Ontario confirms death of infant infected with measles

An infant in southwestern Ontario who contracted measles from their mother before birth and was born prematurely has died, Ontario’s chief medical officer of health says.

The child’s mother had not been vaccinated against the viral illness, Dr. Kieran Moore said in his statement.

While measles can be fatal, especially for young children, Moore noted the child also faced other “serious medical complications.”

“While measles may have been a contributing factor in both the premature birth and death, the infant also faced other serious medical complications unrelated to the virus,” Moore said.

Almost 70 per cent of Canadians surveyed want child vaccines to be mandatory: poll

A new poll suggests nearly 70 per cent of Canadians support mandatory childhood vaccinations, but at least one public health official says she’s uncomfortable with the idea of forcing parents to immunize their kids.

The Angus Reid Institute survey landed Thursday as Public Health Ontario said 93 new measles cases have emerged in the province over the past week, bringing the total number of infections there to 1,888 since October.

The poll found 69 per cent of respondents said proof of immunization should be required for kids to attend daycare and school. That’s an increase from the 55 per cent of respondents who said the same thing last year, before a measles outbreak emerged in multiple provinces and infected mostly unvaccinated infants, kids and teens.

BC Won’t Require Measles Vaccination for Schools

Canada is in the middle of the largest measles outbreak it has seen in generations, with 2,515 cases so far this year as of May 17, which is the most recent data reported by Health Canada as of Monday.

Despite the spread of the disease B.C. is not considering making measles immunization mandatory for attending school, as it is in Ontario and New Brunswick, the Health Ministry told The Tyee in an emailed statement.

“There is no requirement from the province for students to be vaccinated to attend school, or that students’ immunization records be provided as part of school registration,” the ministry said.

Instead its strategy is mostly a reactive one, where it will use data to respond to outbreaks and exposures. B.C. will also encourage people to get vaccinated and will open school-based immunization clinics in some areas with low vaccination rates.

Dr. Robert Strang, the chief medical officer of health, told a news conference Tuesday that the patient is an adult in Halifax who recently travelled to the United States. They went to the emergency department at the QEII hospital in Halifax on Sunday night.

‘On the precipice of disaster’: Measles may be endemic in 25 years if vaccine uptake stays low, model predicts

Without a 5% higher measles, mumps, and rubella (MMR) vaccination rate, measles may revert to endemicity in the United States within 25 years, while a 10% decline in vaccination could lead to 11.1 million cases of the highly contagious illness in that timeframe, according to predictions from a simulation model published today in JAMA.

Also today, the World Health Organization (WHO); UNICEF; and Gavi, the Vaccine Alliance warn that burgeoning outbreaks of vaccine-preventable diseases threaten to reverse years of progress.

Ontario School Safety Calls on Province for an Immediate Vaccine-PLUS Strategy to Tackle Current Measles Outbreak

Toronto, Ontario – [April 24, 2025] – In an urgent appeal to protect the health and safety of Ontario’s students, education workers, and families, Ontario School Safety (OSS) has issued an open letter asking the Ontario Provincial Government and Public Health Ontario for an immediate vaccine-PLUS strategy, which includes the essential role of healthy indoor air, to curtail the spread of measles. This critical request comes in the wake of concerning measles infection rates – as of April 17th, 2025, Public Health Ontario is reporting 925 measles cases in the province, more than five times the number of cases than the total number of cases over the last 12 years. Encouraging a vaccine-only strategy is insufficient due to barriers to access, and because measles spreads not only through direct contact with secretions or contaminated surfaces, but through the air we breathe.

Airborne Danger

Stuffy, crowded classrooms mean kids are breathing in viruses and pollution. Parents are trying to make the air safer, but hitting roadblocks.

In September 2023, Heather Pun started sending her son to school with a carbon dioxide monitor. He was spending his days in a stuffy portable classroom, and she worried that COVID was being passed lung-to-lung through the stale air.

The device, which reads the concentration of carbon dioxide (CO2) in the air, showed CO2 levels as high as 3,500 parts per million (ppm) in his classroom.

Respiratory season ends, B.C. launching spring COVID-19 vaccination campaign

Respiratory illness season is over, British Columbia’s top doctor said Friday, but the province is set to launch a spring COVID-19 immunization campaign and wants everyone to ensure they’re fully protected against measles.

Provincial health officer Dr. Bonnie Henry said B.C.’s COVID-19 hospitalizations have hit the lowest level since 2020, with about 40 people in hospital, while cases of influenza and respiratory syncytial virus, or RSV, have also been declining.

Still, Henry said there have been resurgences in spring and summer in the past, and the province is focused on protecting people at the highest risk of serious illness.

Measles ‘inevitable’ in Ottawa, expert warns as Ontario outbreak spreads

Ottawa Public Health has begun monitoring wastewater for evidence of measles in the city as the highly infectious disease continues to surge throughout Ontario.

That makes Ottawa one of the only communities in the province and across Canada using wastewater as a possible early warning signal for measles. Ottawa Public Health says the tool is promising for detecting measles, but the research is limited and “many unknowns remain”.

There have been no cases in Ottawa so far this year but Dr. Gregory Rose, who is director of infection prevention and control at Queensway Carleton Hospital, warns that it is only a matter of time.
