TORONTO — Ontario is seeing a massive surge in measles cases as an ongoing outbreak spreads in the province among unvaccinated people.
Public Health Ontario is reporting 372 total cases since an outbreak began on Oct. 28, 2024.
That’s a jump of 195 cases since the agency’s last report on Feb. 27.
The spread has resulted in 31 hospitalizations, including one child who required intensive care.
The public health agency described this as a “sharp increase,” which it attributed to ongoing exposure among people who are not vaccinated.
They say the outbreak has also expanded geographically with the contagious respiratory virus spreading to seven more public health units.
The number of cases reported in Ontario is almost four times the amount reported over the course of a decade between 2013 and 2023.
