Prince Edward Island measles cases have triggered a public health alert after two people tested positive for the virus.
Both individuals were either unvaccinated or partially vaccinated, according to the province’s chief public health office.
Officials confirmed the cases on June 27 and released a list of 10 public exposure sites.
The list includes Charlottetown Airport and two WestJet flights on June 25.
One flight travelled from Kamloops to Calgary, followed by a connection to Charlottetown.
Other exposure sites include service stations in Stanley Bridge and Scotchfort, stores in Morell and Charlottetown, and a local chapel.
Measles spreads easily through the air and close contact, such as coughing, sneezing or breathing near others.
Because it is so contagious, even brief contact in public places can lead to infection.
Typical symptoms include high fever, cough, red eyes and a blotchy red rash that appears several days after the fever begins.
Prince Edward Island health officials are urging anyone who visited these locations to watch for symptoms.
They advise people to contact a health provider if symptoms appear, but to call ahead before visiting a clinic or emergency room.
That precaution helps protect others in health care settings.
The province is encouraging all residents to review their immunization records.
Vaccination is nearly 100 per cent effective at preventing measles after two doses.
Nationally, the number of confirmed measles cases continues to rise.
As of mid-June, Health Canada had reported 3,381 cases so far in 2025.
Ontario and Alberta account for over 93 per cent of those cases.
Ontario reported 2,186, while Alberta confirmed 961.
Infections are most common among children and youth aged five to 17, followed by adults aged 18 to 54.
Although measles was declared eliminated in Canada in 1998, current outbreaks show how quickly it can return.
In Alberta, recent outbreaks are the most severe in nearly 40 years.
The disease can cause serious illness and even death, especially among infants or people with weakened immune systems.
Ontario recently reported its first measles-related death of the year.
The case involved a premature infant who became infected in the womb from an unvaccinated mother.
That tragedy renewed calls for vaccine awareness and public action.
British Columbia Premier David Eby addressed the growing concern during a news conference in Vancouver.
He blamed the resurgence, in part, on the influence of anti-vaccination politics.
“Measles is no joke. It kills kids,” Eby said. “It’s a preventable disease, and we don’t want that to be the story of the summer for our province.”
He urged all British Columbians to ensure they are fully vaccinated.
Prince Edward Island measles cases, though still limited, reflect a national trend that health experts find alarming.
Public health officials are now working to prevent further spread, especially as summer travel increases.
Children typically receive their first dose of measles vaccine at 12 months, and a second dose between ages four and six.
Adults unsure of their vaccine status may need a booster, especially before travelling or during outbreaks.
Infections can linger in the air for up to two hours, making enclosed public spaces high-risk.
That’s why prompt public exposure notifications and high vaccination rates are essential.
The province’s current alert is part of a broader national effort to manage rising infections.
Federal health agencies are coordinating with provinces to ensure rapid response, vaccine availability and public education.
The Island’s public health office says more updates will follow if additional exposure risks are identified.
Officials continue to monitor contacts of the confirmed cases and are conducting risk assessments.
Until then, health leaders are urging Islanders to stay informed, get vaccinated, and take symptoms seriously.
Vaccines not only protect individuals, but also the broader community by limiting the spread.
As summer events and travel season ramp up, Prince Edward Island is aiming to keep the focus on prevention and preparedness.
Because when it comes to measles, experts agree—prevention is always better than cure.
