Could our changing lifestyles and a changing climate spell a return of deadly diseases like malaria to Canada? A recent scientific study warns - it's possible!

Mosquito-born diseases (MBDs) like dengue fever and malaria aren't currently established in Canada, partly due to our harsh climate. But global warming combined with increasing international travel, could change all that. New research by a Canadian team from the National Microbiology Lab, the Public Health Agency of Canada (PHA) and two universities finds, given "an evolving situation" due to climate change, mosquitoes native to Canada "may become infected with new pathogens and move into new regions within Canada." But exotic species may move in, too, bringing diseases like malaria and dengue fever along with them, from afar, as well. And, "With high levels of international travel, including to locations where the diseases are present," states the report, "there will be more travel-acquired cases of MBDs." As a result, the team stresses a nee
