Ontario declares end to measles outbreak after almost a year

Ontario has declared its measles outbreak over after a nearly year-long battle, but other parts of the country are still managing new cases of the highly-infectious disease.

Public Health Ontario, in its weekly measles update posted on Thursday, announced that the provincial outbreak concluded on Oct. 6. National guidance states an outbreak is over when no new cases have been reported for 46 consecutive days, which is double the incubation period for measles.
