Protect yourself & your family: All Albertans

To reduce the risk to South Zone residents, and all Albertans, we need to ensure as many people as possible are up to date with their immunizations.

Ways to limit the spread include staying home when sick, covering your mouth when you cough and early assessment and treatment by a physician.
