Overview of Influenza/Flu
Seasonal 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:
- Muscle aches
- Fatigue or weakness
- Dry cough
- Less common symptoms: runny nose, sneezing, sore throat
- Annual flu shot or flu mist nasal spray is the most effective method of prevention.
- 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 (CDC recommends that people with influenza-like illness remain at home until at least 24 hours after they are free of fever (100° F / 37.8°C), or signs of a fever without the use of fever-reducing medications.)
- Cover your mouth with a disposable tissue when coughing and sneezing. Throw tissue in the trash can.
- Try to avoid close contact with sick people.
There is no cure for the flu. Antiviral medications may be useful for high-risk individuals. They may make influenza symptoms milder and may also prevent serious influenza complications. Antiviral medications are by prescription only. Contact the advice nurse or your provider for more information. Please note that Antibiotics do not work against viruses.
The following will help you feel better and treat your symptoms while your body fights off the virus:
