Officials warned city residents after a lab-confirmed case and added that the public may have been exposed since the person (a minor) traveled in public areas at the airport and children's hospital while that she was infected.

Health officials said the patient is now under surveillance, but anyone in the aforementioned areas should take precautions, the agency said in a statement.

“Those born after 1970 or who have received fewer than two documented doses of a measles vaccine may be at risk of developing the disease,” they noted.

Anyone who develops symptoms of measles, including fever, cough, runny nose or red eyes, and a rash with red spots that appears three to seven days after the fever, should stay home and consult, they added.

“Measles is an extremely contagious disease and is easily transmitted through the air. There is no treatment, but it can be prevented through vaccination,” the entity said.

The measles vaccine is offered free to Albertans and is typically first given to children at age 12 months, with a second dose given between ages four and six.

Likewise, the agency stressed that if anyone thinks they may have been exposed to this case of measles, they could also receive vaccines.

“People who have received less than two doses of vaccine, are pregnant, less than 1 year old, or have a weakened immune system may be eligible to receive medications to prevent measles,” the health agency recommended .
