One "gift" we'd all like to avoid this holiday season is the gift of germs. As the cold and flu season swings into high gear, it's important to be aware that as you age, your body has a harder time fighting off infection. Once you have a cold or the flu, there is a greater chance that it will develop into a more serious illness.

A cold versus the flu
The following are symptoms of both colds and flu:

• Sore throat
• Runny nose and sneezing
• Headache
• Overall sick feeling
• Low-grade fever

The flu is more likely to lead to pneumonia. A cold usually does not cause high fever, while the flu can. A fever above 101 degrees is usually considered high. Also, a stuffy nose is probably a sign of a cold, rather than the flu. Overall, cold symptoms are milder and do not last as long as flu symptoms.

Cozy up to self-care
Because colds and flu are caused by viruses, there is no cure. Pamper yourself by resting and drinking plenty of fluids. Talk with your doctor about over-the-counter medicines that may help ease your symptoms.

Know when to see your doctor
The following symptoms may indicate a problem more serious than a common cold or the flu:

• Chest pain
• Wheezing
• A high fever
• Shaking chills with intermittent sweating
• Frequent colds
• Shortness of breath that comes with little or no exertion
• Phlegm or mucus produced for two or more weeks
• A cough that lasts two weeks or produces blood

A persistent cough with a fever and chills, for instance, could be a sign of pneumonia. See your doctor right away if you have any of these symptoms or if any symptoms last longer than usual for a common cold or the flu. The earlier you catch problems, the more easily they can be treated.

Prevention tips

• Cover your mouth and nose (not with your hand) when you cough or sneeze.
• Wash your hands or use alcohol-based hand cleaner often.
• Carry disinfectant wipes to wipe off shared surfaces -- grocery cart handles, door handles, etc.
• Avoid sharing cups, utensils and towels with people who are sick.
• Eat a healthy diet, drink enough water, manage your stress and get enough sleep.
