Measles cases in Alberta, AHS Media
EDMONTON — It’s the outbreak that refuses to end, as measles cases continue to be reported across Alberta, with health officials warning transmission remains ongoing in all regions of the province.
The update comes during National Immunization Awareness Week, as federal officials highlight the importance of vaccines in preventing the spread of diseases such as measles.
In a statement, Health Minister Marjorie Michel said vaccine-preventable diseases continue to cause outbreaks globally and gaps in routine immunization can allow infections to re-emerge in Canada. She encouraged Canadians to stay up to date on vaccinations, calling it one of the most effective ways to protect individuals and communities.
Alberta Health says the virus is affecting people of all ages, including infants, children and adults, with most cases reported among children under five and youth aged five to 17 who are not immunized.
Confirmed cases have now been recorded in every health zone, with the highest numbers in the north, south and central regions. Officials say some infections may be going undetected, particularly in communities with lower levels of immunity.
As of April 28, the province has reported 297 confirmed cases in 2026, including 139 in the south zone, 88 in the north zone and 40 in the Edmonton zone. Two cases are currently considered active.
Health officials say there are no current hospitalizations linked to the outbreak.
Due to the volume of cases, Alberta has issued standing exposure advisories for the south and north zones, as well as Parkland County, including Spruce Grove and Stony Plain. Site-specific alerts will no longer be issued in those areas.
Residents, workers and visitors are being urged to ensure their measles immunizations are up to date and to remain aware of potential exposure locations listed by the province.
Public health officials say vaccination remains the most effective protection against measles and are encouraging anyone unsure of their immunization status to check with a health provider.
