2013—2018年襄阳市区腹泻病监测结果分析

目的了解襄阳市腹泻病病原学特征,为腹泻病的防控提供科学依据。方法采集2013—2018年襄阳市第一人民医院就诊的1341例儿科门诊及内科门诊、住院腹泻患者的新鲜粪便并进行病原学检测,分析其病原构成、人群及时间分布特征。结果1341粪便标本中,检出病原学阳性标本443例(33.04%),其中腺病毒检出率最高为8.28%(111/1341),主要为Ad31型以及其他呼吸道感染的腺病毒,其次为诺如病毒,主要为GII.3型和轮状病毒,主要流行株为P8]G9,细菌性感染比例占1.04%(14/1341)。检出率性别差异无统计学意义(P>0.05);不同年龄组人群中,0~10岁组儿童感染比例最高为45.39%(256/564);4~6月腺病毒检出率最高,10~12月轮状病毒和诺如病毒检出率较高。结论襄阳市腹泻病由多种原因引起,以病毒性腹泻为主,主要病原体为腺病毒、诺如病毒和轮状病毒,细菌性感染比例较低,该研究对指导婴幼儿喂养和病毒性腹泻的防控提供了针对性的帮助。

The etiological characteristics of diarrhea in Xiangyang City,2013-2018

Objective To understand the etiological features of diarrhea in Xiangyang city and to provide a scientific basis for the prevention and control of diarrhea.Methods A total of 1142 stool samples were collected from diarrheal patients admitted to the First People's Hospital of Xiangyang from 2013 to 2018 anwere tested for pathogens.The pathogenic composition,population characteristics and time distribution of diarrheal patients were analyzed.Results Of the 1142 diarrheal patients,737 patients(64.54%)were tested negatively.Of the 405 patients tested positively,adenovirus was the most prevalent,with proportion of 38.27%(155 patients),followed by norovirus and rotavirus.Only 20 patients(4.94%)were tested as bacterial infection.Infectious diarrhea showed obvious seasonality,with largest infectious proportion in April-June.Patients younger than 1 year old were the most susceptible to infectious diarrhea and the proportion was 29.63%(120 patients).Conclusions The majority of infectious diarrhea was viral diarrhea,and the main pathogen was adenovirus and norovirus.Only a very small proportion of diarrhea was due to bacterial infection.The guidance for infant's feeding and the surveillance and control of virus diarrhea for infants should be strengthened.
