Overview

  • Alberta has confirmed 1,314 cases since March, overtaking the US total of 1,288 for the year, with over 100 Albertans hospitalized and no deaths reported.
  • New Brunswick health authorities have declared an outbreak in the Sussex region, reporting three confirmed and five probable cases with additional investigations underway.
  • Manitoba has recorded 130 cases, marking its highest tally since measles elimination in 1998 and driven by regional MMR coverage below the 95% threshold.
  • UK regions have reported child hospitalizations, a measles-related death in Liverpool and the first Wirral case, reflecting Europe’s 2024 peak of 148,974 cases.
  • Provincial health officials are expanding early-dose eligibility, issuing exposure advisories and launching pop-up vaccination clinics to restore herd immunity before fall transmission intensifies.
