Anyone who attended these locations at these times, who was born in or after 1970 and has fewer than two documented doses of measles-containing vaccine, is at risk for developing measles. These individuals should self-monitor themselves of symptoms of measles and are strongly encouraged to review their immunization records.

Measles is an extremely contagious disease and is spread easily through the air.

Symptoms of Measles include:

• Fever of 38.3° C or higher; and
• Cough, runny nose and/or red eyes; and
• A rash that appears three to seven 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 rash appears red and blotchy on lighter skin colours. On darker skin colours, it can appear purple or darker than the skin around it, or it might be hard to see.

Complications of measles can include ear infections, pneumonia, inflammation of the brain, premature delivery, and rarely death. Persons who are pregnant, less than one year of age, or have weakened immune systems are at greatest risk.

If symptoms of measles do develop, individuals are advised to stay home and call Health Link at 811 before visiting any healthcare facility or provider, including a family physician clinic or pharmacy.

Measles vaccine is highly effective at preventing infection and complications. In Alberta, measles vaccine is offered, free of charge, through Alberta’s publicly funded immunization program.

The recommended schedule for measles vaccination is two doses, the first at one year of age and the second at 18 months. However, with measles currently circulating in the area, those who live in the South Zone can receive additional immunizations:

• Infants who are six months up to and including 11 months of age are recommended to receive an early dose of vaccine. However, they should still receive their routine two doses after they reach one year of age.
• If you were born before 1970 and have not been immunized, you can discuss with your healthcare provider a single dose of measles vaccine.

Following a measles exposure, vaccine given within 72 hours can prevent infection. Immune globulin (antibodies) given within six days can also prevent infection in high-risk susceptible persons who cannot safely receive vaccine or in whom it may not be effective due to age or time from exposure, as is the case for persons who are pregnant or have weakened immune systems (immunocompromised), and some infants less than 12 months of age.
