Objective To investigate the epidemiological characteristics of other infectious diarrhea (OID) in Huzhou City, Zhejiang Province from 2013 to 2023, so as to provide the basis for formulating of prevention and control measures for OID. Methods Data of OID in Huzhou City from 2013 to 2023 were collected from the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. Epidemiological and etiological characteristics of OID cases were analyzed using a descriptive epidemiological method. Results A total of 111 455 cases of OID were reported in Huzhou City from 2013 to 2023, with an average annual reported incidence of 331.82/105, showing a decreasing trend (P<0.05). The peak incidence of OID was reported from July to August and from November to February of the following year, primarily due to bacterial and viral pathogens, respectively. Changxing County had the highest reported incidence of OID (660.62/105), while Anji County had the lowest (188.92/105). Among the reported cases, 58 259 were male and 53 196 were female, with a male-to-female ratio of 1.10∶1. The highest incidence was observed in children aged under 1 year (4 545.70/105). The majority of cases were scattered children, with 36 933 cases (33.14%). There were 22 639 cases with clear pathogens, and rotavirus was the most common, with 16 953 cases (74.88%). Conclusions The overall incidence of OID in Huzhou City showed a decreasing trend from 2013 to 2023. OID peaked in summer and winter and was primarily observed in children aged 1 year below and scattered children. Rotavirus infection was the dominant etiology.
