本文报告了应用ELISA的方法检测了1984—1987年元月临床诊断为急性胃肠炎的婴幼儿粪便标本243份,轮状病毒(RV)抗原阳性率1984年为53.8％1985年为15.58％,1986年为48.33％,1984年的标本同时进行了轮状病毒RNA基因分析,两法符合率为71.56％。1985年分别与1986年和1984年比较,P值小于0.01。证实1984年和1986年在南南地区秋冬季出现了RV流行、并形成了高峰,而且后者比前者流行高峰提前了二个月。1985年6-8月份中均有RV引起的病例,但未形成流行高峰。在年令分布上1984年和1986年3岁以内无显著区别,而1985年1—3岁患儿RV阳性率显著高于1岁以内患儿。
In this paper, 243 samples of infant stools diagnosed as acute gastroenteritis from January 1984 to January 1987 were reported. The positive rate of rotavirus (RV) antigen was 53.8% in 1984 and 15.58% in 1985, 1986, 48.33%, 1984 samples at the same time rotavirus RNA gene analysis, the coincidence rate of two methods 71.56%. 1985, respectively, compared with 1986 and 1984, P value is less than 0.01. Confirmed 1984 and 1986 in the autumn and winter in South-South region appeared RV epidemic, and the formation of the peak, and the latter than the former peak of two months in advance. In June-August 1985, all cases were caused by RV, but no epidemic peak was formed. There was no significant difference in age distribution between 1984 and 1986 within 3 years of age. In 1985, the positive rate of RV in children aged 1-3 years was significantly higher than that in children under 1 year.
