众所周知,脊髓灰质炎(以下简称脊灰)病毒是引起肢体麻痹的主要病因之一。自1954年 Salk 灭活疫苗及 Sabin 减毒活疫苗相继问世以来,在全世界进行了大规模的免疫,使脊灰的发病率大幅度地下降。尤其是发达国家,近10余年来几乎没有脊灰病例发生。尽管如此,脊灰仍然是全世界首要控制的疾病之一。然而,麻痹病例并非全都是由脊灰病毒引起,有一部份是由其他原因所致。此类问题以往虽有过报道,但未能引起足够的重视。因此,在麻痹症的发生率
It is well-known that poliomyelitis (hereinafter referred to as polio) is one of the major causes of limb paralysis. Since the 1954 Salk Inactivated Vaccine and the Sabin Live-attenuated Vaccine have been introduced one after the other, large-scale immunizations around the world have led to a dramatic decline in the incidence of polio. Especially in developed countries, almost no cases of polio have been reported in the recent 10 years. Nevertheless, polio is still one of the first controlled diseases in the world. However, not all polio cases are caused by poliovirus, and some are caused by other reasons. Although such reports have been reported in the past, they have not given sufficient attention. Therefore, the incidence of paralysis
