Measles Surges: Unvaccinated Fuel Outbreak

Central Zone Sees Most Cases, Ages 5-17 Most Affected

A significant measles outbreak is spreading, with unimmunized individuals forming the vast majority of reported cases. Health officials are urging swift action and vaccination for those at risk.

High Transmission and Warning Signs

Across the region, 1,407 cases have been identified, with immunization status known for 1,310. Of those, a striking 1,156 individuals are unimmunized. In the Central Zone, including Red Deer, 108 cases have been reported, with the 5-17 age group most commonly affected.

“Anyone who attended this location at these times, who was born in or after 1970 and has fewer than two documented doses of measles-containing vaccine, may be at risk for developing measles. They should monitor for symptoms of measles and are strongly encouraged to review their immunization records.”

Measles is described as an extremely contagious airborne illness. Initial symptoms include a fever of 38.3° C or higher, accompanied by a cough, runny nose, or red eyes. A characteristic rash typically appears three to seven days after the fever begins, often starting behind the ears and spreading across the face and body.

Urgent Call for Immunization

Health authorities emphasize that measles vaccine is highly effective. The recommended schedule includes two doses, given at one year and 18 months of age. However, in response to the current circulation, additional immunizations are available. Infants aged 6 to 11 months are advised to get an early dose, though they will still need their routine vaccinations later. Individuals born before 1970 who haven’t been immunized are encouraged to consult a healthcare provider about receiving a single dose.

The Centers for Disease Control and Prevention (CDC) reports that measles is so contagious that if one person is sick with measles, 90% of the people close to them who are not immune will also get sick (CDC, 2024).

Exposure and Protective Measures

Those potentially exposed and not protected may be able to receive a vaccine within 72 hours of exposure to prevent infection. High-risk individuals, including infants under one year, those with severely weakened immune systems, or pregnant women, might be eligible for immunoglobulin within six days of exposure.

Albertans unsure about their or their child’s immunization status can contact the measles hotline at 1-844-944-3434. This number also serves as a resource for those experiencing symptoms, needing to book appointments, or seeking clinic locations.
