(UNDATED) - Flu season is ramping up. It's now widespread in at least 35 states, including Indiana--up from 25 in the previous week.
This year's strain is particularly aggressive, but officials at the Centers for Disease Control estimate only a 45 percent vaccination rate nationwide.
Indiana has reported three flu deaths so far this season, and Indiana Department of Health leaders expect that number to go up. Last season the state reported more than 70 flu-related deaths.
