The flu season runs from October through May and last season ended with 69 flu deaths in Indiana.

The Indiana State Department of Health says flu cases are rising in many parts of the state and four Indiana residents have died of influenza since October.

The Centers for Disease Control and Prevention (CDC) recommends the flu vaccine for everyone six months of age and older.

IU Health doctor says there are a number of reasons she is not recommending the mist.

The Marion County Health Department is seeing primarily Influenza A - but at this time of year they say you can see all kinds. H1N1 that circulated in 2009 is also showing up.
