目的 了解2013—2023年浙江省台州市椒江区其他感染性腹泻病（OID）的流行趋势及特征,为制定肠道传染病防控策略提供依据。方法 依托中国疾病预防控制信息系统与突发公共卫生事件管理信息系统数据平台,对2013—2023年期间浙江省台州市椒江区OID病例的相关资料进行系统收集,进而深入剖析该区OID的发病动态演变规律及流行病学特征。结果 2013—2023年,椒江区累计报告OID 11 576例,未出现死亡病例,年报告发病率为147.15/10万,整体呈波动下降趋势（P<0.05）;发病高峰集中在7至9月及12月至次年1月,夏季以细菌感染,冬季以病毒感染为主;区域上,大陈镇报告年发病率最高（328.16/10万）,三甲街道最低（92.48/10万）;人群分布中,男性病例6475例,女性病例5101例,<1岁组发病率最高,发病以散居儿童为主;病原学分布中,4127例实验室确诊病例中,674例完成病原学检测,其中轮状病毒最多占55.64%、诺如病毒占19.14%、沙门菌占13.20%、腺病毒占8.61%、其他细菌占2.82%、副溶血性弧菌占0.59%;除8至9月细菌感染比例高于病毒外,其余月份均以病毒感染为主。结论 2013-2023年期间,椒江区OID的总体年发病率呈现逐年波动下降态势,其发病高峰期集中于夏季与冬季两个季节,患者群体主要集中在<1岁年龄组,其中轮状病毒为该区域OID的主要病原类型。

Objective To analyze the epidemic characteristics and trends of other infectious diarrhea (OID) in Jiaojiang District, Taizhou City, Zhejiang Province from 2013 to 2023, providing a basis for formulating of prevention and control measures for OID. Methods By relying on the data platforms of the "China Disease Prevention and Control Information System" and the "Public Health Emergency Management Information System," we systematically collected relevant data on OID cases from 2013 to 2023, and then conducted an in-depth analysis of the dynamic evolution patterns and epidemiological characteristics of intestinal infectious diseases in Jiaojiang District. Results From 2013 to 2023, a total of 11,576 OID cases were reported in Jiaojiang District, with no fatalities recorded. The annual reported incidence rate was 147.15 per 100,000 population, showing a a general danward trend (P < 0.05). The peak incidence periods were concentrated in July-September and December-January of the following year, with bacterial infections predominating in summer and viral infections in winter. Geographically, Dachen Town had the highest incidence rate (328.16/100,000), while Sanjia street had the lowest (92.48/100,000).Among the cases, there were 6475 male cases and 5101 female cases. The incidence rate was the highest in the < 1-year-old group, mainly among scattered children. In terms of etiological distribution, among the 4127 laboratory-confirmed cases, 674 cases completed etiological testing. Among them, rotavirus accounted for the largest proportion at 55.64%, norovirus accounted for 19.14%, Salmonella accounted for 13.12%, adenovirus accounted for 8.61%, other bacteria accounted for 2.82%, and Vibrio parahaemolyticus accounted for 0.59%. Except for August and September when the proportion of bacferial infections was higher than that of viral inefections, viral infections were the main cause in the other months. Conclusion During the period from 2013 to 2023, the overall annual incidence rate of OID in Jiaojiang District showed a fluctuating downward trend year by year. The peak incidence periods were mainly concentrated in summer and winter. The patient group was mainly in the < 1-year-old age group. Among them, Rotavirus was the main pathogen type causing OID in this area.
