Red flags & when to go in person for Fever Without Source (Child) - Triage

Audience: pediatric

Fever without a clear source in children means a child has a fever but no obvious cause like a cold or ear infection. This can be common but sometimes signals a more serious illness. Telemedicine can help assess symptoms and guide parents on care steps. However, certain warning signs mean your child needs to be seen in person quickly. These include difficulty breathing, persistent vomiting, unusual sleepiness, or a rash that does not fade when pressed. Knowing when to seek in-person care helps keep your child safe. This guide explains red flags, what telemedicine can and cannot do, and how to prepare for a virtual visit. Always trust your instincts and seek urgent care if your child looks very unwell.

Red flags — go in person / ER

What telemedicine can do
