Red flags & when to go in person for Roseola (Infant) - Triage

Audience: adult

Roseola is a common viral illness in infants and young children that usually causes a sudden high fever followed by a rash. It often resolves on its own without serious complications. However, some symptoms may signal the need for urgent in-person medical care. This guide helps adults recognize when to seek immediate help for an infant with suspected roseola. Telemedicine can support initial assessment and advice but cannot replace hands-on examination when red flags appear. Understanding these warning signs helps keep infants safe while using telehealth services effectively.

What is Roseola?

Roseola is a viral infection mostly affecting infants aged 6 months to 2 years. It typically starts with a sudden high fever lasting 3 to 5 days. Once the fever goes down, a pinkish rash appears, usually starting on the trunk and spreading to the limbs and neck. The rash is not itchy and fades within a few days. Most children recover fully without treatment.

How long does roseola last?

The fever phase usually lasts 3 to 5 days, followed by a rash that fades in 1 to 3 days. Most infants recover fully without complications.

Can roseola be treated at home?

Yes, most cases are managed at home with fever control, fluids, and rest. However, watch for red flags that need medical attention.

When should I take my infant to the emergency room?
