When to See a Doctor for Flu
Most flu cases resolve at home with rest, but certain warning signs warrant prompt medical attention.
Warning signs warranting prompt medical attention
- Difficulty breathing or shortness of breath
- Persistent chest or abdominal pain or pressure
- Sudden dizziness, confusion, or difficulty waking
- Severe or persistent vomiting
- Symptoms that improve then return with worsening fever or cough
- High-risk individuals (very young children, elderly, pregnant, immunocompromised) with any flu symptoms
This list reflects general public health guidance and is not exhaustive. If in doubt, contact a healthcare provider — erring on the side of caution costs little compared to a delayed response to a serious complication. From a workplace perspective, err on the side of a longer recovery period; see our sick leave policy guide for structuring flexible entitlement that doesn’t pressure a premature return.
