Health units want summer camps to proactively monitor for measles
If an infection is reported at a camp in Waterloo Region, the health unit said any 'children or staff who are not fully protected with two documented doses' of the measles vaccine will be sent home. The also won't be allowed to return for at least 21 days after any potential exposure, unless they provide proof of vaccination against the virus.
The latest epidemiological summary from Public Health Ontario, updated on June 19, showed 110 measles infections were reported by Region of Waterloo Public Health between Oct. 18, 2024 and June 17, 2024. Over the last week, the total number of cases increased by 21. It is important to note, there may be a discrepancy between the region's total and the data shared by Public Health Ontario due to a lag in the reporting system and revised classification criteria.
Huron Perth Public Health
Huron Perth Public Health, meanwhile, only asked that camp providers prioritize the identification of measles symptoms, follow proper protocols and communicate with parents about the importance of measles. They also stressed 'understanding reporting requirements and procedures for managing cases and contacts.'
'Vaccination is important for camp participants as it is the best way to prevent the infection,' Dr. Miriam Klassen, the medical officer of health for Huron Perth, said in a media release. 'In addition, camp and program organizers must be prepared to respond effectively to potential measles cases to protect the community's health.'
The latest epidemiological summary from Public Health Ontario showed 249 measles infections reported by Huron Perth Public Health between Oct. 18 and June 17, an increase of 14 in the last week. Again, the data may not line up with the local health unit's case counts due to reporting delays and changing classification.
While the outbreak seems to have slowed down, public health officials said it is still important to take precautions.
What to know about measles
Measles is a highly contagious virus. The disease can spread through the air when an infected person coughs, sneezes or breathes. Even brief exposure to measles can result in illness.
Symptoms include a fever, runny nose, cough, red watery eyes, small white spots inside the mouth and a red blotchy rash. Other signs of measles include diarrhea, ear infections and pneumonia. In severe cases, measles can cause brain inflammation and death.
It usually takes between seven and 21 days for symptoms to show up.
Anyone who believes they may have been exposed to measles is asked to stay at home and avoid contact with others. If medical treatment is needed, people are urged to contact their health provider ahead of time to prevent the illness from spreading to other patients.

Doctors are seeing more non-smokers, especially women, with later-stage lung cancer
Katie Hulan, 37, is one of a growing number of non-smoking women doctors are seeing who have lung cancer. Hulan is seen in an undated handout photo. THE CANADIAN PRESS/Handout - Mohammed Asaduallah (Mandatory Credit) TORONTO — Katie Hulan's family doctor thought she might have asthma. Her cough, which had started about a month and a half earlier, was getting progressively worse. So he gave her some puffers to try, but they didn't work. 'I was just getting to the point where I couldn't speak at work,' said the 37-year-old tech marketing manager. 'At the end of the day, I would be in pain just from the shaking and coughing.' Her doctor ordered an X-ray that showed a mass on her lung. '(My doctor) said to go to emergency, thinking it was a blood clot,' Hulan remembers. After about six hours of more tests, they told her she had stage 4 lung cancer. 'That was one of the most devastating moments of my life,' she said. 'My immediate reaction was, 'I know how this story ends.' And so for me, it just felt completely like a death sentence.' She had been healthy, active and didn't smoke. 'For me to get a cancer diagnosis was a big shock. And then to have a lung cancer diagnosis was very puzzling for me,' said Hulan, who was diagnosed in Toronto in late 2020 and has since moved to Victoria where she continues treatment. She's one of a growing number of non-smokers doctors are seeing with lung cancer. Although smoking remains the leading risk factor, the Canadian Cancer Society estimates about a quarter of lung cancer cases in the country are non-smokers. In addition, more of those non-smokers are women than men and it's not clear why, said Jessica Moffatt, vice-president of programs and advocacy at the Lung Health Foundation. 'One of the theories is that potentially estrogen is doing something to perpetuate tumour growth, but it's all theories at this point,' she said. What scientists do know is that environmental factors contribute to lung cancer risk, especially radon gas. According to Health Canada, long-term exposure to radon — an invisible, radioactive gas from the breakdown of uranium in soil and rocks — is the number one cause of lung cancer among non-smokers. The agency says radon is present to some degree in every home and urges everyone to get a radon test kit to check their levels. Other risk factors include exposure to second-hand smoke, asbestos and the fine particulate matter in air pollution, Moffatt said. As wildfires rage across the country, the effects of that smoke is 'a huge concern for us' and is an area being studied to determine lung cancer risk, she said. Dr. Rosalyn Juergens, a medical oncologist at McMaster University and Hamilton Health Sciences Centre, said studies have shown that people living in areas with high air pollution rates have a higher risk of developing lung cancer. Over about 20 years in practice, she has 'absolutely' seen a rise in non-smoking lung cancer patients. 