为了解深圳市检出脊髓灰质炎 (脊灰 )疫苗株病毒的急性弛缓性麻痹 (AFP)病例流行病学特征及疫苗相关麻痹型脊灰 (VAPP)病例发生情况 ,对 1 994～ 2 0 0 1年检出脊灰疫苗株病毒的AFP病例进行分析。结果显示 :病例分布在 0～ 3岁儿童 ,男性多于女性 ;发病时间、地区无明显聚集趋势 ;无脊灰疫苗免疫史的占 55 .55 % ,均为外来流动儿童 ;检出脊灰疫苗株Ⅱ型病毒占 44 .45 % ,残留麻痹率高。VAPP发生率为 0 .90 / 1 0 0万 ,服苗者VAPP发生率为0 .68/ 1 0 0万 ,首次服苗VAPP发生率为 4 .0 9/ 1 0 0万 ,服苗接触者VAPP发生率为 0 .2 3/ 1 0 0万。
This study was to make clear the epidemiological character of AFP cases with isdation of polio vaccine virus strains and the occurrence of vaccine associated paralytic poliomyelitis(VAPP) in 1994～2001 in Shenzhen.The results showed that all the AFP cases occurred in 0～3 year old children,the male was more than the female.No obvious gathering phenomenon of disease onset and geographical distribution of the cases were seen.55.55% of the cases were the nonvaccinated floating children.44.45% of the vaccine strains isolated from AFP cases were type Ⅱ polio virus and most of the cases were of residue paralysis.Estimation of the general incidence of VAPP was 0.90/1,000,000,of which the cases vaccinated was 0.68/1,000,000,the nonvaccinated contact was 0.23/1,000,000.The incidence of the newborns after their first time OPV immunization was 4.09/1,000,000.The study suggested that polio Ⅱ vaccine virus strain had once circulated in Shenzhen.It reminds us that to enhane the extra environmental surveillance for polio virus is necessary.
