About This Topic

Symptoms

  • Most children get Roseola between 6 months and 3 years of age.
  • Rash: Pink, small, flat or slightly raised spots on the chest and stomach. Rash is the same on both sides of the body. Then may spread to the face and arms.
  • Classic feature: 3 to 5 days of high fever without a rash or other symptoms.
  • The rash starts 12 to 24 hours after the fever goes away.
  • The rash lasts 1 to 3 days.
  • By the time the rash appears, the child feels fine.

Causes

  • Human herpes virus 6 (HHV6)

Viral Rashes and Drug Rashes

  • Prescription medicines sometimes cause widespread rashes.
  • Non-prescription (OTC) medicines rarely cause any rashes.
  • Most rashes that occur while taking an OTC medicine are viral rashes.
  • Fever medicines (acetaminophen and ibuprofen) cause the most confusion. Reason: Most viral rashes start with a fever. Hence, the child is taking a fever medicine when the rash starts. But the fever medicine had nothing to do with the rash.
  • Drug rashes can't be diagnosed over the phone.

Prevention

  • Good hand washing can prevent spread of infection.
