The McLean County Health Department is asking the public to voluntarily limit hospital visits due a recent increase in influenza.
Sue Grant is a registered nurse with the department. She said February is often a peak month for flu activity.
"People bring the disease with them when they travel at the holidays, and people are in parties and bigger events and this time of year, everyone is inside and cooped up together. So you have close contact with more people and it's an easier spread for the flu that way," said Grant.
