ABSTRACT:

Background

There has been a global decrease in seasonal influenza activity since the onset of the COVID-19 pandemic.

Objective

We aimed to describe influenza activity during the 2021/2022 season and compare it to the trends from 2012 to 2023. We also explored the influence of social and public health prevention measures during the COVID-19 pandemic on influenza activity.

A general additive model was used to assess the stringency index and the influenza positivity rate correlation, and the deviance explained was calculat
