(FOX19) - Health officials revealed this flu season has become one of the worst outbreaks in several years.
During the last week of December 2012, flu cases were widespread in 41 states.
To date, seven people in Indiana have died of influenza, as well as one person in Kentucky.
Officials say the flu vaccine is well-matched to this year's reported flu strains. However, it still isn't 100% effective.
Should flu cases increase, UC Medical Center said visitation restrictions will be imposed, accordingly.
