2022年4月全球新型冠状病毒肺炎疫情风险评估

Risk assessment of global COVID-19 pandemic in April 2022

  • 摘要:
      目的  评估2022年4月新型冠状病毒肺炎(COVID-19)疫情全球流行情况及对我国的输入风险。
      方法  根据美国约翰斯·霍普金斯大学公开发布的每日COVID-19疫情数据,结合牛津大学发布的政策严格性指数,采用流行病学描述方法,通过总体概述、世界卫生组织(WHO)各区及重点国家疫情趋势综合评估和周边十四国疫情与防控政策综合分析,对全球COVID-19疫情风险进行综合、全面与及时的评估。 对于各国评估结果,用“全球重点关注国家”、“WHO各分区一般关注国家”和“周边特别关注国家”予以表示。
      结果  与2022年3月相比,全球月新增确诊病例下降了45.55%,全球月新增死亡病例下降了48.28%。 相较于3月,4月新增确诊病例除美洲区(北)新增确诊病例上升18.4%外,其他各区均下降,降幅在35.3%~65.6%之间,降幅最大的为东地中海区;各区新增死亡病例均下降,降幅在26.6%~76.8%之间,降幅最大的为美洲区(南)。
      结论  全球日新增确诊病例和死亡病例4月整体呈下降趋势,但美洲区(北)区疫情仍然在加重,新增确诊病例和死亡病例仍在增加,应予以重点关注,及时沟通并调整防控措施。

     

    Abstract:
      Objective   To assess the global epidemic of Coronavirus disease 2019(COVID-19) in April 2022 and the risk of importation.
      Methods   According to the daily COVID-19 data publicly released by Johns Hopkins University, combined with the policy stringency index published by the University of Oxford, an epidemiological description method was used to provide a comprehensive and timely assessment of the global epidemic risk through a general overview, a comprehensive assessment of the epidemic trends in WHO regions and key countries, as well as a comprehensive analysis of the epidemic and prevention and control policies in 14 neighbouring countries. The assessment results for each country are expressed as “countries of global concern”, “countries of the general concern in each WHO sub-region” and “neighbouring countries of special concern”.
      Results  Compared with March 2022, the global monthly new confirmed cases dropped by 45.55%, and the global monthly new deaths dropped by 48.28%. Compared with March, except for the 18.4% increase in newly confirmed cases in the Americas (North) region, the new confirmed cases in April all declined, with a decline ranging from 35.3% to 65.6%, with the largest decline in the Eastern Mediterranean region; The number of new deaths decreased in all regions, ranging from 26.6% to 76.8%, with the largest decline in the Americas region (South).
      Conclusion   The global daily newly confirmed cases and deaths showed an overall downward trend in April, but the epidemic situation in the Americas (North) region is still aggravating, and the number of newly confirmed cases and deaths is still increasing, which should be paid special attention to, timely communicate and adjusted measures.
