Understanding the Common Cold -- the Basics
Common Cold Symptoms
When a cold strikes, you may have symptoms like:
- Scratchy or sore throat
- Stuffy nose
- Watery eyes
- Mucus draining from your nose into your throat
More severe symptoms, such as high fever or muscle aches, may be a sign that you have the flu rather than a cold.

Kids and Colds
Children have about 5-7 colds per year. A big part of the reason: They spend time at school or in day care centers where they're in close contact with other kids most of the day. And to top it off, their young immune systems aren't yet strong enough to fight off colds.

Preparing for Cold Season
In the U.S., most colds happen during the fall and winter. Beginning in late August or early September, the rate increases slowly for a few weeks and remains high until March or April, when it goes down. The reason may partly have to do with the opening of schools. Cold weather may also play a role because it leads you to spend more time indoors, where you're in closer contact with people who are contagious.
Changes in humidity in different seasons may also affect how often people get sick. The most common cold viruses survive better when it's low. Also, cold weather may make the lining of your nose drier and more vulnerable to an infection by a virus.
When to Call the Doctor About a Cold
Most colds last about 7 to 10 days, but if your symptoms linger, you may need to call the doctor. Sometimes, colds lead to an infection by bacteria in in your lungs, sinuses, or ears. If that happens, your doctor may prescribe antibiotics, which work against bacteria but not against viruses.
