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 understand the status of AFP cases in Jiangxi Province related to poliovirus vaccine. Methods Epidemiological and etiological analysis of AFP cases isolated from poliovirus in Jiangxi Province from 1996 to 2000 were carried out. Results Although the number of isolated vaccine-related strains increased over the five-year period, the number of polio vaccine-related cases remained within the 0.98 / 1 million range. The type Ⅱ strain was the main vaccine strain, and the isolation rate was related to the history of immunization, the service-taking time and the time of dressing-taking. There was no epidemiological relationship between vaccine-related strains. Conclusions The incidence of vaccine-related cases is within the normal range.
