Hmmm. Well, it is an explanation. However, with airplanes that can put an infected person into a country on the other side of the world within 14 hours, it is not a terribly likely scenario.
Occam's Razor, google it.
Thanks for making my point. Occam's Razor, as you know, holds that researchers should avoid "stacking" information to prove a theory if a simpler explanation fits the observations. If I follow your theory, (1) the flu originated on the other side of the world; (2) from conditions unrelated to anything in Mexico; (3) and infected someone in this unspecified original location; (4) who decided to fly (5) without first infecting anyone else at the point of origin (6) to Mexico (7) where s/he infected others.
An alternative scenario is that (1) the flu strain was man made and (2) purposely released among the populace in Mexico.
“An alternative scenario is that (1) the flu strain was man made...”
Umm.... No, choice A does not follow, any more than Martians produced the virus. There is no proof for it, nor is there factual support for such a statement.
On the other hand, it’s a crackerjack theory for sure. . Though I think the this particular flu virus may be kinda’ lame, as pandemic virii go. I’ll bet/hope it’s not up to the 1918 variety. If you haven’t read it yet, there’s a couple of books (probably available at your library), “Flu : the story of the great influenza pandemic of 1918 and the search for the virus that caused it” and “America’s forgotten pandemic : the influenza of 1918”. They’re both good reads. I guess we’ll see how nasty this one is fairly soon.
