Ontario Declares Measles Outbreak over After More than 2,300 Infections

The nearly year-long outbreak infected 2,375 people across 26 public health units and caused one infant death, with most cases among unvaccinated children and adolescents.

  • On Monday, Public Health Ontario declared the measles outbreak over, citing national guidance after 46 days without new cases, twice the maximum incubation period.
  • On Oct. 18 last year, the spread began after exposure to someone infected in New Brunswick and later infected 2,375 people across 26 public health units.
  • Almost three-quarters of cases were infants, children and adolescents, and more than 96 per cent were unvaccinated, highlighting gaps in vaccination status.
  • One baby in southwestern Ontario died after the mother was infected while pregnant and gave birth prematurely, the province said.
  • Officials warned measles still circulates in Canada, and elimination status could be revoked after 12 months of continuous transmission; 43 additional Ontario cases this year show ongoing risks.
