Ten British Columbians in hospital with measles as disease spreads in north
It said the infections are among 102 confirmed cases this year, with most involving people who were not fully immunized.
Deputy Provincial Health Officer Dr. Martin Lavoie said in an update on Thursday that cases are mostly centred in northern BC, with the Northern Health authority reporting 71 infections so far this year.
Lavoie said the highly contagious disease started spreading "broadly" at the end of May, and has since found "pockets of un-immunized people" in northern BC and elsewhere.
'So we don't know exactly what will occur, because we are really trying to curb the spread as much as possible, but it will run its course, unfortunately, more than likely in that group of people,' he said.
'(Once) you have a case, it tends to expose others very quickly and many are susceptible.'
Lavoie said the province had taken steps to identify those unimmunized communities, adding that his office highly recommended immunization, which he said was safe and effective.
He said BC's immunization rate of about 84 per cent was quite good but not perfect, while BC Health Minister Josie Osborne said getting immunized is the best thing BC residents can do to protect themselves and others.
The update comes after people who attended a prenatal clinic in Fort St. John, BC, were told this week that they may have been exposed to measles, with Northern Health saying up to 20 patients were exposed.
The tally of BC measles cases was up slightly from Monday, when the BC Centre for Disease Control reported 99 infections.
Six of the 10 confirmed hospitalization cases in BC are located in Northern Health, with one in each of the four other health regions.
BC released its latest case figures one day after Alberta had reported 1,230 infections since March.
While Ontario has reported the highest absolute number of cases with 2,244 confirmed infections since October, Alberta leads not only Canada, but also North America on a per-capita basis.
Lavoie said his office isn't concerned that BC could be facing a similar situation.
"So we are very close to Alberta, of course, so they could be a source (of measles) for us as people travel back and forth," he said.
"We think our coverage rates are actually not in a bad place. I said they were good, not perfect, so I would doubt we would see something that big."
Lavoie also acknowledged the high case count in Ontario in urging British Columbians to protect themselves.
Ontario reported last Thursday that an eighth infant had been born with congenital measles since the outbreak began last fall.
Infants can contract congenital measles in the womb through their mothers who are not vaccinated, resulting in severe complications, including inflammation of the brain and death.
The latest data in Ontario shows 48 pregnant people have been infected with measles, and Ontario's chief medical officer Dr. Kieran Moore announced in early June that an infant born prematurely and infected with measles died in southwestern Ontario.
Dr. Jennifer Vines, public health physician at the BC Centre for Disease Control, said during Thursday's update that BC has not yet seen such a case.
"But we are preparing for it by engaging pregnancy experts to prepare for everything we need to know on how to manage measles in pregnancy … so we can be prepared for this unfortunate possibility," Vines said.
Vines said the Ontario congenital cases reinforce the importance of everybody getting vaccinated, "but in particular, anyone who is pregnant, who knows they are susceptible to measles, getting quick follow up if they think, they have had a measles exposure, or seeking advice right away from their pregnancy provider."
Lavoie said people who are pregnant and infants, including children less than 12 months old are at risk of being infected with measles. Pregnant women and young children under the age of five also fall among the groups with a higher risk of complications and death.

