A child under five in Ontario has died from measles, marking the first case in the province in over ten years.

Public Health Ontario reported the child needed hospitalization and had not received a vaccination.

Since 2000, the World Health Organization has saved almost 50 million fatalities from measles.

Prime Minister Justin Trudeau attributed recent outbreaks to “growing vaccine hesitancy” in North America and worldwide.

The WHO warned that unless immediate preventative action is taken, more than half of the world’s countries will be at high or very high risk of measles outbreaks by the end of the year.
