The Avian Bird Flu is a strand of influenza that was originally found birds and ducks across North America and Asia. It has since mutated strands and become transferable from avian to avian. Then it mutated again from Avian to human. It is not transferrable human to human at the moment, but inevitably it will mutate and wipe out half the world’s population in a manner of weeks as there is no cure and all vaccines become obsolete once the strand mutates- and it mutates constantly. It is speculated to cause a death toll greater than that of the Spanish Flu. This pandemic is widely overlooked, but it isn't a matter of 'IF' it happens. It is more a matter of 'WHEN' it happens.
When the H5N1 (Avian Bird Flu) strand of influenza becomes transferable from Human to Human it will be a manor of hours before it makes it back to North America. Exporting, Importing and Planes will allow human carriers to cross boarders and oceans and affect their families with the disease. The virus doesn't have symptoms in the first couple days, so you could be a carrier and have no idea- thus infecting your family and loved ones inadvertently.
