摘要：

目的 分析四川省其他感染性腹泻流行特征及病原谱，为防控工作提供科学依据。方法 通过中国疾病预防控制信息系统获取2019—2023年四川省其他感染性腹泻病例、病原学及突发公共卫生事件（简称事件）相关资料，使用描述性研究方法进行分析。结果 2019—2023年四川省累计报告其他感染性腹泻273 653例，年均报告发病率为65.41/10万，发病率总体呈上升趋势。发病呈双峰分布，高峰分别为2—3月（51 161例，占18.70%）和6—8月（83 419例，占30.48%）。累计报告病例数前3位的市（州）依次是成都市（66 767例）、绵阳市（32 812例）、宜宾市（20 308例）。男性和女性年均报告发病率分别为68.08/10万和62.71/10万，报告病例的年龄主要为≤4岁（156 217例，占57.09%），职业主要为散居儿童（139 372例，占50.93%）。病原学诊断结果明确的病例32 057例，其中86.48%（27 722例）为病毒性腹泻，病原体主要是轮状病毒（21 425例）；12.96%（4 155例）是细菌性腹泻，病原体主要为非伤寒沙门菌（2 776例）。共报告其他感染性腹泻事件23起，发生场所主要为学校及托幼机构（19起），传播途径主要为人传人（17起），病原体均为诺如病毒。结论 5岁以下散居儿童是四川省其他感染性腹泻的重点防控人群，学校及托幼机构是其他感染性腹泻事件发生的主要场所。今后应进一步加强监测预警和健康宣教，提高人群轮状病毒疫苗接种率，提升群众防病意识，有效降低疾病发病率。

Abstract:

Objective To analyze the epidemiological characteristics and pathogen spectrum of other infectious diarrhea in Sichuan Province for scientific evidence for following prevention and control tasks. Methods Data on the cases and etiology of other infectious diarrhea, and public health emergencies (referred to as events for short) in Sichuan Province from 2019 to 2023 were obtained from the Chinese Disease Prevention and Control Information System, and analyzed using descriptive methods. Results A total of 273 653 cases of other infectious diarrhea were reported in Sichuan Province from 2019 to 2023, with an average annual reported incidence rate of 65.41 per 100 000 population, showing an overall upward trend. The incidence showed a bimodal distribution, with peaks in February-March (n=51 161; 18.70%) and June-August (n=83 419; 30.48%). The top 3 cities (prefectures) by cumulative reported cases were Chengdu (n=66 767), Mianyang (n=32 812) and Yibin (n=20 308). The average annual reported incidence rates for males and females were 68.08/10 000 and 62.71/100 000 population, respectively. Population aged ≤4 years were dominant in the reported cases (n=156 217; 57.09%), and the children living at home were most involved (n=139 372; 50.93%). Among the 32 057 cases with confirmed etiological diagnosis, 86.48% (n=27 722) were viral diarrhea, with rotavirus (n=21 425) being the main pathogen. 12.96% of the reported cases (n=4 155) were bacterial diarrhea, with non-typhoidal Salmonella (n=2 776) as the predominant pathogen. A total of 23 other infectious diarrhea events were reported, most of which occurred in schools and kindergartens (19 events). The main route was person-to-person transmission (17 events), and all pathogens were associated with norovirus. Conclusion Individual children under 5 years old living at home are the key population for prevention and control of other infectious diarrhea in Sichuan Province, and schools and nurseries are the major settings for outbreaks of other infectious diarrhea. In the future, it is necessary to further strengthen monitoring and early warning, health education and promotion, improve the rotavirus vaccination rate in the population, enhance the public’s awareness of disease prevention, and effectively reduce the incidence of the disease.
