Measles data from the World Health Organization show that Canada has half the number of confirmed cases as the United States, despite having a population only about one-tenth the size of its neighbour. WHO says 47,459 measles cases have been confirmed across the Americas as of July 18, which is three times higher than the total reported cases all of last year in the region. The United States has 2,260 of those cases, while Canada has confirmed 1,107. PAHO said North and South America are seeing their highest number of confirmed cases in more than two decades. Roughly 186,000 measles cases have been reported worldwide as of July.
