采用WHO推荐的RD，HEP2两种细胞株对全省1994年送检的24例患者的45份标本进行分离培养和鉴定，结果表明，分离阳性率为33．33％（15／45），其中，非脊灰肠道病毒占60％（9／15）；其余3例（6份）经国家脊灰实验室鉴定分别为Ⅰ型疫苗相关株，Ⅱ型疫苗相关株。较之1993年，海南省脊灰发病率已大幅度下降，但疫苗相关病例及非脊灰肠道病毒引发病例均有增长趋势，需引起重视。
Using the recommended cell lines of RD and HEP2 from WHO, 45 samples from 24 patients in 1994 were isolated and identified. The results showed that the positive rate of isolation was 33.33% (15/45) , Non-polio enterovirus accounted for 60% (9/15); the remaining three cases (6) by the national polio laboratory were identified as type I vaccine-associated strains, type II vaccine-associated strains. Compared with 1993, the incidence of polio in Hainan Province has dropped drastically. However, vaccine-related cases and non-polio enterovirus-induced cases have an increasing trend, which needs attention.
