Do I Have the Flu?

The flu and the common cold are both respiratory illnesses but they are caused by different viruses. Because these two types of illnesses have similar flu-like symptoms, it can be difficult to tell the difference between them based on symptoms alone. Within the first few days of illness, special tests may be carried out, when needed, to tell if a person has the flu.

In general, the flu is worse than the common cold, and symptoms such as fever, body aches, extreme tiredness, and dry cough are more common and intense.

Colds are usually milder than the flu. People with colds are more likely to have a runny or stuffy nose. Colds generally do not result in serious health problems, such as pneumonia, bacterial infections, or hospitalizations.

Diagnosing the Flu:²
It is very difficult to distinguish the flu from other infections on the basis of symptoms alone. A doctor's exam may be needed to tell whether you have developed the flu or a complication of the flu. There are tests that can determine if you have the flu as long you are tested within the first 2 or 3 days of illness.

If you develop flu-like symptoms and are concerned about your illness, especially if are at high risk for complications of the flu, you should consult your healthcare provider. Those at high risk for complications include people 65 years or older, people with chronic medical conditions, pregnant women, and young children.

Antiviral Medications:^2,3
Your doctor may recommend use of an antiviral medication to help treat the flu. These are prescription medications, and a doctor should be consulted before the drugs are used. Antiviral treatment is usually taken for 5 days and work best if they are started within two days of getting sick. Therefore, if you get flu-like symptoms, seek medical care early.

Other Ways to Respond to the Flu:⁴
If you get the flu, get plenty of rest, drink a lot of liquids, and avoid smoking. Also, you can take medications such as acetaminophen to temporarily reduce fever and relieve muscle aches and pains associated with the flu. Never give aspirin to children or teenagers who have flu-like symptoms, particularly a fever.
