The common cold is a viral infection of your nose and throat (upper respiratory tract). It's usually harmless, although it might not feel that way. Many types of viruses can cause a common cold. Children younger than six are at greatest risk of colds, but healthy adults can also expect to have two or three colds annually. Most people recover from a common cold in a week or 10 days. Symptoms might last longer in people who smoke. If symptoms don't improve, see your doctor.
Avoid the Antibiotics! More than 300 different viruses can cause colds, so each time you have a cold it is caused by a distinct virus (i.e. adenovirus, rhinovirus, parainfluenza virus, coronavirus). A virus is much smaller than a bacteria; it is a tiny cluster of genetic material surrounded by a protein wrapper.
