Canada has formally lost its measles elimination status, the country’s public health agency announced Monday, meaning all of the Americas have lost that status as well.
The decision, which was widely expected, comes after a meeting last week where an expert committee of the Pan American Health Organization determined that a large measles outbreak that began in Canada in October 2024 was still ongoing, more than 12 months after it started.
Comments closedCanada has been stripped of its measles elimination status after failing to interrupt transmission within one year of an outbreak that continues to spread in parts of the country.
The Public Health Agency of Canada said Monday it was notified by The Pan American Health Organization, a regional arm of the World Health Organization, that Canada lost its designation – an accomplishment it held for 27 years.
“While transmission has slowed recently, the outbreak has persisted for over 12 months, primarily within under-vaccinated communities,” the statement said.
Comments closedThe Pan American Health Organization has informed the Public Health Agency of Canada (PHAC) that Canada no longer has the status of a country that has eliminated measles, due to an outbreak that has been ongoing for more than one year.
This status indicates that there is no continuous transmission of the disease for 12 months or more in a given geographical area.
“Despite considerable efforts by Canada, the country has lost its status. Measles is now considered to be endemic in this country,” PAHO director Dr. Jason Barbosa told a news conference.
Comments closedTORONTO — Canada is poised to lose its international status as a measles-free country now that an outbreak that began in New Brunswick and spread to other provinces has hit the one-year mark.
The country eliminated measles in 1998 and maintained that status for more than 25 years, meaning there was no ongoing community transmission and new cases were travel-related.
But since Oct. 27, 2024, the virus has spread to more than 5,000 people in Canada, including two infants in Ontario and Alberta who were infected with measles in the womb and died after they were born.
Comments closedTORONTO – Toronto Public Health is developing a wastewater surveillance program to detect any potential spread of diseases during the FIFA World Cup.
Toronto’s new Medical Officer of Health Dr. Michelle Murti said the pilot will collect sewage samples in areas where fans congregate and test them for infections such as COVID-19, influenza and RSV.
Murti said the public health unit is looking into whether other illnesses, such as measles, could also be monitored in wastewater given the large international audience expected next summer.
Comments closedOntario’s measles outbreak, which sickened more than 2,300 people over the course of nearly a year, highlighted the consequences of declining vaccination rates and led to the death of a newborn, has been declared over.
Public Health Ontario and the province’s top doctor said Thursday the outbreak ended on Monday because it had been 46 days since any new reported cases — twice the maximum incubation period for measles.
“In Ontario, the last confirmed case developed a rash on August 21, 2025, following several months of steadily declining case numbers,” Dr. Kieran Moore, the province’s chief medical officer of health, said in an emailed statement.
Comments closedWhen Ontario rolls out its fall vaccination campaign at pharmacies, doctor’s offices and clinics across the province in the coming weeks, it will be bucking a trend.
At a time when both Alberta and Quebec have stopped funding COVID vaccines for the general public, limiting them to higher risk populations, and access to COVID vaccines is becoming limited in the United States, Ontario is moving in another direction.
The fall vaccination campaign, beginning in October, includes free access to an updated COVID-19 vaccine for the general public as well as expanded access to a vaccine to prevent RSV (respiratory syncytial virus) for older adults, and the flu vaccine.
Comments closedThe last meeting of the Centers for Disease Control and Prevention’s (CDC’s) Advisory Committee on Immunization Practices (ACIP) in June abandoned the use of its rigorous evidence-to-recommendation framework for making vaccine policy decisions, which structures decisions around key factors, including the balance of benefits and harms, the type or quality of evidence and health economic analyses, among other elements. The meeting also included new members making inaccurate statements about both vaccine safety and efficacy and included a presentation by a well-known anti-vaccine advocate that was filled with errors.
Now, the committee is set to include even more vaccine skeptics when it meets later this week, according to published reports, including multiple anti–COVID mRNA vaccine activists. (On Monday, the U.S. Department of Health and Human Services (HHS) confirmed five new ACIP members.)
Comments closedThe U.S. Centers for Disease Control has long been a global leader in disease tracking and evidence-based medical guidelines, but recent funding cuts and firings have caused many to wonder whether the institution is still a trusted source. CBC’s Nisha Patel breaks down how some of those changes could put Canadians at risk.
Comments closedST. PETERSBURG, Fla. (AP) — Florida plans to become the first state to eliminate vaccine mandates, a longtime cornerstone of public health policy for keeping schoolchildren and adults safe from infectious diseases.
State Surgeon General Dr. Joseph Ladapo, who announced the decision Wednesday, cast current requirements in schools and elsewhere as “immoral” intrusions on people’s rights that hamper parents’ ability to make health decisions for their children.
