Never give aspirin to children. Drink lots of liquids, such as fruit juice, hot tea, chicken soup. Never use ice water or rubbing alcohol. Don't over-bundle in blankets. These infections are called secondary, because they are not truly a symptom of the flu, but develop because your body is in a weakened state and cannot fight them off.
Secondary infections require different treatment than the flu.
Prevention Most cases of flu can be prevented. In the elderly and in people with certain chronic illnesses, the vaccine may not prevent illness altogether, but it can reduce its severity and the risk of complications. The vaccine is made from egg-grown viruses and is noninfectious. This means you can't get the flu from the shot. Your immune system needs six to eight weeks to respond to the vaccination, so getting a flu shot after your child comes down with the flu is not going to help you.
