目的了解长兴县5岁以下儿童感染性腹泻流行特征。方法收集长兴县2013年感染性腹泻疫情数据及同期县人民医院5岁以下腹泻儿童的粪便标本,检测轮状病毒(RV)、腺病毒(Eads)及常见病原菌。结果5岁以下儿童感染性腹泻发病率为4.76%,男童发病率高于女童(P<0.05);以≤1岁为主,发病高峰季节为秋冬季;哨点医院报告以RV感染为主,阳性率22.20%,高峰月份RV阳性率高于其余月份(P<0.05),<3岁RV阳性率高于3~5岁组(P<0.05)。结论 3岁以下婴幼儿是感染性腹泻的高发人群,发病有明显的季节特征,秋冬季节为发病高峰。RV感染是长兴县5岁以下儿童感染性腹泻的主要的病毒病原,偶有混合感染。
Objective To understand the prevalence of infectious diarrhea in children under 5 years old in Changxing County. Methods The data of 2013 infectious diarrhea in Changxing County and stool samples from children under 5 years of age in People’s Hospital of Changxing County were collected to detect rotavirus (RV), adenovirus (Eads) and common pathogens. Results The incidence of infectious diarrhea in children under 5 years old was 4.76%, and the incidence in boys was higher than that in girls (P <0.05). The incidence was less than 1 year old in autumn and winter. The sentinel hospital reported RV infection , The positive rate was 22.20%. The positive rate of RV in peak month was higher than that in the other months (P <0.05). The positive rate of RV in <3 years old group was higher than that in 3 ~ 5 year old group (P <0.05). Conclusions Infants under 3 years of age are the most frequent infectious diarrhea patients with obvious seasonal characteristics and peak incidence in autumn and winter. RV infection is the main viral pathogen of infectious diarrhea in children under 5 in Changxing County, with occasional mixed infection.
