Influenza (Flu)

Overview

Flu is a contagious respiratory illness caused by an influenza virus. It is generally seen November thru March of each year.

Signs & Symptoms

Symptoms of flu are similar to those of a cold but are often more severe and start very suddenly. They usually develop 1-4 days after exposure and can last for several weeks. Most people feel better within a week but may have a lingering cough and fatigue. Symptoms may include:

  • Fever
  • Chills
  • Muscle aches
  • Headache
  • Fatigue or weakness
  • Dry cough
  • Less common symptoms: runny nose, sneezing, sore throat

Prevention

  • Annual flu shot or flu mist nasal spray is the most effective method of prevention. (NEW see Flu Vaccination Recommendations & Vaccination Clinic Dates 2007-2008)
  • Wash your hands frequently with soap and water.
  • Try not to touch your eyes, nose or mouth. Germs often spread this way.
  • Stay home when you are sick
  • Cover your mouth with a disposable tissue when coughing and sneezing
  • Eat well
  • Get plenty of sleep
  • Manage your stress
  • Drink lots of fluids
  • Get regular exercise
  • Avoid alcohol
  • Avoid smoking and smoky environments

Treatment

There is no cure for the flu. Antibiotics do not work against viruses. All you can do to feel better is treat your symptoms while your body fights off the virus.

  • Get lots of rest
  • Drink plenty of fluids
  • Inhale steam from a hot bath or shower to relieve congestion
  • Use hard candies and cough drops to soothe a dry throat
  • Gargle with warm salt water to soothe a sore throat
  • Avoid close contact with others
  • Avoid smoking, caffeine and alcohol
  • Over the counter medications (take as directed on the package):
    • Acetaminophen or ibuprophen for fever, body aches, headaches and sore throat
    • Robitussin DM for cough

Antiviral medications may help to decrease the severity and duration of the symptoms if taken within the first 2 days. These medications are by prescription only. Contact the advice nurse or your provider for more information.
