中文摘要: 摘 要:目的:分析 2022—2023 年启东市感染性腹泻病例的流行病学特征、病原体构成,为疾病防控政策的制定提供
理论参考。方法:收集 2022—2023 年启东市各监测哨点感染性腹泻病例监测信息,对采集的粪便标本进行病原体检测,并
分析病例的流行病学特征。结果:2022—2023 年启东市共监测感染性腹泻病例 1 090 例,其中年龄在 0~4 岁的患儿最多,占
26.33% (287/1 090)。共检出肠道致病菌 41 株 (3.76%),肠道病毒 261 株 (23.94%),其中病毒以诺如病毒和轮状病毒为
主,检出率分别为 9.45% (103/1 090)、4.77% (52/1 090);细菌以沙门氏菌为主,检出率为 2.29% (25/1 090)。结论:启东
市感染性腹泻大多发生于 5 岁以下儿童群体中,存在明显的季节性特征,以冬季、夏季为发病高峰期,为加强疾病防控需采
取宣传教育、改善生活环境和习惯、持续疫情监测等方式。
Abstract: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.