'It was uncommon for me, not never, but uncommon for me, to see a never-smoker when I first started in practice. And we are definitely seeing more and more,' said Juergens, who is also the president of Lung Cancer Canada. It's not clear whether there are more non-smokers getting lung cancer or if they just make up a greater proportion of the patients as fewer people smoke than ever before, she said. Many of her non-smoking patients are women, but people simply aren't aware of lung cancer as a women's health issue, she said. When non-smokers reach her office, their cancer is often in advanced stages. 'More women will die of lung cancer than will die of breast cancer, ovarian cancer, and cervical cancer combined,' Juergens said. 'One in five of them will be people who have never touched a cigarette a day in their lives.' Although organized lung cancer screening programs have been running in British Columbia, Ontario and Nova Scotia since 2022, they only target smokers, so non-smokers don't get the benefit of that early detection. In addition, lung cancer is often not top-of-mind for primary-care providers when non-smoking patients come in with a cough, Juergens said. 'The tricky part about lung cancer is symptoms are generally very subtle, right? Your lungs inside don't have nerve endings. So it's not like you're going to get a pain. You're never going to feel a lump,' she said. But the good news for many patients, Juergens said, is that lung cancer treatment has advanced dramatically since the 1990s, when chemotherapy was often the only option. 'We do things called next generation sequencing on the vast majority of lung cancers, and that helps us to sort what exact type of lung cancer it is and pick the right treatments,' she said. That precision medicine turned Katie Hulan's initial life expectancy of six months into an average of five to six years. A biopsy showed that her cancer had an ALK genetic mutation — one of about a dozen biomarkers that have specific medications to target the cancerous cells, and is only present in about four per cent of cases. 'When I got that news, it felt like a 180. I had life. I had hope. You know, my oncologist sat down and said, 'you won the lottery, you have years,'' she said. Almost five years after her diagnosis, Hulan continues to take a pill as her treatment, never had to undergo chemotherapy, feels 'wonderful' and is determined to live a long, full life. She now does advocacy work for the Lung Health Foundation to call for equal access to targeted cancer medication across the country and to urge people to seek medical attention if they have a cough that lasts more than two or three weeks. 'I think the word on the street is that you have to be a person who has smoked and that's not at all the case,' she said. 'Anyone with lungs can get lung cancer.'

Fast-spreading fungus deadly to endangered butternut trees attacking 3 areas of P.E.I.
Islanders are being urged to take precautions to prevent the spread of a tree fungus that has now been detected in three areas of P.E.I. Butternut canker is a fast-spreading disease that attacks butternut trees. While the trees are not believed to be native to the Island, they are widely planted across the province. "It is really a death sentence, unfortunately, for the tree once it receives butternut canker," said Clay Cutting, a technician with the P.E.I. Invasive Species Council. Once the tree is infected, there is no known way to stop the fungus's spread — eventually, the host tree dies when multiple cankers work in conjunction to girdle the tree. Cutting said the council is well aware of how devastating the fungus can be to butternut tree populations because of how the disease has impacted other provinces. According to a news release from the P.E.I. Invasive Species Council, over 80 per cent of butternut trees in Ontario have been killed by butternut canker to date, with an overall infection rate of more than 99 per cent. Symptoms and signs The fungus was first observed in trees in Stratford's Robert Cotton Park in 2024. Since then, the invasive species council conducted surveys on butternut trees in Charlottetown and Stratford and found that a majority "demonstrated signs of butternut canker infection," according to the news release. Scientists with the Canadian Forest Service confirmed the identification of the disease in July. "The most obvious sign and symptoms of butternut canker are those large, sunken cankers that appear on the trunks in the branches. They're mostly elongated, and the cankers exude a black substance," Cutting said. He said the appearance of the fungus can differ based on how long the tree has been infected, and the time of year. The colouring of the infected area can range from black to dark brown. In newer cases, the symptoms are not as obvious and can look like raised patches with small cracks in the bark that exude a black substance. How does it spread? The only confirmed way butternut canker spreads is through rainfall, Cutting said. "The rainwater will hit an infected tree, maybe spread that around the canopy, splashing fungal spores around the canopy." He's not ruling out other methods of spread like the handling of firewood, or insects and birds coming into contact with the fungus. There are no known control methods for affected populations, and butternut trees' endangered status may limit their removal based on P.E.I.'s Wildlife Conservation Act regulations. The invasive species council said Islanders can take steps to care for certain trees that have show a higher level of tolerance to the disease. This can be done by pruning out infected branches and removing cankers to help minimize the amount of the fungus in the area to potentially extend the tree's lifespan.
