A dozen more mumps cases in Toronto

There are twelve new cases of the mumps confirmed in Toronto.

The total now sits at 26, up from 14 two weeks ago.

One of those is a student at Forest Hill Collegiate.

Health officials have sent a letter to parents of students in every school board in the city urging they check their family's immunization records

The majority of the  confirmed cases are people between 18 and 35 years old who frequent bars in the west part of the downtown core.

Dr. Vanita Dube with Toronto Public Health notes people may be at-risk and not know it.

Anyone born between 1970 and 1992 may have only received one dose of the vaccine as a child, when two are needed.
