1969年12月——1971年2月间在得文州从1例死于脑炎的儿童和几例其他病人分离出ECHO17病毒。以前这种肠道病毒认为是无关重要的病毒,但在这三年间蔓延整个英国,从152例病人分离出该病毒,其中89例有神经症状。1969年秋病例开始增加,1970年夏发生暴发。这种情况在其他肠道病毒也观察得到,表明肠道病毒在当时社会上活动的时间与其说是一个夏季倒不如说蔓延了两年。在最近夏秋季末从几例分离出的肠道病毒在社会上已不活跃,可能预告病毒将成为明年疾病流行的主要原因。
ECHO17 virus was isolated from one child who died of encephalitis in December 1969-February 1971 in Texas and several other patients in Texas. Previously, this enterovirus was considered an insignificant virus, but throughout the three years it spread throughout the United Kingdom, isolating the virus from 152 patients, of which 89 had neurological symptoms. The number of cases started to increase in the autumn of 1969, and an outbreak occurred in the summer of 1970. This situation was also observed in other enteroviruses, indicating that the time it took for the enterovirus to live in the community at that time was two years longer than it was in the summer. The recent outbreak of summer and autumn from several cases of enterovirus in the community has been inactive, may warn that the virus will become the main cause of the epidemic next year.
