There’s been another sharp increase in Ontario measles cases as the province begins to release weekly reports on the infectious disease.

Public Health Ontario is reporting 470 measles cases since an outbreak began in October. That’s an increase of 120 cases since March 14.

The spread resulted in 34 hospitalizations, including two people who needed intensive care. Most of those hospitalized were unvaccinated kids, including one of the intensive care patients.

The outbreak expansion adds to the growing concern of rising measles cases in different parts of the country, including in Quebec where there are 40 cases and Alberta where there are 13, according to the latest data.
