PHO Rounds: An Update on Influenza for the 2022-23 Season

This session is also being offered on September 29th. With the lifting of many of the provincial public health measures implemented during earlier phases of the COVID-19 pandemic, as well as increased influenza virus activity in the southern hemisphere, it is important to plan for the possibility of co-circulation of COVID-19, influenza, and other respiratory viruses in the upcoming 2022-23 season.

This session will describe:

  • The epidemiology of the southern hemisphere’s 2022 influenza season and the possible implications for the northern hemisphere.
  • The vaccine products available as part of Ontario’s Universal Influenza Immunization Program.
  • Influenza treatment and outbreak management in the context of possible co-circulation with other respiratory viruses.
  • The respiratory virus testing algorithm for PHO laboratories.

Intended audience: Health care providers (such as physicians, nurse practitioners, pharmacists), public health staff (such as nurses, inspectors, A/MOHs, epidemiologists), and staff of long-term care homes and other congregate settings (administrators, nurses, infection prevention and control staff). General public.

By the end of this session, participants will be able to:

  • Describe historic trends in influenza and respiratory virus activity observed following reopening phases of the pandemic in Ontario, Canada, and internationally.
  • Describe influenza vaccine products available as part of Ontario’s Universal Influenza Immunization Program 2022-23.
  • Understand the use and benefits of antiviral medications for the treatment and prevention of influenza.
  • Understand influenza and other respiratory virus laboratory testing processes for the 2022-23 season.
