A public health alert posted on the Government of Alberta website on March 18, 2026, warns of potential measles exposure at multiple locations across the province, including Calgary, Red Deer, Edmonton and Grande Prairie.

The alert identifies Calgary International Airport, baggage claim carousel No. 4, as a potential exposure site on March 10 between 16:45 and 20:50 (times as listed in the public alert).

It also identifies potential exposure on a Cold Shot Bus Company route travelling from Calgary to Red Deer to Edmonton, departing March 10 at 18:20 and arriving at 22:30, and continuing from Edmonton to Grande Prairie, departing at 23:50 and arriving March 11 at 04:30. The exposure window for that trip is listed as March 10 at 18:20 to March 11 at 04:30 (times as listed in the public alert).

Additional exposure locations include the Cold Shot Bus Company terminal in Calgary at 1313 44 Ave. N.E. between 18:00 and 20:30, the Red Deer terminal at 6607 67 St. between 22:05 and 00:05, the Edmonton terminal at 11550 154 St. N.W. between 22:30 and March 11 at 01:30, and the Grande Prairie terminal at 9501 113 St. between 04:30 and 06:30 (times as listed in the public alert).

The alert states: “Anyone who attended this location at any of these times, who was born in or after 1970 and has fewer than two documented doses of measles-containing vaccine or has never had measles disease, may be at risk for developing measles and may be asked to take additional precautions if presenting to a healthcare facility.”

It also states those individuals “should monitor for symptoms of measles and are strongly encouraged to review their immunization records.”

The alert states: “Measles is an extremely contagious disease and the virus spreads easily through the air.”

Symptoms listed in the alert include “Fever of 38.3° C or higher,” along with “Cough, runny nose and/or red eyes,” and “A rash that appears 3 to 7 days after fever starts, usually beginning behind the ears and on the face and spreading down to the body and then to the arms and legs.”

The alert states: “If symptoms of measles do develop, individuals are advised to stay home and call the measles hotline at 1-844-944-3434 before visiting any healthcare facility or provider, including a family physician clinic or pharmacy.”

The alert states: “Measles vaccine is highly effective at preventing infection and complications,” adding that in Alberta, the vaccine is offered free of charge through the publicly funded immunization program.

The recommended schedule is “two doses, the first at one year of age and the second at 18 months.”

The alert states: “If you think you have been exposed, and you are not protected against measles you may be able to receive immunization to reduce the risk of infection,” adding that “A dose of vaccine needs to be given within 72 hours of exposure to prevent measles.”

For higher-risk individuals, the alert states: “Babies under one year of age, people with severely weakened immune systems, and those who are pregnant may be able to receive immunoglobulin within six days of exposure to prevent disease.”

Albertans uncertain of their immunization status are advised to call the measles hotline at 1-844-944-3434. Individuals aged 14 and older can check their records using My Health Record, and residents can also text “Measles” to 88111 for information.
