For this to have been a natural [occurrence] it means an infected bird from North America would have had to infect pigs in Europe, then be re-infected by those same pigs, with an unlikely cross-species mutation that allowed the bird to carry it again, then that bird would have had to fly to Asia and infected pigs there, and those Asian pigs would then have had to mutate the virus once again (while preserving the European swine and bird elements) to become humanly transmittable, and then a human would have had to catch that virus from the Asian pigs — in Mexico!
