Fever
Fever is the body's normal infection response, not an illness itself — which is why the number on the thermometer matters less than age, duration, and what comes with it. Here's the decision logic, per NIH guidance.
Ride it out when
An otherwise healthy adult or older child has a fever under roughly 103°F, is drinking fluids, and has no severe symptoms. Rest, fluids, and standard fever reducers are the whole playbook; most viral fevers resolve within three days.
Urgent care when
A fever persists past about three days, improves then rebounds (a secondary-infection pattern), comes with sore throat or ear pain worth testing, or you're in a higher-risk group where a flu test inside the 48-hour antiviral window changes treatment.
ER when
The patient is an infant under 3 months with 100.4°F+ (always, no exceptions), there's a stiff neck, confusion, trouble breathing, a first-time seizure, or a rash that doesn't blanch under pressure.
- Under 3 months old with ≥100.4°F
- Stiff neck or confusion
- Non-blanching rash
