Roseola infantum
|
|
Roseola infantum A common viral illness in children under 2, roseola infantum begins with a high fever, runny nose, and swollen glands, usually followed by a rash on the torso, arms, or legs. While the infection is common, serious complications from roseola infantum are rare.
RELATED TERMS--------------------------------------
Fever
When body temperature rises above its normal level - defined as 98.6 degrees F, though it varies by individual and time of day. A fever is the sign of an immune system at work and usually indicates an infection.
Rash
A reddish spot or patch of irritated skin. Rashes can be caused byillnesses, allergies, and heat and are usually temporary.
Arms
An appendage in anatomy and in clinical trials. See: Arm.
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.
