Common Cold

Definition

The common cold generally involves a runny nose, nasal congestion, and sneezing. You may also have a sore throat, cough, headache, or other symptoms. Over 200 viruses can cause a cold.

Symptoms

The three most frequent symptoms of a cold are:

• Nasal congestion
• Runny nose
• Sneezing

Adults and older children with colds generally have a low fever or no fever. Young children, however, often run a fever around 100-102°F.

Once you have "caught" a cold, the symptoms usually begin in 2 or 3 days, though it may take a week. Typically, an irritated nose or scratchy throat is the first sign, followed within hours by sneezing and a watery nasal discharge.

Within 1 to 3 days, the nasal secretions usually become thicker and perhaps yellow or green. This is a normal part of the common cold and not a reason for antibiotics.

Depending on which virus is causing the symptoms, the virus might also cause:

• Cough
• Decreased appetite
• Headache
• Muscle aches
• Postnasal drip
• Sore throat

Still, if it is indeed a cold, the main symptoms will be in the nose.

For children with asthma, colds are the most common trigger of asthma symptoms.

Colds are commonly seen before ear infections. However, a child's eardrums are usually congested during a cold, and it's possible to have fluid buildup without a bacterial infection (caled serous otitis media).

The entire cold is usually over all by itself in about 7 days, with perhaps a few lingering symptoms (such as cough) for another week. If it lasts longer, see your doctor to rule out another problem such as a sinus infection or allergies.
