When Is a Baby's Fever an Emergency?
Not every fever is an emergency — but some are. An age-by-age guide for Pakistani parents, with dengue and drug-resistant typhoid in mind.
When Is a Baby's Fever an Emergency?
A warm forehead sends most parents into a spin, but fever itself is not the enemy — it is the body fighting infection. What matters far more is your baby's age, how they are behaving, and, in our climate, which infections are going around.
Age changes the rules
- Under 3 months: any fever (38°C / 100.4°F or above) is a "go now" situation, even if the baby looks well. Small babies can hide serious infection, so this one is not for watching at home.
- 3 to 6 months: get advice the same day if the fever is high or won't settle.
- Older babies: how they look and act matters more than the number on the thermometer.
Use paracetamol only in the amount your doctor or the bottle sets for your baby's weight, and mainly for comfort — never give aspirin to a child, and avoid ibuprofen if dengue is possible (see below).
Watch the child, not just the thermometer
Go to a doctor or hospital straight away if, along with the fever, your baby:
- Is hard to wake, floppy, or unusually drowsy
- Is breathing fast or struggling to breathe
- Has a fit or convulsion
- Has a rash that does not fade when you press a glass against it
- Won't feed, has a dry mouth and far fewer wet nappies, or a bulging or sunken soft spot
- Simply looks, to you, seriously unwell — trust that instinct
Two local infections to keep in mind
Dengue. From the monsoon through autumn (roughly July to November), dengue spreads across our cities. Suspect it with high fever and body aches, and watch for warning signs: bad tummy pain, repeated vomiting, bleeding gums or nose, blood in vomit or stool, cold clammy skin, or a suddenly quiet, listless child. These need hospital assessment — and this is exactly why aspirin and ibuprofen are avoided when dengue is possible, as they raise the risk of bleeding.
Typhoid. Pakistan is living with a drug-resistant (XDR) strain of typhoid, especially out of Sindh, that shrugs off the older antibiotics. A fever that climbs and lingers for several days, with poor appetite and tummy upset, deserves a proper assessment and possibly a test — don't dose a stubborn fever with leftover antibiotics from the medical store. The typhoid vaccine (TCV) in the EPI schedule is your best shield.
Helping at home while you decide
- Offer plenty of feeds — breast, formula or water by age — to keep fluids up.
- Dress the baby lightly and keep the room airy; don't bundle a hot baby in blankets.
- A lukewarm sponge can comfort; skip cold water, ice and rubbing alcohol.
You know your baby's normal better than anyone — when your gut says something is off, that alone is reason enough to ring your paediatrician.
