There’s a tick population boom happening in Eastern Ontario

Eastern Ontario is at the epicentre of a tick population boom, and with it, health officials are reporting the highest levels of Lyme disease in the province.

So far this year, there have been 186 confirmed cases of Lyme disease in south-east and Eastern Ontario, stretching from about Prince Edward County to the Quebec border, including Ottawa, according to Public Health Ontario. That is more than half of all the cases in the province since the beginning of 2025.

By far, the highest concentration of the tick-spread disease in the province is within the large South East Health Unit, which includes Smiths Falls, Brockville, Kingston, Belleville and Prince Edward County, among other regions. With 132 cases, it has the highest rate of Lyme disease in Ontario.

Ottawa, with 41 cases, and the Eastern Ontario Health Unit, with 13 cases, also have higher-than-average rates of Lyme disease. Those reported cases reflect the climate-driven growth of tick populations across the area and heightened risk of Lyme disease and anaplasmosis, which are both spread by blacklegged ticks carrying bacteria.

B.C.’s premier says measles spikes across Canada a result [of] anti-vax ‘recklessness’

VANCOUVER – 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.

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.

Ottawa: Contact councillors — save our wastewater monitoring!

📣 Let municipal councillors know you want funding for wastewater monitoring to continue

Why take action? The funding for Ottawa’s wastewater monitoring program is currently set to expire in September 2025. Wastewater monitoring is an essential public health tool that provides insights into the spread of SARS-CoV-2 and other viruses in Ottawa. We need an early warning system to inform everyone about the prevalence of SARS-CoV-2 subvariants, influenza, avian flu, RSV, mpox, and other viruses.

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.

Possible treatments for long COVID at the centre of new Western study

More than 300 patients across four continents are at the centre of a Western long COVID study, which hopes to find an effective treatment for those who struggle with long COVID.

The study will look to trial two anti-inflammatory medicines as potential treatments, and hopes to bring into view people who struggle with the disease outside of North America.

“Despite the global prevalence of long COVID, patients report different symptoms and their presentation can be influenced by where they happen to live,” said Dr. Douglas Fraser, professor at Western’s Schulich School of Medicine & Dentistry. “A study with global reach, tailored to examine each patient’s most severe symptoms, has the potential to bring hope to people well beyond Canada and the U.S.”
