Canada has been unable to control an ongoing outbreak of the measles virus for at least a year, and now the nation has lost its measles elimination status, the country’s Public Health Agency announced.

The U.S. is also on the brink of losing its status, after eliminating measles in 2000. As of last week, 1,681 cases had been confirmed in the U.S. this year alone, the most in more than 30 years, after an outbreak that started in West Texas.
