Ontario child under 5 dies of measles: provincial health agency

A child under five years old has died of measles in Ontario, according to the province's public health agency, the first such death in more than a decade.

In a report published Thursday, Public Health Ontario said the child was not vaccinated against the highly infectious respiratory virus. It did not indicate when or where the child died, or their age. 

The report shows there were no other measles-related deaths recorded in the province between Jan. 1, 2013 and this week.

Measles has been on the rise in both Ontario and elsewhere in Canada as cases increase globally, particularly in Europe, which has seen tens of thousands of infections over the last year.

There have been 22 cases in the province so far this year, Public Health Ontario says — level of infections matching a recent high set in 2014, when there was the same number over the entire calendar year.

All of the cases were in people born after 1970, including 13 children. In 12 of those instances, the children were unimmunized, while the vaccination status of one was unknown.

Five infections, all in unvaccinated children under five years old, required hospitalization, the report says.

In an email statement, a spokesperson for Ontario's Ministry of Health offered condolences to the family of the deceased child.

"Our heart goes out to the family that has tragically lost their child. Our thoughts are with them as they navigate this challenging time," the spokesperson said. "We remind all Ontarians to stay up to date with their vaccinations to ensure themselves, and their loved ones are protected against infectious diseases."

Most of the total measles cases this year, 15 of 22, were linked to travel, Public Health Ontario says.

"In Ontario, measles has been rare, owing to the successful elimination of measles in Canada and high immunization coverage. As a result, measles cases are predominantly associated with travel," the report says.

"Due to an increase in measles activity globally, Ontario has begun to see more cases of measles."

Dr. Isaac Bogoch, an infectious diseases consultant at Toronto General Hospital, says Canadians planning to travel should ensure they are protected against the virus given the rise in infections abroad.

"The vaccine is extremely effective. It's safe, it's widely available, and it's free. Is it perfect? Of course not. Nothing's perfect, but it's really, really, really good," he told CBC Radio's Metro Morning on Friday.
