Flu Outbreak Spreads Across US, Affects Young Adults

Ten states reported widespread flu activity this week, mostly in the Southeast, but flu is now fanning across the rest of the nation, according to the weekly report issued by the Centers for Disease Control and Prevention.

And it’s a once-familiar strain — the H1N1 virus that plagued the country in 2008-09. “It’s our old swine flu friend and it’s causing over 95 percent of the cases,” said Dr. William Schaffner, infectious disease specialist at Vanderbilt University.
