Indiana State health officials say the number of flu deaths this season has jumped to 11. Only three deaths were reported last week. State health officials say six deaths of the deaths occured in northern Indiana's St. Joseph County. No other county has reported more than one death. State health commissioner William VanNess says this season's flu strains are hitting young and middle-aged adults fairly hard. The agency says all but one of Indiana's 11 flu deaths have been people between the ages of 25 and 64. The state had 27 flu deaths at the same time last year. Health officials still urge residents to get flu vaccinations since the flu season can last until April.