MS could start up to 15 years earlier than thought, new UBC research suggests
Could doctors of the future one day spot the signs of multiple sclerosis (MS) years earlier than they do now? It's an intriguing possibility raised by new research from the University of British Columbia, which suggests the disease's earliest warning signs may materialize up to 15 years before the first classical neurological symptoms do. 'This is really important,' said senior author and UBC neurology Prof. Dr. Helen Tremlett. 'If you want to prevent MS from occurring at all, if you want to know what causes multiple sclerosis … we need to now make sure that we look much further back in time to avoid thinking that something causes MS when, in actual fact, the disease has already started.' 5:50 Cyclist Embarks on Cross-Canada Journey to Raise Awareness for Multiple Sclerosis The study, published Tuesday in the journal JAMA Network Open, came to its conclusions by analyzing the health records of more than 12,000 British Columbians. Story continues below advertisement Researchers found that patients who developed MS actually began accessing health care at a higher rate than the general population a decade and a half before their classic MS symptoms appeared. Researchers looked at doctor visits going 25 years before MS patients' symptom onset, more than double the range that prior studies have examined. Get weekly health news Receive the latest medical news and health information delivered to you every Sunday. Sign up for weekly health newsletter Sign Up By providing your email address, you have read and agree to Global News' Terms and Conditions and Privacy Policy Tremlett said the research suggests the existence of a 'prodromal phase' to MS — a period during which non-specific signs and symptoms occur before the classical onset of disease. 'Historically, MS wasn't thought to have a prodromal phase, which is a shame because other neurological conditions like Parkinson's, this concept of a prodromal phase they've been studying since the 1980s,' she said. 'They can see that before the classical onset of Parkinson's motor symptoms, maybe a decade or so before, they can pick up this prodromal phase. So I think it's super exciting that we're starting to realize this happens in multiple sclerosis as well.' 2:19 A day in the life of someone living with multiple sclerosis By studying the health records, Tremlett's team found a steady build-up in contact with the health-care system leading up to patients' MS diagnosis, with different types of doctor visits increasing at distinct points in time. Story continues below advertisement At 15 years before MS symptoms, they picked up a general increase in doctor's visits, particularly related to symptoms like fatigue, pain, dizziness and mental health conditions like depression and anxiety. At 12 years prior, they found an uptick in visits to a psychiatrist. Eight to nine years prior, visits to ophthalmologists and neurologists increased, potentially pointing to blurry vision or eye pain. Visits to the emergency room and radiology increase three to five years before MS symptom onset. And in the year before classic symptoms appeared, doctors' visits across a slew of specialties picked up, including neurology, emergency medicine and radiology. 1:38 Time spent in Canada increases MS risk for immigrants: study While that information gives researchers more threads to tug on, Tremlett stressed that these general symptoms cannot be used to diagnose MS, and that most people who experience them have nothing to worry about. Story continues below advertisement 'It's important for listeners to know that what we're looking at here is patterns of health-care use in large groups of people,' she said. 'The vast majority of people who visit a doctor for the issues I mentioned do not, and will not, develop multiple sclerosis. So I do not want anyone to feel alarmed or concerned by our findings.' However, she said the research suggests there is an opportunity in the future to recognize and potentially diagnose MS earlier, potentially through a biological marker in the blood, through family history or other combinations of clues that show someone to be in the disease's prodromal phase. Future research that achieves that goal, she said, could one day allow doctors to prevent or slow the disease's progression over the long-term. 'What I'm painting here is a picture that could be achievable in the future,' she said. 'But we're excited and we think that our findings kind of open that door to this new possibility.'

