Canada loses measles elimination status
Canada has lost its measles elimination status after nearly three decades due to its failure to curb a year-long outbreak, the Pan American Health Organization said on Monday, a loss that also results in the Americas region losing the status.

Measles is a highly preventable disease when countries attain a 95% vaccination coverage rate. That is the level needed for a community to achieve herd immunity and protect those who are unable to receive the vaccine, which is 97% effective after two doses.
The Public Health Agency of Canada in a statement said, “while transmission has slowed recently, the outbreak has persisted for over 12 months, primarily within under-vaccinated communities.”
A spokesperson for the province of Alberta, one of the worst-affected Canadian provinces, said cases are down more than 90% from the peak with only two active cases in Alberta for the past several weeks. It said vaccinations since March are 50% higher than a year earlier.
The United States and Mexico have had significant measles outbreaks this year, with thousands of cases and a handful of deaths. Other wealthy countries including those in Europe have also been facing declining measles vaccination rates.
Measles vaccination rates in the U.S. among kindergartners have been on the decline, government data shows.
