Twelve new confirmed cases of mumps in Toronto

A mumps outbreak in Toronto is getting worse.

It was two weeks ago that Toronto Public Health announced 14 confirmed cases. That number has now jumped to 26.

A student at Forest Hill Collegiate is one of the confirmed cases which has prompted a letter to be sent home to parents of students in every school board in Toronto.

The main concern is that people may think they're properly vaccinated when, in fact, they're not.

Dr. Vanita Dube with Toronto Public Health is urging people to check their records, especially if they were born between 1970 and 1992.

Two doses are needed and people born in that time frame may have only received one dose or none at all.

The majority of the 26 confirmed cases are people between 18 and 35 years old who either live in the west portion of the downtown core and/or frequent bars in the area.

"Most people will get that classic chipmunk cheek swelling in their salivary glands, get a fever, not feel well. Most people will recover at seven to 10 days. However, about 15 to 20 per cent of our cases are getting Orchitis which is inflammation of the testicles," explains Dube.

The virus is highly contagious; spread through kissing, sharing food or drink, coughing, and sneezing.