Genome BC Funds Research into the Respiratory Fallout of Wildfires
VANCOUVER, BC, Aug. 6, 2025 /CNW/ - British Columbians know the stark realities of climate change, as wildfires surge across the province. Over a million hectares burned across BC in 2024, blanketing communities in thick smoke and dramatically increasing the number of hazy, lung-choking days. As summer becomes a season of smoke, this escalating environmental challenge also has a hidden, insidious impact: a profound and lasting toll on our respiratory health. Wildfire smoke is more than just an inconvenience; it's a dangerous cocktail of particulate matter that infiltrates our lungs and bodies, exacerbating existing conditions and potentially triggering new ones. The costs are staggering, both in human lives and healthcare dollars, with Health Canada estimating up to 240 deaths and $1.8 billion in annual costs due to short-term health effects alone. In response to this challenge, Genome BC is funding three research projects that will delve into the genetic-level impacts of wildfire smoke exposure. "These projects are specifically designed to uncover what makes our vulnerable populations – from newborns to those with chronic lung conditions – more susceptible to wildfire-related respiratory issues," said Suzanne Gill, Genome BC's President and CEO. "We hope this knowledge can both inform treatment and care within our healthcare system and reduce the overall economic toll of wildfires." PROJECT 1: Wildfire Exposure and Early Childhood Health The next generation of British Columbians could be feeling the effects of wildfires before they even take their first breath. This project uses a holistic approach to study the impact of disaster exposure during pregnancy, including if it can have lasting effects on how genes are expressed in developing children. This may increase the risk of respiratory diagnoses such as asthma, bronchitis, wheezing, hives, eczema and other allergic reactions. Lead Researcher, Dr. Michael Kobor of the University of British Columbia believes the results can inform public health policies about respiratory health, especially vulnerable groups such as infants and pregnant people. "With this research, we aim to better our understanding of the impacts of prenatal wildfire disaster exposure on the next generation," he said. "Early-life environments can have a lasting impact on people throughout the course of their lives, including on their health outcomes. We hope this work will help shape healthy futures for children as global temperatures rise and wildfires become increasingly common." PROJECT 2: How Wildfire Smoke Affects People with Chronic Obstructive Pulmonary Disease (COPD) For the over 2 million Canadians living with Chronic Obstructive Pulmonary Disease (COPD), wildfire smoke presents a particularly grave threat. COPD is already the leading cause of hospitalization in Canada, costing our healthcare system an estimated $1.5 billion annually. Wildfire smoke can significantly worsen symptoms and lead to severe complications for COPD patients. Dr. Graeme Koelwyn from Simon Fraser University and and Dr. Don Sin from the University of British Columbia are studying the genomic changes in innate immune cells — our first line of defense against inhaled particles — of COPD patients. Their research aims to understand how these immune cells respond to wildfire smoke in patients at the genetic level as symptoms become worse, and to identify effective treatments. "This information is critical to develop disease management and exposure mitigation strategies for people living with COPD," Dr. Koelwyn said, "especially in this time of increasing societal and financial burden within our changing world and environment." PROJECT 3: How Wildfire Smoke and Aeroallergens Affect Lung Health Dr. Emilia Lim and Dr. Min Hyung Ryu from the University of British Columbia are focusing on airborne allergens (aeroallergens) triggered by the increase of atmospheric carbon dioxide and high temperatures that happen when there are frequent wildfires. These situations also tend to prolong allergy seasons. Our bodies generate an immune response to protect us when aeroallergens enter our lungs. "Aeroallergens are harmful to everyone, but people with lung conditions such as asthma, COPD and lung cancer survivors are at higher risk," because their immune systems are theoretically less robust, Dr. Lim explains. "It's important to know how these groups are affected differently." The researchers want to understand the links between our individual genetic differences and environmental triggers. Dr. Ryu noted, "identifying populations that are susceptible to these changes can help us find better ways to prevent and treat respiratory diseases." The Value of Proactive Research The escalating financial burden of wildfire recovery underscores the urgent need for proactive strategies. These three projects exemplify how genomics research is providing critical insights into the complex interplay between our environment and our health. "With our proximity to wildfires and access to interdisciplinary teams, Canadian researchers are uniquely equipped to tackle these questions first-hand," said Gill. "The fundamental knowledge gained will lay the groundwork for better policy decisions and more efficient treatments in the future. Any breakthroughs in respiratory health or disease prevention will translate into economic benefits for British Columbians and beyond." About Genome British Columbia: Genome BC is a not-for-profit organization that has advanced genomics research and innovation for 25 years, growing a world-class life sciences sector in BC and delivering sustainable benefits for British Columbia, Canada and beyond.

