Influenza (Flu)

What is Influenza (Flu)?

Flu is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness.
 

Common Flu Signs & Symptoms

Flu signs and symptoms usually come on suddenly. People who are sick with 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.
*It’s important to note that not everyone with the flu will have a fever.
 

Preventive actions to stop the spread of germs:

  • Try to avoid close contact with sick people.
  • While sick, limit contact with others as much as possible to keep from infecting them.
  • If you are sick with flu-like illness, stay home for at least 24 hours after your fever is gone (without using fever-reducing medications) except to get medical care or for other necessities.
  • Cover your nose and mouth with a tissue when you cough or sneeze. After using a tissue, throw it in the trash and wash your hands.
  • Wash your hands often with soap and water. If soap and water are not available, use an alcohol-based hand rub.
  • Avoid touching your eyes, nose and mouth. Germs spread this way.
  • Clean and disinfect surfaces and objects that may be contaminated with germs like flu.
