Public health officials in suburban Toronto are warning that passengers on a flight from Abu Dhabi to Toronto's Pearson airport may be at risk of being infected with measles.

Officials with Peel Public Health says they're sounding the warning about the Etihad Airways flight 141 on March 25 after they discovered a baby who has tested positive for the disease was aboard.

That infant has already sparked public notices about possible exposure sites at a Brampton multicultural community centre (at 150 Central Parkway), three health clinics and the Brampton Civic Hospital emergency ward.

Health officials say they're working with the Public Health Agency of Canada to identify passengers on the flight who may need a direct follow-up.

They say anyone aboard who has not had two doses of the measles vaccine or had the disease previously should watch for symptoms up until April 15.

Anyone showing symptoms are advised to call their doctor before visiting a clinic or hospital.
