roseola infantum,
a benign viral endemic illness of infants and young children, caused by human herpesvirus 6 (of which there are two strains, A and B) and possibly by herpesvirus 7. It is characterized by abrupt, high, sustained or spiking fever, mild pharyngitis, and lymph node enlargement. Febrile seizures may occur. After 4 or 5 days the fever suddenly drops to normal, and a faint, pink, maculopapular rash appears on the neck, trunk, and thighs. The rash may last a few hours to 2 days. Diagnosis is based on high fever and the rash. Sequelae may occur as a result of the seizures. There is no specific therapy or vaccine. Acetaminophen is often used to try to control fever. Also called exanthema subitum, sixth disease, Zahorsky's disease.

2. roseola infantum.
roseola infan´tum a common acute disease caused by infection with the herpesvirusRoseolovirus. It usually occurs in children under two years old, coming on suddenly and disappearing in 3 to 5 days, leaving no permanent marks. Diagnosis is difficult because the sole early symptom, beyond irritability and drowsiness, is fever. There may be convulsions, and generally the fever is very high; 40°C (104°F) is not unusual. Despite the high fever, the disease is mild. Called also exanthem subitum.
As the fever subsides and the disease is apparently at an end, a rash breaks out, usually on the body. This is unlike the course of other childhood diseases such as measles, scarlet fever, and chickenpox, in which the rash is present during the most intense phase; the rash of roseola infantum lasts only a few days and may disappear within hours (often it is so transitory that it is missed). Treatment consists only of such standard measures as antipyretics and tepid sponge baths to allay the fever. Rest and fluids are also recommended.
Once it is over, the child is believed to be permanently immune from further attacks. Roseola is sometimes confused with rubella, but is distinguished by having no lymph node involvement. Blood antibody titers are sometimes used when symptoms appear, to determine which disease it is.
