There are now a total of four confirmed cases of measles in B.C.
The latest confirmed case involves a student at Carver Christian High School in Burnaby.
An immunization clinic will be held at the school for staff and students as a precaution this afternoon.
Fraser Health says the student was on the same flight with two infected passengers from China. In March, it was confirmed two people who arrived in Vancouver on a Air China flight from Beijing have tested positive for measles. At the time, health authorities said people who were not immunized were at risk, and passengers whose vaccinations were not up to date should visit a doctor, public-health unit or walk-in clinic.
