AB  - BACKGROUND: The World Health Organization (WHO) developed a structured framework 
      to enable countries to rapidly assess the severity of an influenza pandemic. This 
      framework, the Pandemic Influenza Severity Assessment (PISA), is intended to be 
      performed weekly during seasonal epidemics so that assessing influenza severity 
      during a pandemic can be done with greater ease and efficiency. OBJECTIVE: Using 
      influenza surveillance indicators within Canada's FluWatch program from seasons 
      2014-2015 to 2018-2019, national PISA thresholds were developed and assessed 
      against seasonal data for seasons 2019-2020 to June of 2022-2023. OUTCOMES: 
      Canada developed thresholds for each required indicator (transmissibility, 
      seriousness of disease and impact) for multiple WHO-recommended parameters. The 
      thresholds were assessed against four seasons, and it was determined that there 
      was a good agreement between the PISA assessments and the characterization of the 
      season by FluWatch epidemiologists. CONCLUSION: With confidence in the validity 
      of the PISA thresholds, the FluWatch program will begin to share PISA assessments 
      weekly through the FluWatch report in the 2023-2024 seasons to help characterize 
      influenza activity in Canada and inform responses to the seasonal influenza 
      epidemic.
