Flu / Influenza Diagnosis, Testing, and Treatment

Influenza, more commonly known as the flu, is a contagious respiratory illness caused by the influenza virus. The best way to prevent the flu is by getting a flu vaccine each year. All persons age 6 months or older, including pregant women and people with chronic conditions, are recommended for annual vaccination. The flu vaccination is available in all of our Gwinnett Clinic locations!

People who have the flu often feel some or all of these symptoms:
  • Fever or feeling feverish/chills
  • Cough
  • Sore throat
  • Runny or stuffy nose
  • Muscle or body aches
  • Headaches
  • Fatigue (tiredness)
  • Some people may have vomiting and diarrhea, though this is more common in children than adults.

Symptoms alone are not enough to tell for certain if you have the flu. Your Gwinnett Clinic doctor will have tests done to know for sure. The most common flu test is called the rapid influenza diagnostic tests (RIDTs). These tests, as the name suggests, provide results very quickly within 10-15 minutes.

Once diagnosed, the flu can be treated with antiviral drugs. The most commonly prescribed antiviral drug being Tamiflu (oseltamivir). However, you should still plan to get the flu vaccine as antiviral drugs are not a substitue and the vaccine can prevent future illnesses due to the influenza virus. 

If you think you might have the flu, come see your Gwinnett Clinic doctor today!
