One man, Emmanuel Bilodeau, believes his son may be the cause of the outbreak. He told CBC News that his son, who he chose not to have vaccinated, contracted measles during a holiday to Vietnam earlier in the year, before bringing it back to Canada. Here, it spread around two schools that share a bus company.

Bilodeau says that he hadn't vaccinated any of his three children, due to concerns that vaccines cause autism (which they don't). The other two children became infected with measles shortly after his first son started showing symptoms, and was taken to the local hospital.

"We worried 10-12 years ago because there was a lot of debate around the MMR vaccine," he told CBC News. "Doctors were coming out with research connecting the MMR vaccine with autism. So we were a little concerned."

Bilodeau explained that he isn't an anti-vaxxer, but he wanted to find "a vaccine that was given in a separate shot so it wasn't such a hit on the kid."
