Out of nowhere, swine flu has become a major health concern. The World Health Organization has called the outbreak a “public health emergency of international concern,” and has raised its pandemic alert level in response to the recent outbreak. The U.S. government has advised against nonessential travel to Mexico, a country that has been hit hard with swine flu. Similarly, the European Union’s health commissioner has advised against travel to both the United States and Mexico, where most of the reported infections have originated.
