Influenza, commonly known as the flu, is a respiratory illness caused by the influenza virus. It usually occurs during the winter season with the following common symptoms: fever, cough, sore throat, runny or stuffy nose, muscle or body aches, headache and fatigue (tiredness).

Influenza is a contagious disease which means that it can easily be spread from person to person. Widespread outbreaks can occur, leading to missed time at work and school. For the very young or old, as well as those with weakened health conditions, it can lead to hospitalization and even death.

The best protection from getting the flu is to receive the annual flu vaccine. You can get the flu vaccine through your doctor or local pharmacies. Those without Medical Assistance or insurance coverage should call the Rock County Public Health Department at 608-757-5440.
