目的对上海市2003年维持无脊髓灰质炎(脊灰)状态工作进行评价。方法描述流行病学分析。结果上海市2003年急性弛缓性麻痹(AFP)病例监测系统共报告AFP病例30例,<15岁儿童非脊灰AFP病例报告发病率为1.81/10万,合格粪便标本采集率96.66%,口服脊灰疫苗(OPV)常规免疫接种率>99%,两轮强化免疫服苗率均>95%。近年来,加强对外来流动人口的管理是免疫预防工作的重点,针对外来人口流动频繁、流动人口卫生保健意识差等特点,基层单位每季度开展查漏补种,及时发现免疫空白点,采取相应措施。结论上海市建立了有效的免疫屏障,阻断脊灰野病毒的输入和防止疫苗衍生脊灰病毒循环的发生。
Objective To evaluate the maintenance of poliomyelitis-free status in Shanghai in 2003. Methods Describe epidemiological analysis. Results AFP cases were reported in 2003 in Shanghai. AFP cases were reported in 30 cases. The incidence of non-polio AFP cases in children <15 years old was 1.81 per 100 000 cases. The sampling rate of qualified stool samples was 96.66%. Oral ridges The routine immunization rate of gray vaccine (OPV) was> 99%, and the rate of two rounds of intensive immunization was> 95%. In recent years, strengthening the management of floating population is the key point of immunization prevention. In view of the frequent migrants and the poor awareness of health care among migrant workers, the grassroots units make leaks and replants on a quarterly basis, find out the immunization gaps and take corresponding measures . Conclusion Shanghai has established an effective immune barrier to block the input of poliovirus and prevent the occurrence of vaccine-derived poliovirus cycle.
