目的对200例腹泻患儿的大便标本进行轮状病毒检测,总结其流行病学特点。方法抽取2011年7月—2013年7月广东省急性传染病监测信息平台系统中两家腹泻监测医院上报的腹泻患儿200例,收集其大便标本检测轮状病毒。结果本组200例腹泻患儿中轮状病毒阳性者143例,阳性检出率为71.5%;其中伴蛋花样水便患儿轮状病毒阳性检出率最高,为88.2%。在这143例轮状病毒阳性患儿中,0~5个月者18例(12.6%),6个月~2岁者117例(81.8%),3~5岁者5例(3.5%),>5岁者3例(2.1%),6个月~2岁患儿所占比例最大(P<0.05);发病时间为2~4月份者15例(10.5%),5~7月份者19例(13.3%),8~10月份者51例(35.7%),11~1月份者58例(40.6%),秋冬季节发病患儿所占比例较大(P<0.05)。结论轮状病毒是导致婴幼儿腹泻的主要原因,患儿大便多为蛋花样水便,其好发年龄段为6个月~2岁,好发季节为秋冬季。
Objective To detect rotavirus in stool samples of 200 children with diarrhea and summarize their epidemiological characteristics. Methods Totally 200 children with diarrhea were collected from two diarrhea monitoring hospitals in Guangdong Acute Infectious Disease Surveillance Information Platform System from July 2011 to July 2013, and their stool samples were collected for the detection of rotavirus. Results The group of 200 cases of diarrhea in children with positive rotavirus 143 cases, the positive detection rate was 71.5%; which with egg-like water rotavirus positive detection rate was the highest (88.2%). Among 143 cases of rotavirus positive children, 18 (12.6%) were from 0 to 5 months, 117 (81.8%) from 6 months to 2 years and 5 (3.5%) were from 3 to 5 years old (2.1%) were more than 5 years old, and the largest proportion of children aged 6 months to 2 years (P <0.05). The onset time was from February to April in 15 cases (10.5%) and from May to July 19 cases (13.3%), 51 cases (35.7%) in 8-10 months, 58 cases (40.6%) from January to January, the incidence of children in autumn and winter accounted for a large proportion (P <0.05). Conclusions Rotavirus is the main cause of diarrhea in infants and young children. Most of stools in children are egg-like watery stools. The incidence of rotavirus in children is 6 months to 2 years, and the predominant season is autumn and winter.
