Bird Flu: Looking The Wrong Way?

According to a study to be published in the Proceedings of the National Academy of Sciences, we've been looking the wrong way for the bird flu. Most of the U.S. surveillance efforts for the virus are directed at sampling wild migratory birds along the northern border with Canada. But scientists actually think that bird flu will arrive to the U.S. via the poultry trade from our neighbors south of the border. Why? Because countries in Central and South America lack the adequate controls to prevent the import of live birds from other countries already affected by the bird flu. So besides all the illegal immigrants and illegal drugs and psychotic pseudo-socialist dribble (Hola Hugo!) from down there, now we've got to worry about the bird flu too.
