全球流感病毒流行规律及影响因素分析——基于世界卫生组织2009—2022年统计数据

Analysis of Global Influenza Virus Epidemiological Patterns and Influencing Factors--Based on WHO 2009—2022 statistics

目的了解2009—2022年全球人口流感病毒感染情况,分析流感病毒流行规律,为流感病毒的进一步研究和预防提供参考。方法从世界卫生组织(WHO)公布的全球流感病毒感染数据中选取2009—2022年全球感染情况,采用统计描述和卡方检验分析流感病毒流行规律。结果流感病毒流行具有冬春季的特征;甲型流感病毒感染率显著高于乙型流感病毒;北半球流感病毒感染率显著高于南半球;新冠疫情暴发对流感病毒的传播和感染具有重要影响。结论流感病毒给全球公共卫生安全带来严重威胁,因此需要对该病毒进行严密监控以降低大流行风险。

Objective To understand and analyze the influenza virus infections and epidemiological patterns in the global population from 2009—2022,and to provide reference for further research and prevention of influenza vi-rus.Methods The global infections from 2009—2022 were selected from the global influenza virus infection data published by WHO,and the influenza virus epidemic pattern was analyzed using statistical description and chi-square test.Results Influenza virus epidemics were characterized by winter and spring;influenza A viruses were significantly more prevalent than influenza B viruses;influenza viruses were significantly more prevalent in the northern hemisphere than in the southern hemisphere;and outbreaks of SARS-CoV-2 epidemics had a significant impact on the spread of influenza viruses and infection.Conclusion Influenza viruses pose a serious threat to global public health security and require close surveillance to reduce pandemic risk.
