This could be a bio weapon spread by the ragheads, surely you can't deny that possibility.
Pigs in general are not a carrier. A specific small and localized population of pigs—perhaps just one—served as the recombinant host.
As I said, crack a book.
Please read this and educate yourself:

Do you think it was a bio weapon in 1918? Sometimes the flu really IS the flu. It’s been mutating a long, long time. That’s what viruses do.
This could be a virus spread by aliens from Beta Centauri, you can’t deny that possibility.
I think, with the ROP religion forbidding ANY contact with pig products of ANY kind, that it would have to be a case of hiring someone else (apparently not a Nobel Prize winning scientist type) to muddle several different kinds of flu together so they could be released in the US by illegal aliens (who would probably be paid quite handsomely to cross the border, not realizing they could make themselves quite sick as well, or even die from said virus/es)—my tin foil hat came out the minute I heard that museum guy died the day after meeting HolyO—too many weird connections going on in this Mexiflu mess!
