Testing of positive cultures can reveal the type of influenza present, A, B, or C, and the strain. This information can be used to determine the contents needed for annual vaccines. Although antibiotics do not work on viruses, a practitioner may prescribe antiviral drugs, which may help lessen the duration and severity of influenza disease.
Practical treatments consist of getting plenty of rest and increasing fluid intake.
Taking over the counter medications for cough, pain relief, fever reduction, congestion and antihistamine, may provide some relief for certain individuals while the illness runs it s course. The primary method of preventing influenza illness, and its more severe complications, is by obtaining the influenza vaccine each year. During the influenza season, avoid exposure to others who are sick with influenza and cold symptoms as much as possible. Get optimal amounts of rest and exercise, and eat a well-balanced, nutritious diet daily. One of the simplest ways to prevent illness is to wash your hands before meals, and especially after encounters with those who are sick.
