Antigo (WAOW) -- The flu is becoming such an issue, across the country, the Centers for Disease Control and Prevention is now focused on the outbreak.
Experts say this is the worst flu season in three years. School leaders in Antigo are working with health officials to keep their students healthy.
"We have a great public health department that goes into every school and offers a flu clinic and the immunizations are free for any student who wants to take them with parental approval," said Antigo school nurse, Darlaen Jansen. "This year they immunized 564 kids in the school district which is about 30 percent of our student population."
Last week the CDC highlighted Wisconsin red on a U.S. map, which means the number of cases in our state are on the rise.
"But in our school district we have not yet seen a large amount of the influenza with the kids that need to stay home," Jansen said. "Most of the influenza swabs have been coming back negative."
Jansen encourages parents to make sure kids are eating healthy and staying hydrated.
"You use soap and friction and you wash really well and you do it for 20 seconds," Jansen said. "We also teach them to sneeze in their elbow."
Signs about covering your mouth when you cough and washing your hands regularly are posted throughout the school.
Maintenance staff makes sure things like door handles and sinks are very clean.
