目的了解呼吸道感染婴幼儿患者肠道轮状病毒携带状况。方法采用胶体金法对338例因呼吸道感染就诊的患儿粪便标本进行轮状病毒抗原检测。结果呼吸道感染婴幼儿患者肠道轮状病毒携带率为6.8%,其中男、女患儿的携带率分别为5.4%和9.6%,差异无统计学意义(χ2=2.195,P>0.05);携带率高峰在10～12月;上呼吸道感染患儿肠道轮状病毒的携带率为19.6%,下呼吸道感染患儿的携带率为4.4%,差异有统计学意义(χ2=12.18,P<0.05)。结论呼吸道感染婴幼儿患者肠道可携带轮状病毒,感染具有明显的季节性。
Objective To understand the intestinal rotavirus carrier in infants and young children with respiratory tract infection. Methods Colloidal gold method was used to detect rotavirus antigen in 338 cases of stool samples from children with respiratory tract infection. Results The carriage rate of enteric rotavirus in infants and young children with respiratory tract infection was 6.8%. The carrying rates of boys and girls were 5.4% and 9.6% respectively, with no significant difference (χ2 = 2.195, P> 0.05) The incidence of enterovirus was 19.6% in children with upper respiratory tract infection and 4.4% in children with lower respiratory tract infection, the difference was statistically significant (χ2 = 12.18, P <0.05 ). Conclusion The intestinal tract of infants and young children with respiratory tract infection can carry rotavirus, and the infection is obviously seasonal.
