OBJECTIVES
Infection due to the 2019 novel coronavirus disease (COVID-19) is dramatically widespread around the world. The COVID-19 pandemic could increase public concern to prevent infectious disease. The present study aimed to assess the relationship between the COVID-19 epidemic and the potential decrease in seasonal influenza cases.
METHODS
This study was performed to show trends in seasonal influenza cases from the 2014-2015 season to the 2019-2020 season in 11 countries and regions, and evaluate whether the trends in the 2019-2020 season were different before and after the COVID-19 pandemic compared to previous seasons using a quasi-experimental difference-in-difference design.
RESULTS
In East Asia, the number of seasonal influenza cases in the 2019-20 season was lower after the COVID-19 transmission compared to previous years. However, this was not the case in American countries or in European countries.
CONCLUSION
The COVID-19 epidemic might have altered health behaviors, resulting in an unexpected reduction of seasonal influenza cases.
目的
2019 年新型冠状病毒病（COVID-19）的感染在全球范围内迅速蔓延。COVID-19 大流行可能会增加公众对预防传染病的关注。本研究旨在评估 COVID-19 疫情与季节性流感病例潜在减少之间的关系。
方法
本研究旨在展示 2014-2015 赛季至 2019-2020 赛季 11 个国家和地区季节性流感病例的趋势，并使用准实验差分设计评估与前几个季节相比，COVID-19 大流行前后 2019-2020 赛季的趋势是否有所不同。
结果
在东亚，与前几年相比，COVID-19 传播后 2019-20 季节的季节性流感病例数较低。然而，在美国或欧洲国家并非如此。
结论
COVID-19 疫情可能改变了卫生行为，导致季节性流感病例意外减少。
