  Cold, common



Cold, common

   A viral upper respiratory tract infection. This contagious illness can be caused by many different types of viruses, and the body can never build up resistance to all of them. For this reason, colds are a frequent and recurring problem. In fact kindergarten children average 12 colds per year, while adolescents and adults have around seven colds per year.

RELATED TERMS
--------------------------------------

Infection
Anything that invades the body and reproduces. Infections can be bacteria, protozoa, fungi, or viruses. Bacteria and fungi are one celled creatures that cause many infections including strep throat, bladder infections, and some lung infections. Fungi cause “athlete’s foot” and thrush, an infection in the mouth. Protozoa are small organisms with many cells that can cause infections in the guts or in the lungs. Most healthy people do not get protozoal infections, but people with suppressed immune systems can. Viruses are not really organisms; they are tiny particles that can live only inside another cell. They reproduce by taking over a cell and causing that cell to make more virus particles, rather than doing what the cell is supposed to do. Viruses cause most colds and flu cases.

Contagious
Easily transmitted by direct or indirect contact.
