New swine flu cases in Europe, US, Latin America

The swine flu epidemic spread deeper into the United States, Europe and Latin America - and in Canada, back to pigs - even as Mexico's health chief hinted Sunday it may soon be time to reopen businesses and schools in the nation where the outbreak likely began. The virus spread to Colombia in the first confirmed case in South America, worrisome because flu season is about to begin in the Southern Hemisphere. More cases were confirmed in Europe and North America; the World Health Organization said at least 787 people have been sickened worldwide. Dr. Richard Besser, acting chief of the U.S. Centers for Disease Control and Prevention, said swine flu is spreading just as easily as regular winter flu, with 226 confirmed cases in 30 U.S. states. "The good news is when we look at this virus right now, we're not seeing some of the things in the virus that have been associated in the past with more severe flu," Besser said. "That's encouraging, but it doesn't mean we're out of the woods yet."
