Ontario identified 78 new measles cases over the course of two weeks, public health officials said Thursday, calling it the largest outbreak the province has seen in almost 30 years.

The new cases bring Ontario’s total this year to just over 140, far surpassing the 101 total infections recorded in the province between 2013 and 2023.

Dr. Sarah Wilson, a public health physician with Public Health Ontario, said the last time there was a sizable outbreak in the province was 2008 when there was a total of 58 cases.

“This is the largest measles outbreak that we’ve experienced in the province of Ontario since measles was eliminated from Canada in 1998,” Wilson said.

Almost all of the new cases are connected to an interprovincial outbreak that began in October, which has sickened
177 people in Ontario and also saw the virus spread in New Brunswick and Manitoba.
