Canada no longer measles-free as outbreaks spread

Canada is no longer measles-free because of ongoing outbreaks, international health experts said on Monday, as childhood vaccination rates fall and the highly contagious virus spreads across North and South America.

The loss of the country’s measles elimination status comes more than a year after the highly contagious virus started spreading.

Canada has logged 5,138 measles cases this year and two deaths. Both were babies who were exposed to the measles virus in the womb and born prematurely.

Measles elimination is a symbolic designation, but it represents a hard-won battle against the infectious disease. It is earned when a country shows it stopped continuous spread of the virus within local communities, though occasional cases might still pop up from travel.

It is prevented by a vaccine administered routinely and safely to children around the world.

“It’s a deeply disheartening development. It’s a deeply worrisome development. And, frankly, it’s an embarrassing development,” said Jennifer Nuzzo, a 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.”
