The Centers for Disease Control says the flu has now reached epidemic levels in 37 states including Wisconsin. As of last week, there were more than 450 people hospitalized with the flu.
With the season expected to peak in just a few weeks, health experts are offering advice on how to avoid getting sick.
"Number one, get the vaccine. Number two, wash your hands. Soap and water first. Hand sanitizer second. Number three, no sharing common things we share in households. Water bottles, silverware, cooking utensils, those sorts of things," said Dr. Luann Moraski.
The majority of people who've been hospitalized with the flu have been 65 and older.
