BACKGROUND
The SARS-CoV-2 outbreak prompted public health interventions and changes in public behavior that may have affected the 2019-2020 influenza season.
METHODS
Using data from a laboratory in southeastern Wisconsin, we compared the number of weekly influenza tests and their positivity rates during the 2019-2020 influenza season with the previous 4 seasons.
RESULTS
The number of influenza tests per week at the outset of the SARS-CoV-2 outbreak was higher than the average the previous 4 years, and positivity rates declined to 0% earlier than any of the previous 4 seasons.
CONCLUSION
The testing trajectory and positivity rate for influenza differed during the part of the 2019-2020 season coinciding with the SARS-CoV-2 outbreak as compared to similar periods during the previous 4 seasons.
背景
SARS-CoV-2 疫情促使公共卫生干预和公众行为发生变化，这可能会影响 2019-2020 年流感季。
方法
我们利用威斯康星州东南部一个实验室的数据，将 2019-2020 年流感季每周流感检测数量及其阳性率与前 4 个流感季进行了比较。
结果
SARS-CoV-2 疫情爆发之初的每周流感检测数量高于前 4 年的平均值，且阳性率的下降时间早于前 4 个流感季的任何一个时期。
结论
与前 4 个流感季的类似时期相比，2019-2020 年流感季的检测轨迹和阳性率在 SARS-CoV-2 疫情爆发期间有所不同。