New to B.C.'s school curriculum this fall: CPR, naloxone, cardiac arrest devices
All Grade 10 students will learn first aid in gym class starting in September, and every B.C. school will be required to have medical kits to treat cardiac arrests and reverse overdoses. These significant Ministry of Education policy changes are the direct result of persistent advocacy by a group of Vancouver high schools students who watched their friend die from cardiac arrest , as well as from the parents of a University of Victoria student who didn't get the help she needed after being poisoned by toxic drugs. 'That's cool to hear. That's really great,' Tobias Zhang, who is going into Grade 12 at Point Grey Secondary, said Monday when told about the changes.

'It makes me feel like I can rest a little bit easier now. It's nice to know that this device will be in schools, and we'll all be a little bit safer in school.' Zhang and several of his classmates began lobbying last year for automated external defibrillators, or AEDs, for their school after his best friend collapsed during a Grade 9 basketball tryout in 2022. The 911 operator told the students to find an AED, but the school didn't have one. The ministry confirmed that performing CPR and using AEDs will now be part of the Grade 10 physical education curriculum at public and private schools when classes resume this fall, so 'every student will have the opportunity to gain these life-saving skills.' A ministry email said a ministerial order covering support services in schools was amended last month to make having AEDs and overdose-reversing naloxone kits mandatory. The two medical devices must be in all secondary schools before the end of 2025, and in elementary and middle schools by September 2026, the ministry says. The jury at a coroner's inquest into last year's preventable overdose death of UVic student Sidney McIntyre-Starko recommended in May that secondary schools should teach CPR and administering naloxone. Sidney's parents, Ken Starko and emergency room physician Dr. Caroline McIntyre, have created a public campaign to push for similar changes. On Monday, McIntyre applauded the policy adjustments. But she wishes information about the lethal drug supply and how to reverse overdoses would also be taught in classrooms, since toxic drugs are the leading cause of death for British Columbians ages 10 to 59. 'We are grateful that CPR and AED training will be part of the curriculum. Every child deserves to learn these basic, life-saving skills,' she said. 'I hope they include education about the toxic drug crisis, how to respond to an overdose, as well as naloxone training.' Melanie Cheng, president of the Vancouver District Parent Advisory Council, said the changes were long overdue. 'It's become an industry standard to have an AED at a recreation facility. Why not a school site,' she asked. 'It shouldn't be an option for districts. It should be mandatory. These are critical life skills that students need.' Vancouver school trustee Christopher Richardson backs the CPR, AED and naloxone requirements, but wonders why the province didn't institute them earlier. 'Let's not wait until a coroner's inquest demands this,' said Richardson, who supported the students' AED efforts. Last year, the Vancouver school board rebuffed the students' AED requests, based on advice from Vancouver Coastal Health that the devices were only necessary in schools with children with existing health conditions. The board made this call despite the fact many other districts already had AEDs in their buildings. In January, though, the board reversed course and asked the province for $250,000 to buy AEDs for all 107 schools . The new provincial directives, though, do not come with funding, so the Vancouver district will have to find the money for the AEDs, Richardson said. 'I was gravely disappointed,' he said. 'When they mandated (these changes), there was no funding. And they made that very clear.' Zhang and his friends have raised nearly $14,000 to help Vancouver school buy AEDs. Zhang said being part of the solution made him feel like he and his friends accomplished something important. While CPR and AED training are meaningful skills, what is more relevant to young people is giving them naloxone kits and training to use them, added Richardson, who is a special constable with the Vancouver police. 'Having free and easy access to nasal naloxone would improve intervention outcomes even more,' agreed Starko, Sidney's father. 'And we hope for increased government action against import of unregulated drugs and their component chemicals.' B.C.'s toxic drug crisis has claimed more than 16,000 lives since it was declared a provincial health emergency in 2016. When Sidney overdosed in a UVic residence, student witnesses immediately called 911 and campus security, who have first aid training. But she died of oxygen deprivation after not getting naloxone for 13 minutes and CPR for 15 minutes. lculbert@ For more health news and content around diseases, conditions, wellness, healthy living, drugs, treatments and more, head to – a member of the Postmedia Network.
