THE FLU and WHAT YOU NEED TO KNOW:

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 flu will have a fever.

Will my health care provider test me for flu if I have flu-like symptoms?

Not necessarily. Most people with flu symptoms are not tested because the test results usually do not change how you are treated.

Your health care provider may diagnose you with flu based on your symptoms and their clinical judgment or they may choose to use an influenza diagnostic test. During an outbreak of respiratory illness, testing for flu can help determine if flu viruses are the cause of the outbreak. Flu testing can also be helpful for some people with suspected flu who are pregnant or have a weakened immune system, and for whom a diagnosis of flu can help their doctor make decisions about their care.

Flu Treatment

If you get sick with flu, antiviral drugs may be a treatment option.
Check with your doctor promptly if you are at high risk of serious flu complications and you get flu symptomsPeople at high risk of flu complications include young children, adults 65 years of age and older, pregnant women, and people with certain medical conditions such as asthma, diabetes and heart disease.

When used for treatment, antiviral drugs can lessen symptoms and shorten the time you are sick by 1 or 2 days. They also can prevent serious flu complications, like pneumonia. For people at high risk of serious flu complications, treatment with antiviral drugs can mean the difference between milder or more serious illness possibly resulting in a hospital stay. CDC recommends prompt treatment for people who have influenza infection or suspected influenza infection and who are at high risk of serious flu complications.


What should I do if I get sick?


Most people with the flu have mild illness and do not need medical care or antiviral drugs. If you get sick with flu symptoms, in most cases, you should stay home and avoid contact with other people except to get medical care.

If, however, you have symptoms of flu and are in a high-risk group, or are very sick or worried about your illness, contact your health care provider.

Certain people are at high risk of serious flu-related complications (including young children, people 65 and older, pregnant women and people with certain medical conditions). This is true both for seasonal flu and novel flu virus infections. If you are in a high-risk group and develop flu symptoms, it’s best for you to contact your doctor early in your illness. Remind them about your high-risk status for flu. CDC recommends that people at high risk for complications should get antiviral treatment as early as possible, because benefit is greatest if treatment is started within 2 days after illness onset.
