â€œThe fluâ€ is an infection caused by the influenza virus. Flu symptoms include fever (usually 100?F to 103?F or > 37,8? C) in adults, and sometimes higher in children and problems such as cough, sore throat, runny or stuffy nose, headaches, muscle aches, fever and extreme tiredness.
Many people use the term â€œfluâ€ to mean any combination of these symptoms, such as the common cold, but true influenza infection is often worse and may last longer than a cold.
Flu outbreaks happen about once a year, usually in the winter, when the influenza virus spreads widely in the community. Outside of those outbreaks only a very tiny number of respiratory infections are caused by the influenza virus.
Should I get a flu shot?
TAMIFLU is not a substitute for a flu vaccination. If according to your health care professionalâ€™s advice you should continue to get a flu vaccination every year, TAMIFLU can be added if prescribed..
