Causes
Certain herpes viruses cause roseola. Children get it from the saliva of people who carry the infection. It can be spread by:
- Kissing or other close contact
- Droplets from coughs or sneezes
Risk Factors
Roseola is more common in children under 3 years of age. The risk is higher among children in close contact with one another.
Symptoms
Common symptoms are:
- A sudden, high fever:
- 103°F to 105°F (39.4°C to 40.5°C)—may cause seizures in some children
- Lasts 3 to 5 days
- A rose-colored rash:
- Starts within 3 days after the fever
- On the chest and belly first, then may spread
- Lasts for a few hours to a few days
- Does not itch
- Other symptoms:
- Swollen glands in the neck
- Fussiness
- Lack of hunger
Diagnosis
The doctor will ask about your child’s symptoms and health history. A physical exam will be done. This is enough to make the diagnosis.
Treatment
Roseola goes away on its own in a few days. The goal of treatment is to ease symptoms. The doctor may advise medicines to lower the child’s fever.
Prevention
The risk of roseola may be lowered by having children:
- Wash their hands often
- Stay away from other children who have it
