Peel Public Health is trying to determine who may have been exposed to “a lab-confirmed case” of measles in Mississauga.

The organization issued its warning Tuesday, Feb. 5, saying people in the following areas of Pearson International Airport on Jan. 27 may have been exposed:

• Lufthansa flight LH-470, from Frankfurt to Toronto (Pearson Airport, arrival at 4:08 p.m.)

• Air Canada flight AC-834 or LH-6829, from Toronto (Pearson Airport, departure at 6 p.m.) to Montreal

• Pearson International Airport (Terminal 1), from 4-8 p.m.

All individuals who may have been exposed are advised to check immunization records and “make sure you and your family members are up to date with the measles vaccination (noted as the “MMR” or “MMRV” on records),’ said Region of Peel spokesperson Lesley Hudson in a statement.

Two doses are recommended for anyone born after 1969, the statement reads.

Also, watch for signs and symptoms.

Symptoms of measles can appear up until 21 days after exposure, Peel Health said. These include a high fever, coldlike symptoms (cough/runny nose), sore eyes or sensitivity to light, small spots with a white centre on the inside of the mouth and a red rash lasting up to a week.

“Reduce the risk of spreading to others: If you think you may have measles and need to see a health care provider, you must call ahead to inform them that you may have been exposed,” Hudson said. “This will allow health care staff to take the necessary precautions to reduce the risk of infection and protect others visiting the office, clinic or hospital.”
