Measles Outbreak In Quebec: 10 Lanaudiere Cases Linked Outbreak At Disneyland Parks

Ten individuals in Quebec are confirmed to have been infected with measles in an event health officials are linking to a large outbreak in California.

And another case has been reported in the Toronto region, bringing to eight the number of cases discovered in the past few weeks in southern Ontario.

In a statement, the Lanaudiere health authority said the first Quebec case contracted the virus during a visit to a park in California which has been the source of other recent infections. Though they do not name it, it would appear that it is Disneyland.

A large measles outbreak in the United States has been linked to the southern California theme park, which is located in Anaheim. The U.S. Centers for Disease Control says so far the Disneyland outbreak has involved 114 cases in seven U.S. states.

Canada is not the first country outside the United States to report cases related to the Disneyland outbreak. At least one case linked to the outbreak has been diagnosed in Mexico.

The measles virus is currently causing infections in several parts of Canada. In Ontario, seven cases have been reported in Toronto and one in the Niagara region in southwestern Ontario. None of the people had recently travelled outside the country, which means they contracted the virus in Canada.

And on Tuesday officials in Manitoba reported finding a case in a child who had recently returned from India.

Ontario's Health Minister, Dr. Eric Hoskins, and Dr. Robin Williams, the province's acting chief medical officer of health, urged people to check their own and their children's vaccination records.

"It is important for people to be fully immunized against this serious disease; it's the best way to prevent measles and its spread," they said in a statement.

"We are urging Ontarians to ensure all their immunizations for measles and those of their children are up-to-date, not only to protect them from this disease, but those around them. Parents who do not get their kids immunized are putting other children at risk."

In the Lanaudiere health region, authorities said all the cases are known to have been in contact with each other and all reside locally. Lanaudiere region is centred around Joliette, a city located between Montreal and Trois-Rivieres on the north side of the St. Lawrence River.

None of the 10 was vaccinated, the press release said. The statement did not indicate if the infected individuals are children, adults or a mix of the two.

Nor does it say when or how the first case returned to Quebec, how quickly after he or she got sick after travelling or whether efforts are afoot to inform people who may have been in close proximity to the case when he or she travelled.

Measles is a highly contagious disease that causes high fever, a distinctive red rash and a runny nose. While most people who become infected will only experience an unpleasant illness, the disease has a complication rate that is significant.

About one in 10 infected children will develop an ear infection, some of which lead to deafness. And about one in 10 develop pneumonia, which is the leading cause of death in measles cases, the CDC says.

It is estimated one in 1,000 children who become infected will develop swelling of the brain — encephalitis — which can lead to permanent brain damage and-or deafness. And for every 1,000 children who become infected, the CDC estimates one or two, on average, will die from the disease.
