TORONTO – Four new cases of measles have been confirmed in Ontario.

They urged people who attended Our Lady of Mount Carmel elementary school on Feb. 9 and 10 or Saint Michael high school between Feb. 6 and 10 to review their immunization records.
Both schools are in Niagara Falls.
Ontario health officials are also warning people who attended an “Acquire the Fire” event in Toronto earlier this month to check their immunization records after a new measles case has been confirmed.
A statement released by the Ministry of Health and Long-Term Care said one of the people with the newly-confirmed case of measles was at the event “during the measles infection period.”

“Fortunately, most adolescents in Ontario are appropriately immunized with two doses of measles vaccine, and for most, this is highly effective at preventing measles,” the statement read.
“However, individuals who attended this event and are born after 1970 are requested to review their immunization status to ensure they are protected against measles. Blood testing to check measles immunity is not required or recommended.”

The province says those who have not been immunized should “immediately self-isolate” themselves by staying home and seek medical assistance.
Those individuals are being told not attend any public gatherings, school, work, daycare, or any post-secondary institutions until they are cleared of measles risk.
Health officials confirmed three new cases of measles in Ontario on Saturday.
