【摘要】 目的 分析安庆市新型冠状病毒肺炎疫情（新冠疫情）暴发前、后2个年度，流行性感冒（流感）流行的强度和特征。方法 在“中国流感监测信息系统”中选取安庆市2019—2021年度监测数据，分析我市新冠疫情发生前、后的流感样病例就诊百分比、病原学阳性率和聚集性疫情的变化。结果 安庆市新冠疫情前、后2个年度，流感样病例就诊百分比分别为4.17%和3.78%，差异有统计学意义（χ~2=56.652,P=0.000）；病原学阳性率分别为23.43%和1.15%，差异有统计学意义（χ~2=538.694,P=0.000）。新冠疫情前的流感病毒活动呈现双峰分布，新冠疫情后全年仅检出27份流感病毒阳性样本。结论 新冠疫情中采取的严格非药物预防措施，对流感的季节性特征有重要影响。应通过疫苗接种和非药物预防等措施，做好流感防控工作。更多还原

【Abstract】 Objective Analysis the intensity and characteristics of influenza epidemic in Anqing before and after 2 years in COVID-19. Methods In the “China influenza surveillance information system”, monitoring the data of Anqing city from 2019 to 2021 were selected to analyze the changes in the percentage of influenza-like cases, the positive rate of etiology, and the aggregated epidemic situation before and after the occurrence of COVID-19. Results In 2 years before and after the COVID-19,the percentages of influenza-like cases were 4.17% and 3.786%, respectively, and the difference was statistically significant(χ~2=56.652,P=0.000).Simultaneously, the positive rates of etiology were 23.43% and 1.15%, and the difference was statistically significant(χ~2=538.69,P=0.000). The virus activity showed bimodal distribution before the COVID-19 outbreak, and only 27 positive samples were detected in the whole year after the COVID-19. Conclusions Strict non-drug preventive measures during the COVID-19 epidemic have an important influence on the seasonal characteristics of influenza. Influenza prevention and control should be done well through vaccination, non-drug prevention.更多还原
