A hepatitis A outbreak in Chesterfield Inlet is not over. In fact, Nunavut's Department of Health now suspects there are as many as 11 cases of the disease in the community.

It has been working to encourage all the people who might have had contact with those infected to get vaccinated as soon as possible.

Nunavut's chief medical officer of health, Dr. Mike Patterson, says there have been new cases this week.

"Once you've come in contact with hepatitis A it takes about two weeks for an infection to set in and it takes about a week for the vaccine to be effective. So, the bottom line is that the vaccine is about 95 percent effective in stopping even people who've been in close contact with hepatitis A," Patterson said.

Patterson says the strain of the disease found in Chesterfield Inlet is the same strain as what's usually found across Canada, and is likely caused from consuming contaminated food.

The government of Nunavut is working with health researchers across Canada to identify the cause.

Hepatitis A is uncommon in Canada. The treatment in outbreak situations is one dose of the vaccine to protect people for a few months to a year, Patterson said.

Some people do not get sick, but can still spread the infection to others.

Those who do have symptoms will likely get better on their own, though the length and severity of illness may vary.

"They will feel ill, very tired, stomach pain maybe some nausea and vomiting for a week or two and they may get a bit of a yellow tint to their skin," Patterson said.

In less than one per cent of cases, an infected individual can get very sick and die.

Vaccines are available at the Chesterfield Inlet health centre.
