Prevention and Control of Communicable Diseases
Roseola
Roseola is a common rash illness that usually occurs in children under 4 years of age. It is the most common cause of rash in children 6 months to 2 years of age.
Cause
Human herpesvirus 6.
Symptoms
Usually a high fever that appears suddenly and generally lasts 3 to 7 days. As the fever breaks, a rash appears on the trunk and neck and may later spread to the rest of the body. The rash may last from several hours to several days. At this time, the child usually does not feel very sick. Infection also occurs without symptoms in many children. Seizures may occur in children with high fevers.
Persons with weakened immune systems may have more severe disease and symptoms may last longer.
Spread
Most likely person-to-person through respiratory secretions.
Incubation
Estimated to be 9 to 10 days.
Contagious Period
Most likely during the fever and before the rash appears.
Exclusion
Child Care: Until fever is gone and other rash illnesses, especially measles, have been ruled out.
Diagnosis
Recommend parents/guardians call their healthcare provider if their child has fever and rash.
Treatment
None.
Prevention/Control
- Regular and thorough handwashing is the best way to prevent the spread of communicable diseases. Wash hands thoroughly with soap and warm running water after touching anything contaminated with secretions from the nose and mouth and before preparing or eating food.
- Clean and sanitize mouthed objects and surfaces at least daily and when soiled.
