Health authorities in British Columbia have confirmed a new case of measles in the Lower Mainland, involving a Fraser Health region resident who recently returned from Southeast Asia.

Public health officials have identified potential exposure locations, including Air Canada Flight 66 arriving in Vancouver on February 11, and the Vancouver International Airport (YVR) international arrivals area between 7:00 AM and 9:30 AM on the same date.

Measles is a highly infectious disease transmitted by airborne spread, according to Fraser Health authorities. While the risk is present, health officials note that most people in Canada are protected through prior immunization or natural infection.

Health authorities recommend that individuals born in 1970 or later who have not received two doses of the measles vaccine should get a booster dose. The vaccine is provided free of charge and is most effective when received within three days of exposure, though it can still be beneficial if administered later.

Vancouver Coastal Health and Fraser Health authorities are actively conducting contact tracing and following up directly with individuals known to have been exposed to the virus.
