Causes    TOP

Certain herpes viruses cause roseola. These are different than those that cause cold sores. Your child gets it from the saliva of people who carry the infection. This can happen through kissing or other close contact.

Risk Factors    TOP

Roseola is more common in children under 3 years old. Older siblings in the same home make the chances of infection higher.

Symptoms    TOP

Common symptoms include:

  • A sudden, high fever:
    • 103°F-105°F (39.4°C-40.5°C)—may cause seizures in some children
    • Lasts 3-5 days
  • A rose-colored rash:
    • Starts within 3 days after the fever stops
    • Appears on the chest and abdomen first, then may spread
    • Lasts for a few hours to a few days and does not itch
  • Other symptoms:
    • Swollen lymph nodes in the neck
    • Irritability
    • Poor appetite

Diagnosis    TOP

The doctor will ask about your child’s symptoms and health history. The presence of a rash after a high fever is a sign of the illness. The doctor diagnose it with this information and a physical exam. Testing is not required.

Treatment    TOP

Roseola goes away on its own without problems. The focus of care is to ease symptoms. Medicines help lower your child’s fever.

Note : Don’t use aspirin for children who have or had a viral infection. Check with the doctor before giving your child aspirin.

Prevention    TOP
