A five-year-old with four days of fever at 5 pm on a Friday

This is a febrile child with an upper respiratory illness who is physiologically stable. Using a traffic-light approach, he has no red or amber features: he is alert, responsive, has normal colour, moist mucous membranes, normal capillary refill, no respiratory distress and no non-blanching rash. His heart rate and respiratory rate are within the range expected with fever at this age, and SpO2 is normal. Four days of fever with coryza is typical of a viral illness; antibiotics would not shorten it and would add resistance and adverse-effect risk.

Immediate management is therefore supportive and observational, not interventional:

• Antipyretics for comfort, with correct weight-based dosing, and fluids.
• Examine specifically for otitis media, pneumonia, urinary infection and streptococcal pharyngitis; document that these were considered and are absent.
• A urine sample is reasonable if there is any urinary symptom or if fever persists without a focus, but routine blood tests, inflammatory markers and chest X-ray are not indicated in a well child with a clear source.
• The real risk here is the weekend and the distance to hospital, so the safety net must be specific rather than "come back if worse".

Safety-netting works only if it is specific, understood and recorded. Generic advice is not enough, especially for an anxious mother who has read about sepsis and lives 40 minutes from an emergency department.

I would give written instructions stating exactly what to look for:

• Fever lasting five days or more, or fever that settles and then returns.
• Breathing faster, drawing in between the ribs, grunting, or lips looking blue.
• A rash that does not fade when pressed with a glass.
• Drowsiness, confusion, poor responsiveness, or a seizure.
• Not drinking, no urine for eight hours, or vomiting everything.
• Severe headache, neck stiffness, or a bulging fontanelle (not applicable at five, but parents often ask).

I would state where to go and when: the emergency department for any of the above, and our clinic or a 24-hour outpatient service otherwise. I would confirm the mother can repeat the plan back, check she has a thermometer and transport, and document the discussion. I would also arrange a review within 48–72 hours rather than leaving it open-ended, because persistent fever after day five changes the differential towards pneumonia, urinary infection or Kawasaki disease and warrants reassessment.

I would not dismiss the request; it comes from fear rather than from a wish to over-medicate. The mother has read about sepsis and has correctly identified fever as a warning sign, so I would validate that instinct and then explain why the tests she is asking for would not help.

• Antibiotics: this is almost certainly viral. Giving them would not reduce the fever, would not prevent sepsis, and would risk diarrhoea, allergy and resistance. I would explain that the decision is based on his examination and observations, not on withholding treatment to save money.
• Blood tests: a full blood count and CRP in a well child with a clear viral source rarely change management and can be falsely reassuring or falsely alarming; a normal result does not exclude serious illness, and the decision to seek help should rest on clinical features.
• I would spend time on what would actually make a difference: fluids, antipyretics, and the specific review plan.

If she remains very anxious, I would offer an earlier face-to-face review rather than a test, and document that she was heard. If at any point the child developed red features, the plan would change immediately to emergency referral.
