The swine flu outbreak has penetrated over a dozen states, and even reached as far as the White House, which disclosed that an aide to Energy Secretary Steven Chu apparently got sick while helping arrange President Barack Obama’s recent trip to Mexico. They added however that the aide did not fly on Air Force One and never posed a risk to the president.

So far, the U.S. cases are fairly mild for the most part, with one death – a Mexican toddler who visited Texas with his family — unlike in Mexico where more than 160 suspected deaths have been reported. Apparently also, most of the U.S. cases so far didn’t need a doctor’s care.

Still, the U.S. is taking extraordinary precautions, including shipping millions of doses of anti-flu drugs to states in case they’re needed against what the World Health Organization has called an imminent pandemic, because scientists cannot predict what a brand-new virus might do. A key concern is whether this spring outbreak will resurge in the fall.

In terms of official Swine Flu numbers in the U.S., the CDC (Centers for Disease Control) confirms 109 cases and state officials confirm 19 more. CDC confirms: 50 in New York; 26 in Texas; 14 in California; 10 in South Carolina; two each in Kansas and Massachusetts; and one each in Indiana, Ohio, Arizona, Michigan and Nevada. State officials confirm five in New Jersey; four in Delaware; three additional cases in Arizona; two additional cases in California; two in Colorado; one additional case in Michigan; and one each in Georgia and Minnesota.
