The presence of the H1N1 flu virus in the far north has spiked the number of cases in northwestern Ontario.
The Northwestern Health Unit says there are now 26 confirmed cases of the flu.
Medical Officer of Health Doctor James Arthurs says the pandemic is having a big impact on remote First Nation communities.
"The leadership of first nations communities is also working with Health Canada," says Arthurs, "working with the public health agency of Canada and the Ministry of Health and Long-Term Care in Ontario to address the situation and identify any support from Ontario."
Arthurs says anti-viral medications are available in most remote communities to treat those who are effected.
But Arthurs say the Health Unit won't be revealing the communities impacted by the flu based on discussion with a number of agencies, including First Nations leaders.
