Many environmentalists state that the cold climate of Alaska and other geographical factors gives no chance to these mosquito-related diseases.

It is true to lot extent that diseases like dog heartworm, myxomatosis, and encephalitis are more tropical, yet we must not forget the changing climate of the world and the high evolution rate of insects and also the viruses they carry.
