Lower flu activity this season likely due to COVID-19 restrictions, increased flu vaccination, and other factors, not to misdiagnosis of flu cases as COVID-19
Public health authorities are detecting lower than usual flu activity this season compared to previous seasons. Widespread adoption of public health measures to reduce the spread of COVID-19, such as the use of face masks, physical distancing, and travel restrictions, are likely contributing to the lower flu activity. Additional factors, including increased flu vaccinations and different transmission dynamics for the flu and COVID-19, can also influence how each disease spreads. However, flu viruses are still circulating and may peak later in the season.
