Anyone who may have been exposed is advised to self-monitor, review immunization records, and contact a measles hotline if symptoms develop before visiting a healthcare facility.

This incident highlights the ongoing resurgence of measles in Alberta, with nearly 2,000 cases reported since March 2025.
