Roseola (also known as sixth disease, exanthema subitum, roseola infantum, baby measles, or three day fever) is a type of viral infection that is characterized by a sudden onset of high fever followed by a rash. Roseola is caused by two forms of the herpes virus. The infection can occur at any time of the year and usually is not serious.
Roseola is a common infection that is rare in adults and usually affects young children between the ages of six months and three years. Approximately 77 percent of children develop roseola by two years of age.
Treatment is usually supportive and aimed at relieving symptoms until the infection clears on its own. Some doctor's may prescribe the antiviral medication ganciclovir (Cytovene®) for patients with weak immune systems. The infection usually goes away within one week of developing a fever.
