1985年4月至1986年3月,从儿科门诊收集了349份急性胃肠炎患儿的粪便标本,应用轮状病毒 ELISA 和 EM 技术检测了肠道病毒。肠道病毒的总检出率为26.7%。其中轮状病毒占18.9%,小圆形病毒占2.9%,其他病毒为4.9%。同时在两例患儿的粪便中检出了新因子,这些新因子形态上类似轮状病毒,但不与轮状病毒 ELISA 起反应。轮状病毒是引起2岁以下婴幼儿急性胃肠炎的主要病原。它的流行有明显的季节性,流行高峰期出现在秋末冬初。与月平均最高温度,最低温度,降水量,相对湿度无相关性。
From April 1985 to March 1986, 349 stool samples from children with acute gastroenteritis were collected from pediatric outpatients and tested for rotavirus by rotavirus ELISA and EM. The total detection rate of enterovirus was 26.7%. Among them rotavirus accounted for 18.9%, rotavirus 2.9%, other viruses 4.9%. At the same time, new factors were detected in the faeces of two children. The new factors were morphologically similar to rotavirus but did not respond to rotavirus ELISA. Rotavirus is the leading cause of acute gastroenteritis in infants under 2 years. Its prevalence has obvious seasonal, the peak of the epidemic appeared in late autumn and early winter. No correlation with monthly average maximum temperature, minimum temperature, precipitation, relative humidity.
