本文用 ELISA 法检测了123例婴幼儿腹泻粪便标本,轮状病毒的阳性率为73.2%,2岁以下婴儿占91.3%,男女性别比为1.6:1。临床表现中:有呼吸道症状者占46.7%、发烧占58.3%、呕吐占80%、腹痛占16.7%,全部病例均有腹泻,其中10次以上/天者占50%,大便性质以黄色或黄绿色水样使者占43.3%,旦花样便占35.6%。影响因素中:人工喂养和混合喂养方式高于母乳喂养(P<0.05)、散居婴幼儿高于托幼婴幼儿(P<0.01),有接触腹泻病人史者占18.7%,有吃过不洁食物史者占40%,有家畜家禽接触史者占41.3%。结果表明 ELISA 用于检测轮状病毒敏感性高,特异性好,提出了诊断轮状病毒婴幼儿腹泻的参考依据,同时说明婴幼儿被暴露的机会是广泛的。
In this paper, 123 cases of infant diarrhea stool specimens were detected by ELISA, the positive rate of rotavirus was 73.2%, 91.3% of infants under 2 years old, male to female ratio was 1.6: 1. Clinical manifestations: respiratory symptoms accounted for 46.7%, fever accounted for 58.3%, vomiting accounted for 80%, abdominal pain accounted for 16.7%, all cases have diarrhea, of which more than 10 times / day accounted for 50% of the stool to yellow or yellow 43.3% of green water messengers, denim accounted for 35.6%. Among the influencing factors, artificial feeding and mixed feeding were higher than those of breast-feeding (P <0.05), diasporas were higher than those of nurseries and infants (P <0.01), 18.7% Food history accounted for 40% of livestock poultry history of contact accounted for 41.3%. The results showed that ELISA was used to detect rotavirus with high sensitivity and good specificity, and provided a reference basis for diagnosis of rotavirus infantile diarrhea. At the same time, the chance of infants and young children being exposed was extensive.
