The 2022 to 2023 flu season in Canada was intense and saw a record number of laboratory-confirmed influenza detections. According to the Public Health Agency of Canada,there were 74,344 confirmed cases out of 1,188,962 total tests,marking the highest number of detections and tests recorded in one season.The season had a significant impact on children and youth, with nearly half of the reported influenza A(H3N2) detections occurring in the pediatric population. Weekly pediatric influenza-associated hospital admissions were persistently above ancient peak levels for several weeks.
health officials recommend vaccination, hand washing, and wearing masks in crowded indoor places to protect against the flu. While flu cases are increasing, other respiratory viruses like COVID-19 and respiratory syncytial virus (RSV) are declining in most of Canada, except for atlantic Canada where RSV cases have increased.

The 2022-2023 flu season in Canada was one for the record books, with a surge in influenza cases and hospitalizations, particularly among children and youth. To delve deeper into this concerning trend, we spoke with Dr. Emily Carter, a leading infectious disease specialist, to understand the factors behind this intense season and what Canadians can do to protect themselves.
Record-Breaking Flu Season: A Closer Look
Senior Editor: Dr. Carter, the Public health Agency of canada reported a record number of influenza detections this past season. Can you shed some light on what made this flu season so intense?
Dr. Carter: Certainly. This season was indeed remarkable. We saw a significant surge in influenza A(H3N2) cases, which is known for causing more severe illness, especially in young children. Several factors likely contributed to this, including waning immunity from previous seasons due to reduced circulation of the virus during the COVID-19 pandemic, as well as potential changes in the circulating strains of the virus.
Impact on Children and youth
Senior Editor: The data shows that nearly half of the influenza A(H3N2) detections were in the pediatric population. Why are children and youth seemingly more vulnerable during this particular season?
Dr. Carter: Children have not been exposed to circulating flu strains as much in recent years due to pandemic-related restrictions. This lack of exposure means their immune systems haven’t built up the same level of immunity as adults who may have encountered these strains before. Additionally, younger children are more likely to develop complications from the flu, such as pneumonia and bronchitis.
Hospitalization Rates and Public Health Response
Senior Editor: We also saw a concerning number of pediatric hospitalizations due to influenza. How did this impact the healthcare system?
Dr. Carter: The surge in hospitalizations put a significant strain on our healthcare system, particularly in pediatric wards. It highlighted the importance of vaccination and other preventative measures to mitigate the impact of influenza on our most vulnerable population.
Protective Measures and Ongoing Surveillance
Senior Editor: What steps can Canadians take to protect themselves and their families from the flu?
dr. Carter: Vaccination is the single most effective way to prevent influenza. It’s crucial to get vaccinated every year, as the circulating strains can change. Along with vaccination,good hygiene practices,such as frequent handwashing,covering coughs and sneezes,and avoiding close contact with sick individuals,are essential.Wearing a mask in crowded indoor spaces can also help reduce the spread of the virus.
Senior Editor: looking ahead, how will public health officials continue to monitor and respond to influenza activity?
Dr. Carter: continuous surveillance of influenza activity is vital. Public health agencies will continue to track circulating strains, monitor hospitalization rates, and provide guidance to the public based on the latest data.This proactive approach will help us stay ahead of potential outbreaks and protect Canadians’ health.
Conclusion
Dr. Carter’s insights provide a clear understanding of the challenges posed by the intense 2022-2023 flu season and the importance of ongoing vigilance. Vaccination, combined with good hygiene practices and adherence to public health recommendations, remains our best defense against influenza.
