Ontario reported 89 new measles cases last week, with the province reaching 661 cases since the fall outbreak.
By comparison, there were only 100 new cases last week, compared with 120 cases the previous week.
Public Health in Ontario said there were 52 hospitalizations — 10 more than last week — including three intensive care.
It also said measles cases still mainly involve uninoculated children in the Southwestern Ontario Public Health Department, which accounted for nearly 45% of cases in the province.
Last week, the chief medical officer of Ontario Health told Canadian media that the measles outbreak may continue into the summer, but the stability of new cases is a hopeful sign that it will not worsen.
Measles is one of the most contagious diseases in the world. The World Health Organization says the virus can remain active in the air or infected surfaces for up to two hours.
It usually starts with fever, cough, runny nose and red eyes, followed by red spotted rashes, starting on the face and spreading to the body and limbs. The virus causes pneumonia, inflammation of the brain and death.