Comments closedCanada is at risk of losing its measles elimination status as an outbreak that started in New Brunswick last year continues to grow.
Measles has been considered eliminated in Canada since 1998, and the country saw an average of 91 cases annually before October 2024, when the outbreak began. The designation means that, within a certain geographical region, there has been no sustained measles transmission over 12 consecutive months.
Since then, of the 4,394 measles infections nationwide, Health Canada data shows that most individuals were exposed to the virus domestically (94 per cent) and were not vaccinated (88 per cent).
Comments closedAs Alberta’s measles outbreaks grow, researchers are now watching the province’s wastewater for the highly contagious virus and hoping to determine if the technology could eventually serve as an early detection tool.
The magnitude of Alberta’s outbreaks and the speed at which cases are climbing has sparked widespread concern. As of midday Tuesday, 1,323 cases had been confirmed since the outbreaks began in March.
Piggybacking off weekly wastewater samples, collected through the provincial COVID-19 surveillance program, the team has designed a test that can identify both the wild type measles virus (indicating actual infection) and vaccine-related shedding in the wastewater.
Comments closedAlberta has now confirmed more measles cases than the entire United States has reported this year.
The province has been battling outbreaks since March and as of noon Monday, total case counts in the province had ballooned to 1,314.
The latest update from the U.S. Centers for Disease Control and Prevention shows that country has amassed 1,288 cases this year.
Comments closedThe largest outbreak of measles in B.C. might be cresting, but there are still pockets of people without immunity spread across the province, which could lead to future outbreaks, say public health officials.
Most of the province’s confirmed 102 cases are in the northeast, where the disease has been spreading for the last couple weeks, said Dr. Martin Lavoie, deputy provincial health officer, at a press conference earlier today.
“This is not a pandemic, but measles is very serious,” Lavoie said.
He added that while there’s 102 confirmed cases there’s likely more as some people are resting and recovering at home, and have not been directly counted by health officials.
Dr. Jong Kim, chief medical officer for Northern Health, said B.C. has “likely seen the height of the wave” of the outbreak in the northeast, but that further cases are still possible, especially if the virus finds another pocket of the population where people have not received the measles, mumps and rubella vaccine.
Comments closedFREDERICTON – At least three out of the four Atlantic provinces have released data revealing their measles vaccination rates in children are below the 95 per cent threshold recommended by scientists to prevent the disease from spreading.
In Nova Scotia, the provincial government told The Canadian Press that about 23 per cent of children were not fully vaccinated for measles in 2024. Brooke Armstrong, Health Department spokeswoman, said 93.4 per cent of two-year-olds had at least one dose of vaccine and 78.6 per cent of two-year-olds had both required shots.
Prince Edward Island and New Brunswick say about 10 per cent of children are not fully vaccinated for the disease. Autumn Tremere from Prince Edward Island’s Health Department said between 91 per cent and 94 per cent of children in Grade 1 had received two doses.
New Brunswick Health Department spokeswoman Tara Chislett said the 2023-24 school immunization report showed 91.2 per cent of students with proof of immunization were up to date for the measles, mumps and rubella vaccine.
Comments closedFalling childhood vaccine coverage and a large, smoldering outbreak that was kindled in an undervaccinated pocket of West Texas have driven the United States to a troubling new milestone: There have been more measles cases in the US this year than any other since the disease was declared eliminated a quarter-century ago.
There have been at least 1,277 confirmed cases of measles reported in the US in 2025, according to data from the Johns Hopkins University Center for Outbreak Response Innovation. Just halfway through the year, the case tally has already surpassed the last record from 2019, when there were a total of 1,274 cases.
Experts say this year’s cases are likely to be severely undercounted because many are going unreported. Three people have died from measles this year – two children in Texas and one adult in New Mexico, all of whom were unvaccinated – matching the total number of US measles deaths from the previous two and a half decades.
Comments closedTORONTO – A Public Health Ontario report released Thursday suggests a continuing downward trend in new measles cases.
The health agency reported 12 new cases in the province, down from 33 additions last week and 96 the week before that.
Two more people were infected with the highly contagious disease in a northern region that includes Sault Ste. Marie and surrounding areas. That region had been showing the biggest increase in cases for a few weeks.
Meanwhile, four more people were infected in southwestern Ontario — the area that was hardest hit for months.
Comments closedVANCOUVER – British Columbia Premier David Eby says the growing spread of measles across Canada is “the sadly predictable outcome” of the “recklessness” of anti-vaccination politicians.
Eby says the disease is “no joke,” given the potentially serious impact on those infected, and it’s preventable with two vaccine shots.
He told a Vancouver news conference that the focus for provincial public health authorities now is to make sure that people who are not protected receive full vaccination.
