目的评估焦作市2013年脊髓灰质炎(脊灰)野病毒(wild poliovirus,WPV)输入传播的风险,为维持无脊灰状态提供依据。方法收集人群免疫情况、急性弛缓性麻痹(acute flaccid paralysis,AFP)病例监测等资料,按照WPV输入传播风险评估工具的分级判定标准,对每一项二级指标进行评分,运用加权法计算风险值(R)。根据R值进行风险评估,R<0.25为低风险,0.25≤R<0.75为中风险,R≥0.75为高风险。结果焦作市2013年WPV输入传播的风险值(R)为0.20。10个县中,沁阳市、博爱县和马村区R值分别0.28、0.27、0.25,其余县的R值均<0.25。结论焦作市2013年WPV输入传播风险为低风险,需要全面加强免疫规划工作管理,落实维持无脊灰各项措施,提升及时识别、发现WPV病例和疫情应对能力。
Objective To evaluate the risk of transmission and transmission of 2013 poliovirus (WPV) in Jiaozuo City in order to provide a basis for the maintenance of poliovirus status. Methods The data of population immunization and acute flaccid paralysis (AFP) were collected and scored according to the grading criteria of risk assessment tools of WPV input transmission. The weighting method was used to calculate the risk value (R). Risk assessment based on R value, R <0.25 for low risk, 0.25≤R <0.75 for medium risk, R≥ 0.75 for high risk. Results The risk value (R) of WPV input transmission in 2013 in Jiaozuo was 0.20. Of the 10 counties, the R values of Qinyang, Boyai and Macun were 0.28,0.27 and 0.25, respectively, and the R values of other counties were all <0.25. Conclusion In 2013, the risk of WPV transmission in Jiaozuo City was low risk. It is necessary to comprehensively strengthen the management of immunization programs, implement various measures to maintain poliovirus, and enhance the timely identification and detection of WPV cases and outbreak response.
