Surveillance data on nonpolio enterovirus (NPEV) from the Centers for Disease Control (Atlanta, Georgia) for the United States from 1970 to 1983 were analyzed for the temporal and geographic patterns of the most common types of NPEV isolated. The number of isolates varied from year to year, partly because of variation in the number of reporting laboratories and partly because of true variation in the rate of isolation. The most common types isolated also varied from year to year, yet the 15 most common types over the entire 14-year period accounted for 65%-89% of isolates for a given year. The 15 most common types of NPEV had two basic patterns of isolation, one in which a type had periodic epidemic years and the other in which it did not. In 11 of the 14 years there was one or more epidemic types, each accounting for greater than or equal to 20% of all isolates of NPEV that year. The six most common isolates in March, April, and May predicted an average of 59% of the total isolates detected in July-December of that year.
对美国疾病控制中心（佐治亚州亚特兰大）1970年至1983年非脊髓灰质炎肠道病毒（NPEV）的监测数据进行了分析，以了解所分离出的最常见NPEV类型的时间和地理分布模式。分离株的数量逐年变化，部分原因是报告实验室数量的变化，部分原因是实际分离率的变化。所分离出的最常见类型也逐年不同，但在整个14年期间，15种最常见类型在某一年的分离株中占65%-89%。15种最常见的NPEV类型有两种基本的分离模式，一种是某一类型有周期性流行年份，另一种则没有。在14年中的11年里，有一个或多个流行类型，每种类型在当年所有NPEV分离株中所占比例大于或等于20%。3月、4月和5月最常见的6种分离株平均可预测当年7月至12月检测到的分离株总数的59%。
