Nova Scotia is confirming its first case of measles.

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.

“We were well prepared for this,” Strang said. “Appropriate steps were taken very quickly when this person came in for care to minimize exposure.”

Strang said the patient had one dose of the measles vaccine when they were younger, but did not receive the second. The Health Department said in a news release that “people generally need two [doses] to be fully vaccinated” against measles.

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.

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.

A major outbreak of measles has infected more than 800 people in Ontario. It’s the first outbreak of its size since the disease was declared eliminated in 1998.

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.

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.

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.

As Canada deals with its largest measles outbreak in more than a decade, health experts say a COVID-era tool could help tame the spread.

Wastewater surveillance, which involves testing sewage samples for viral pathogens, became essential during the pandemic. The data helped overwhelmed health officials map out COVID-19’s path and better predict the trajectory of cases.

At the time, it was praised as a critical public health tool that could serve as a warning system to keep Canadians safe from future harmful infections. And as the current measles outbreak surpasses 500 cases in Canada, experts say this is the moment where leaning into regional wastewater surveillance would be most helpful.

In Gaines County, Texas, where a measles outbreak has killed one six-year-old and one adult, the measles vaccination rate among kindergarteners is just 82 per cent, according to reporting by The Atlantic.

That’s a higher measles vaccination rate than children have here in B.C.

Just under 82 per cent of two-year-olds have gotten one dose of the measles, mumps and rubella, or MMR, vaccine, and around 72 per cent of seven-year-olds have gotten both doses, according to the B.C. Childhood Immunization Coverage Dashboard’s 2023 data, which is the most recent data year available.
