The flu continues to hit Canada's aboriginal communities hard. In the western province of Manitoba, total confirmed cases rose to 260, with 34 new cases added Wednesday. Almost one-third of the new cases are in the vast northern part of the province which includes more than a dozen aboriginal reserves.

The outbreak has also spread to at least six reserves in neighboring Ontario province, with one reserve reporting at least 200 people with flu symptoms.

Local leaders have blamed the rapid spread on the cramped conditions of the residents, warning "we are seeing clusters of outbreaks that have potential to move quickly through the population."

Federal and provincial government have sent additional nurses and doctors to the reserves and anyone with flu-symptoms is being treated with Tamiflu.
