江西省1996～2000年分离脊髓灰质炎疫苗相关株的AFP病例分析

An analysis of AFP cases on vacctine associated paraytic poliomyelites in Jiangxi province in 1996-2000

目的 了解江西省脊灰疫苗相关株的AFP病例状况。方法 对江西省 1996～2000年分离出脊灰苗相关的AFP病例进行流行病学和病原学分析。结果 在 5年间虽然分离的疫苗相关株有所增加,但脊灰疫苗相关病例仍在0.98/100万范围内。疫苗株以Ⅱ型为主,且分离率的高低与免疫史,服苗时间及采便时间有关,疫苗相关株间无流行学联系。结论 疫苗相关病例发病率在正常范围内。

Objective To know the status of AFP cases on vaccine assocatde paralytic poliomyelitis in JiangXi province. Motheds AFP cases on vaccine associated paralytic poliomyelitis in JianXi province in 1996~2000 were analzed by epidemiology and aetiology. Results The positive isolation rate of vaccine poliovirus had increased year by year in the five years. But the incidence of the vaccine associated paralytic poliomyelitis had been still under 0.98 per 100000 and hadn't increased. The virues isolated mainly were type II .The positive isolated rate was related to the immune experience. The time of receiving OPV and day of fe-ces collection,There weren't epidemiologic relation between. Conclusion The incidence of the vac-cine associated paralytic poliomyelitis in 1996 ~ 2000 was in the normal range.
