• Pediatric hospitals, including CHEO, are seeing record-high flu cases, emergency visits, and admissions

• Ontario ICU admissions due to influenza increased by 127% in just one week

• Nationwide, over 20% of flu tests are now positive, with the highest rates among people under 19

• Medical experts warn that low vaccine uptake and partial strain mismatch may worsen outcomes

• Flu vaccination remains highly effective at preventing severe illness, hospitalization, and death

• Public health officials urge immediate vaccination, especially before holiday gatherings

Overview: A Tragic Warning as Influenza Cases Surge

Health officials in Ottawa and Eastern Ontario have confirmed the deaths of three children aged between five and nine due to influenza-related complications during the first two weeks of December. Medical officers describe the situation as unusual and alarming, highlighting concerns that the current flu season could be more aggressive than recent years.

The deaths have prompted urgent warnings from Ottawa Public Health and the Eastern Ontario Health Unit, as hospitals report rapidly increasing influenza activity—particularly among children and adolescents.

Sharp Rise in Influenza A Across Ontario

According to regional health authorities, there has been a rapid and significant increase in influenza A, particularly the H3N2 subtype, which is historically linked to more severe flu seasons.

Key indicators include:

• Influenza test positivity rates exceeding 20% nationwide

• Ontario positivity rates nearing 26%, higher than any of the last three seasons

• Children under 19 account for the majority of positive cases

• Hospital admissions and ICU cases are rising sharply

The Children’s Hospital of Eastern Ontario (CHEO) has reported exceptionally high pediatric flu cases, far exceeding seasonal norms.

Pediatric Hospitals Under Pressure

CHEO confirmed that:

• Over 300 children tested positive for influenza in the first 10 days of December

• Only 11 cases were recorded during the same period last year

• Emergency departments are seeing 220–280 visits per day

• Daily hospital admissions for flu-related illness continue to climb

Other children’s hospitals across Toronto, Waterloo, Calgary, and Montreal report similar trends, signaling a nationwide pediatric influenza wave.

ICU Admissions Jump 127% in One Week

The Ontario Hospital Association reported a 127% increase in influenza-related ICU admissions in just one week. Hospitalizations rose by 84%, while confirmed flu cases increased by 150% during the same period.

Health leaders stress that while COVID-19 and RSV levels remain relatively stable, influenza is now the dominant respiratory threat.

Why This Flu Season Is Hitting Children Hard

Experts attribute the severity to multiple overlapping factors:

1. Dominance of Influenza A (H3N2)

• Many children have little or no prior exposure to H3N2

• Lower natural immunity increases susceptibility

2. Vaccine Mismatch Concerns

• The circulating strain differs genetically from vaccine strains

• However, vaccines still significantly reduce severe illness and hospitalization

3. Declining Vaccination Rates

• Public health officials report lower flu vaccine uptake

• Only 25% of hospitalized children in past studies were vaccinated

What the Data Shows Nationwide

Federal surveillance highlights troubling trends:

• 6,799 confirmed influenza cases in early December

• 1,850 flu-related hospitalizations

• Children aged 5–11 are showing positivity rates near 64%

• Teens aged 12–19 exceeding 50% positivity

Health experts describe these levels as “sky-high.

Vaccination Remains the Strongest Defense

Despite concerns about strain mismatch, medical experts emphasize that the influenza vaccine remains highly effective at preventing severe outcomes:

• Up to 75% effectiveness in preventing hospital visits among children

• 30–40% effectiveness in adults

• Reduces risk of ICU admission, pneumonia, and death

Since immunity takes approximately two weeks to develop, officials urge families to get vaccinated before holiday gatherings.

Who Is Most at Risk?

While most people recover from the flu, severe complications are more likely among:

• Children under five

• Adults over 65

• Individuals with chronic illness or compromised immune systems

• Unvaccinated populations

Health officials warn that early surges in children often precede severe outbreaks among older adults.

Preventive Measures Beyond Vaccination

Public health authorities recommend additional precautions:

• Frequent handwashing

• Avoiding face-touching

• Staying home when sick

• Wearing masks in healthcare settings when required

• Avoiding hospital and long-term care visits while ill

These measures help reduce transmission during periods of high viral circulation.

A Season That May Worsen Before It Improves

Medical experts caution that the flu season is far from over, with peak transmission expected mid-to-late December in several regions.

“The sooner you get vaccinated, the better,” experts stress, warning that continued spread could lead to more severe outcomes among vulnerable populations, including seniors in long-term care.

Final Word: A Preventable Tragedy

The deaths of three children in Eastern Ontario serve as a sobering reminder that influenza is not a mild illness for everyone. Health leaders emphasize that vaccination, awareness, and early action remain critical tools in preventing further loss of life during what may be one of Canada’s most challenging flu seasons in years.
