May 4 (Bloomberg) — Swine flu has spread to 30 U.S. states and the number of countries with confirmed cases jumped to 20 from two in little more than a week. The expansion comes as Mexico’s president said his nation is winning the battle against the virus and may return to normal this week.

Officially called H1N1, the virus is probably circulating in “virtually all” U.S. states, Anne Schuchat of the U.S. Centers for Disease Control and Prevention said yesterday. First reported in the U.S. and Mexico, H1N1 also has been confirmed in Central America, Europe, the Middle East, Asia and New Zealand.
