Influenza, also called "the flu," is a viral infection that mainly affects the respiratory tract. This includes the lungs, nose, and throat. The flu spreads easily from person to person (is contagious). It causes common cold symptoms, along with high fever and body aches.
If the flu is diagnosed early, you can be treated with antiviral medicine that is given by mouth (orally) or through an IV. This can help reduce how severe the illness is and how long it lasts.
In many cases, the flu goes away on its own. If you have severe symptoms or complications, you may be treated in a hospital.
