What is the difference between a Cold and the Flu?

Maybe you did not get a flu vaccination, but got sick last season. Maybe you had the flu, maybe it was a cold. Did you know the difference? The common cold and the flu are both respiratory (breathing) infections caused by viruses. Some of the symptoms are similar, and it may be difficult to determine whether you have a cold or the flu. The Centers for Disease Control and Prevention (CDC) provides the following information about colds and the flu:

Colds

Colds usually begin slowly, between two and three days after infection by a virus. They normally last up to seven days. Symptoms often include:

• A scratchy, sore throat
• Sneezing and a runny nose.
• A mild cough may appear several days later.
• Adults and older children may experience a mild fever. Infants and young children can develop temperatures up to102o F.

The Flu

Flu symptoms are more serious and dangerous because of the chance of developing pneumonia. Symptoms of the flu include:

• Sudden headache
• Dry cough
• Achy muscles
• Fatigue
• Sometimes nasal congestion and sore throat.
• Fever as high as 104° F.

Some people with the flu feel better after several days, but fatigue and coughing can last for two weeks or longer.

The flu virus is easily passed through the air from person to person by coughing and sneezing. It may also be contracted by touching a surface contaminated with flu germs, such as a door handle, and then touching the eyes, nose, or mouth. Hand washing is an effective way to prevent spreading the virus, but vaccinations are the most effective way to reduce your chances of catching the flu.
If you do get the flu, some medications may help reduce discomfort ask your doctor what medications may help to relieve the symptoms of colds and the flu.

Empowerment Point

In general, the flu is worse than the common cold, and can lead to serious health problems, such as pneumonia, bacterial infections, or hospitalization. It is always best to consult your doctor and wash your hands often.
