Just over a third of U.S. adults ages 18 to 65 got the flu shot during the 2012-2013 flu season, according to an analysis released on Tuesday, and if that trend holds for the current flu season, many adults may be at risk.
According to the U.S. Centers for Disease Control and Prevention, the most prevalent flu strain this season is H1N1 – the same strain that caused the 2009 pandemic and afflicts otherwise healthy children and young adults.
Flu is now widespread in 35 states, according to the CDC. Rates are particularly high in 13 states, mostly in the South and Southwest: Alabama, Arkansas, Indiana, Kansas, Louisiana, Mississippi, Missouri, Nevada, New Mexico, North Carolina, Oklahoma, Texas and Utah.
