摘要 目的评估河南省2021年脊髓灰质炎(脊灰)野病毒及疫苗衍生脊灰病毒输入传播的风险。方法监测河南省各地区人群免疫水平、急性弛缓性麻痹病例,对输入风险进行评分,根据综合评分结果进行风险等级划分。综合评分越高,输入传播风险越高。结果输入传播的高风险(≥20分)、中风险(8~19分)、低风险(<8分)地区分别为6、14和8个。结论河南省存在脊灰野病毒和疫苗衍生脊灰病毒输入传播的风险,对不同风险等级的地区应采取针对性措施以维持无脊灰状态。 Objective To assess the risk of wild poliovirus and vaccine-derived poliovirus importation and transmission in Henan Province in 2021.Methods Indicators for the population immunity,acute flaccid paralysis(AFP)case surveillance and the risk of importation were scored,and the risk assessment was carried out according to the results of comprehensive score.The higher comprehensive score means higher risk of importation and transmission.Results The assessment showed that 6,14,and 8 regions were identified as high risk(scores≥20),medium risk(scores 8-19),and low risk(scores<8),respectively.Conclusion Henan province is at risk of wild poliovirus and vaccine-derived poliovirus importation and transmission.Targeted measures should be taken to maintain polio-free status in areas with different risk levels.
