However, Canada isn’t the only country facing an uphill battle against measles—the most infectious virus known to humankind. Outbreaks and sustained spread are also active in the US and Mexico. To date, the US has documented at least 1,618 measles cases since the start of the year, while Mexico has tallied at least 5,185. Bolivia, Brazil, Paraguay, and Belize also have ongoing outbreaks, PAHO reported.
It's crazy that people are willing to let these diseases back into our societies.
Canada fought measles and measles won; virus now endemic after 1998 elimination
Canada's loss also represents a loss of regional elimination for the Americas.
