Nationally, we are seeing very high levels of influenza and, again, a growing wave of COVID-19 infections. A new variant of influenza A H3N2 called subclade K is driving some of this epidemic. Subclade K has already appeared in Japan and Europe and is more severe, especially in the elderly and very young.

Last week, the Center for Infectious Disease Research and Policy reported 39,945 hospital admissions^⁠, up from 33,301 admissions the week before. While numbers have varied some week to week, they have been relatively high. There have been 19 pediatric deaths so far this season. The CDC estimates that there have been at least 15,000,000 illnesses, 180,000 hospitalizations, and 7,400 deaths from flu so far this season.

RFK Jr. appoints 2 vocal opponents of vaccine use in pregnancy to federal advisory board

Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. today appointed two obstetricians-gynecologists to the Advisory Committee on Immunization Practices (ACIP). Both appointees have a history of questioning vaccine safety in pregnancy, and one has erroneously claimed COVID-19 vaccines caused miscarriages.

Adam Urato, MD, of UMass Memorial Health, is the first listed appointee to ACIP. In October of 2024, he wrote on X, “CDC & ACOG recommend 4 vaccines in pregnancy: Flu, Tdap, RSV, & COVID. My patients often ask: ‘How do we know that all these vaccines won’t have adverse effects on my baby & me?’ The answer is: ‘We don’t.’ Women’s vax concerns should be acknowledged & their choices supported.”

‘Incomprehensibly stupid:’ How U.S. cuts in vaccine recommendations will impact Canadians

Canadian doctors are warning that a new U.S. policy which slashes the number of vaccines universally recommended to all children could have devastating, and potentially deadly effects in Canada, including increasing disease spread through American travellers visiting north of the border.

“This was just incomprehensibly stupid. I was horrified,” said family doctor and former president of the Ontario Medical Association, Dr. Sohail Gandhi in an interview with CTV News Saturday. “Children in the U.S. are going to die as a result of this move – and, worse, some children are going to have lifelong complications as a result of this move.”

As H3N2 sweeps across Canada, what to know about flu’s heart attack risk

It’s more than just a bad cold: influenza can also raise your risk of a heart attack shortly after an infection, medical experts are warning as the H3N2 strain spreads rapidly in Canada.

At the same time, flu season is coinciding with another risk factor for heart attacks – shovelling snow.

“Any time you get an infection, including a viral infection, there’s the release in your body of molecules that both trigger inflammation and sustain inflammation. And part of that is an increased tendency for your blood to clot,” said Dr. Fahad Razak, internal medicine physician at St. Michael’s Hospital and professor at the University of Toronto.

“That can have immediate effects within the weeks following an infection, resulting in things like strokes or heart attacks.”

Heather Hanwell’s 12-year-old daughter recently missed almost two weeks of school after being hit hard by a viral infection. She’s among many parents who are caring for sick kids this flu season, which so far has seen a surge of cases among school-age children.

But the experience was particularly frustrating for Dr. Hanwell, an epidemiologist who says that improving the air quality in schools would help reduce the spread of contagious respiratory illnesses.

Schools have become cesspools for cold and flu, but they don’t have to be: Ontario School Safety

The volunteer-led organization Ontario School Safety is renewing calls to the Ontario government to improve indoor air quality in schools.

The call comes as Ontario sees a rapid increase in cases of the flu, particularly impacting young children.

In April, 2021, the Government of Ontario announced it was investing over $130 million, in addition to funds from the Canadian government, to upgrade school infrastructure to protect children from COVID-19. The majority of this funding was earmarked for ventilation projects to improve indoor air quality.

At a neighbourhood Christmas party in Ottawa earlier this month, there were all the usual holiday delights: festive decor, treats and even a visit from the big man up North. It was an evening to remember for Christine Guptill, but not in the way she had imagined.

Tucked into a party room at Royale Ranch, a horse farm in the city’s south, there were nearly 40 people at the party – half children, half adults. Ms. Guptill said some children were coughing and she overheard one family say they had left their sick kid at home.

Flu hospitalizations expected to ‘increase sharply,’ officials warn, as cases surge and vaccinations lag

The Latest

Data from the Public Health Agency of Canada released today shows the number of flu outbreaks across the country is still rising, and hospitalizations due to the virus are set to surge in the coming weeks.
Health officials across the country are reporting a surge in cases of influenza this month, especially among children and youth.
There’s particular concern about low vaccination uptake this winter, with many provinces reporting only around 20 per cent of eligible residents have received the flu vaccine.
This year’s available vaccine isn’t a good match for the current predominant strain, H3N2 — but doctors are urging people to get their shots regardless.

Ten years ago, I took on a physician leadership position at my health authority that gave me a glimpse into the workings of its hospitals.

During a particular meeting that has remained burned into my memory, the department head for medicine was shaking his head in disbelief at having to state the obvious: “Why is it that every year, just like snow in winter, we know flu is coming, and yet every year flu catches us by surprise?”

The room fell silent.

An early start to Canada’s flu season is hitting children hard, sending a flood of young patients into multiple pediatric hospitals as medical teams warn that emergency visits and admissions could keep climbing in the weeks ahead.

At CHEO, eastern Ontario’s children’s hospital in Ottawa, eight times more children tested positive for influenza in November compared with the same month in 2024, while double the number of children needed to be hospitalized. Most of those children hadn’t had a seasonal flu vaccine, according to CHEO’s emergency department team.

With an absent CDC and mismatched ‘subclade K’ flu strain, experts face upcoming season with uncertainty

Published on: November 12, 2025
By Stephanie Soucheray

Earlier this month, a group of Canadian researchers published early influenza data for the 2025-26 season, issuing a warning: There has been an observed mismatch with the seasonal influenza vaccine strain and what is emerging as the dominant flu strain this season, H3N2 subclade K.

Based on early reports from Japan and the United Kingdom, the Canadian researchers wanted to publish these data to encourage enhanced surveillance in North America this season, especially given the tumultuous situation in the United States.

“This is not the time to be flying blind into the respiratory virus season,” Danuta Skowronski, MD, the epidemiology lead for influenza and emerging respiratory pathogens at the British Columbia Centre for Disease Control, told CIDRAP News. Skowronski was senior author of the paper, which was published in the Journal of the Association of Medical Microbiology and Infectious Disease Canada.
