Global health experts announced on Monday that the country is no longer considered measles-free due to continuing virus spread. This development coincides with childhood vaccination rates fall and the easily transmissible virus continues to spread across North and South America.

Outbreak Statistics and Tragic Outcomes

Canada has recorded 5,138 infections in the current year and two fatalities. The two individuals were infants who were exposed to the infection before birth and born prematurely.

Eradication of measles is a symbolic designation, but it represents a hard-won battle against the contagious illness. A country achieves this status when it demonstrates it has stopped continuous spread of the virus within its population, though occasional cases might still occur from travel abroad.

Recognizing The Illness

Measles typically begins with a high fever followed by a characteristic skin eruption that first appears on the head and neck area. Although many patients improve, it is one of the leading causes of childhood mortality, according to global health authorities. Severe outcomes, including blindness and swelling of the brain, are more common in young children and older adults.

“It’s a deeply disheartening development. It’s extremely concerning. And, frankly, it’s an embarrassing development,” stated an infectious disease expert, from Brown University infectious disease expert. “No country with the amount of resources of Canada – or other countries in North America even – should lose their measles elimination status.”

Historical Context and Vaccination Achievements

The country eradicated measles in 1998, with the US two years later. After extremely effective vaccination campaigns, the Americas became the first region in the world to be free of measles in recent years. Health officials calculate the immunization prevented over six million deaths in the region between the past two decades.

Current Challenges

But vaccination rates have since slipped under the 95% coverage rate needed to prevent epidemics. Large outbreaks in Venezuela and Brazil in 2018 and 2019 caused the area to lose its measles-free designation. It was regained in this year, but ends again with Canada’s loss.

Experts from the Pan American Health Organization, a public health organization, reached this conclusion after analyzing data on Canada’s outbreaks that showed the virus has spread continuously for a year.

“As a region, we have eliminated measles twice,” stated Dr. Barbosa, director of the Pan American Health Organization. “We can accomplish this once again.”

Response Measures

In a statement, Canadian health officials indicated they were collaborating with public and local organizations to enhance immunization rates, exchange information and provide evidence-based guidance.

• Boosting immunization coverage
• Improving information exchange
• Offering evidence-based advice
• Public involvement
• Official cooperation
