辽阳儿童腹泻感染轮状病毒和腺病毒情况分析

Analysis of pediatric diarrhea infected rotavirus and adenovirus in Liaoyang

目的调查2010~2013年辽阳地区儿童腹泻患儿轮状病毒和腺病毒感染特点。方法应用免疫层析法检测辽阳地区儿童腹泻标本轮状病毒和腺病毒。结果辽阳地区轮状病毒2010~2013年感染率分别是27.6%、24.4%、20.4%、17.5%,差异有统计学意义(P<0.05)。轮状病毒感染0~2岁阳性率65.6%,2~4岁阳性率24.1%,4岁以上10.3%,差异有统计学意义(P<0.05)。轮状病毒高发月份为11~12月和1~3月。腺病毒感染率为4.3%、4.0%、4.1%、3.8%,差异无统计学意义(P>0.05)。年龄统计0~2岁阳性率59.8%,2~4岁阳性率30.3%,4岁以上阳性率9.8%,差异有统计学意义(P<0.05)。腺病毒发病率无明显季节性。结论轮状病毒发病逐年下降,与人们生活环境和对该病认知程度有关,轮状病毒感染与季节有关,腺病毒散在感染。轮状病毒和腺病毒是4岁以下儿童腹泻重要原因。

ObjectiveTo investigate characteristics of pediatric diarrhea infected rotavirus and adenovirus in Liaoyang during 2010~2013.MethodsImmunochromatographic method was applied to detect pediatric diarrhea infected rotavirus and adenovirus in Liaoyang.ResultsInfection rates of rotavirus in Liaoyang during 2010~2013 were respectively 27.6%, 24.4%, 20.4%, and 17.5%, and their difference had statistical significance （P〈0.05）. Infected rotavirus had positive rate in 0~2 years old as 65.6%, in 2~4 years old as 24.1%, and in over 4 years old as 10.3%. Their difference had statistical significance （P〈0.05）. High incidence of rotavirus was during November^December and January^March. Infection rates of adenovirus were 4.3%, 4.0%, 4.1%, and 3.8%. Their difference had no statistical significance （P〉0.05）. Its positive rate in 0~2 years old was 59.8%, in 2~4 years old was 30.3%, and over 4 years old was 9.8%. Their difference had statistical significance （P〈0.05）. Adenovirus had no obvious seasonal morbidity.ConclusionGradually reduced morbidity of rotavirus infection is related with awareness of living environment and cognition of the disease. Rotavirus infection is related with seasons, and adenovirus infection is not seasonal. Both rotavirus and adenovirus are the main causes of pediatric diarrhea in children under 4 years old.
