目的了解2009年-2013年本地区婴幼儿腹泻轮状病毒感染的阳性率及变化规律。方法采用乳胶凝集法对8 958例婴幼儿腹泻患儿的粪便标本进行RV抗原检测,按照性别、季节、年龄、年份和区域进行分组并对结果进行统计分析。结果男、女患儿RV阳性率分别为10.48%、9.42%。婴幼儿一年四季均可感染RV,春、夏、秋、冬四季的阳性率分别为9.06%、3.03%、5.21%、18.32%。不同年龄的患儿RV阳性率不同:<6个月的患儿为1.62%,6个月~2岁的患儿为24.42%,2岁~5岁的患儿为6.68%,>5岁的患儿为1.33%。农村患儿RV阳性率(12.58%)略高于城市患儿(7.99%)。本地区2009年-2013年每年RV阳性率控制在一定水平。结论轮状病毒感染是婴幼儿腹泻的病原体之一,应重视病原体的检测以明确诊断。仍需加强预防工作,特别是农村地区应降低婴幼儿轮状病毒的感染。
Objective To understand the positive rates and changes of rotavirus infection in infants with diarrhea in this area from 2009 to 2013. Methods RV antigen was detected in 8 958 infants and young children with diarrhea by latex agglutination. The RV antigen was detected by sex, season, age, year and region and the results were statistically analyzed. Results The positive rates of RV in male and female children were 10.48% and 9.42% respectively. Infants and young children can feel RV all year round, and the positive rates in spring, summer, autumn and winter are 9.06%, 3.03%, 5.21% and 18.32% respectively. The positive rates of RV were different in children of different ages: 1.62% in children <6 months, 24.42% in children aged 6 months to 2 years, 6.68% in children aged 2 to 5 years, Children with 1.33%. The positive rate of RV in rural children (12.58%) was slightly higher than that in urban children (7.99%). The region from 2009 to 2013 annual rate of RV positive control in a certain level. Conclusion Rotavirus infection is one of the pathogens of infantile diarrhea. Pathogen detection should be emphasized in order to confirm the diagnosis. There is still a need to step up prevention efforts, especially in rural areas, to reduce the incidence of rotavirus infection in infants and young children.
