The B.C. Centre for Disease Control is warning that travellers at Vancouver’s airport on Sunday may have been exposed to measles.
The centre says a passenger with the disease had a layover at Vancouver International Airport on June 9.
It warns passengers on an Air China flight from Beijing that arrived in Vancouver at 10:50 a.m. that day and those aboard an Air Canada flight to Regina that left at 2 p.m. may have been exposed.
The passenger went through Canada Customs and Immigration so the centre says people in the main terminal may also be vulnerable.
Measles is a highly infectious airborne disease and symptoms include fever, cough, runny nose, red eyes and a rash that starts centrally and spreads to the limbs.
Passengers, crew and travellers who may have come into contact with measles are asked to check their immunization status.
The centre says if you become ill and suspect you have measles, call your doctor and inform them so they can arrange a visit in a way that avoids infecting others in the waiting room.
Dozens of people in British Columbia have been infected with measles this year, prompting health officials to emphasize the importance of immunizations.
