１９９０～１９９５年广西壮族自治区报告急性弛缓性麻痹（ＡＦＰ）病例１１８９例，采集粪便标本９９４例，分离出病毒２２４株，阳性率２２．５４％。其中脊髓灰质炎（脊灰）病毒１５３株，分离率１５．３９％；非脊灰肠道病毒（ＮＰＥＶ）７１株，分离率７．１４％。１５３株脊灰病毒中，Ⅰ型８８株（５７．５２％），Ⅱ型４３株（２８．１０％），Ⅲ型１４株（９．１５％），混合型８株（５．２３％）。经国家脊灰实验室鉴定：１９９９０～ｌ９９２年分离到１７株Ⅰ型野毒株，ｌ株Ⅰ＋Ⅱ型野毒株；ｌ９９３～ｌ９９５年分离３１株脊灰病毒均为疫苗株。结果表明Ⅰ型是我区主要的流行毒株。
From 1990 to 1995, 1189 acute flaccid paralysis (AFP) cases were reported in Guangxi Zhuang Autonomous Region. 994 stool specimens were collected and 224 strains were isolated, the positive rate was 22.54%. Including polio (polio) virus 153 strains, isolation rate of 15.39%; non-polio enterovirus (NPEV) 71, the isolation rate of 7.14%. Among the 153 polioviruses, 88 (57.52%) were type Ⅰ, 43 (28.10%) were type Ⅱ, 14 (9.15%) were type Ⅲ and 8 (5.23% . Identification by the National Polio Laboratory: 19990 ~ l992 left to leave 17 strains of type I wild-type strains, l strains of type I + Ⅱ wild strains; l993 ~ l995 isolation of 31 poliovirus strains are vaccine strains. The results showed that type Ⅰ is the main epidemic strain in our district.
