安徽省1991~1995年共报告AFP803例,其中采集粪便标本512例,占63.76%,从中分离出脊灰病毒37株,其它肠道病毒86株,共123株,阳性率为24.02%,以上脊灰病毒除1991年6株未作型内鉴别外,其余经型内鉴别,均确定为疫苗相关株。1994年和1995年的脊灰病毒带毒率调查中,共采集1533份粪便标本,分离出脊灰病毒18株,其它肠道病毒138株,1994年分离的14株脊灰病毒经型内鉴别,亦确定为疫苗相关株。1993年0~3岁儿童脊灰中和抗体测定,三个型别抗体阳性率均在96%以上,处于较高水平。自1992年以来,已连续4年未发现脊灰野病毒的存在,说明本省已基本阻断了脊灰野病毒的传播。
A total of 803 cases of AFP were reported from 1991 to 1995 in Anhui Province. Among them, 512 cases of faecal samples were collected, accounting for 63.76%, of which 37 were isolated from poliovirus and 86 were other enteroviruses with a total positive rate of 24.02 % Of the above poliovirus in addition to 6 strains in 1991 did not make intra-differential identification, the other by type identification, were identified as vaccine-related strains. Poliovirus polio rate survey in 1994 and 1995, a total of 1533 samples of stool collected, isolates of poliovirus 18, 138 other enteroviruses in 1994 isolated 14 poliovirus type identification , Also identified as vaccine-related strains. In 1993 0-3 years old children polio neutralization antibody determination, the three types of antibody positive rates were above 96%, at a high level. Since 1992, the existence of wild poliovirus has not been found for four consecutive years, indicating that the province has basically blocked the transmission of poliovirus.
