Dengue in Children: Signs Parents Miss and When to Rush In
Children with dengue can look almost fine, playing and chatting, and then crash within hours, usually as the fever comes down. Watch their urine, their energy, their hands and their tummy, give paracetamol only (by weight, from the pack or a pharmacist), and rush to hospital the moment a warning sign appears.
In brief, for tired parents
- Riskiest days: about day 3 to day 7, often right after the fever settles.
- Quietest warning sign: passing much less urine than usual.
- Fever medicine: paracetamol only, dose by weight from the pack, pharmacist or doctor. Never ibuprofen or aspirin.
- Babies under 3 months: any fever means a doctor the same day, dengue season or not.

Why do parents miss dengue warning signs in children? Children are brave in the wrong way. A seven-year-old with a falling fever wants to get up and watch cartoons, and a toddler can’t tell you their tummy hurts or that they feel dizzy. They compensate: their hearts beat faster and their bodies hold the blood pressure steady for longer than an adult’s would, and then, when they can’t compensate any more, they drop quickly. This guide sits in our Barsaat and Flood Season series and covers what to watch, age by age, and exactly when to go.
What do dengue warning signs look like in a child?
The list is the same as for adults, but children show it differently, so here it is in child terms. Any one of these means hospital now:
- Much less urine. A dry nappy for 6 to 8 hours in a baby, or an older child who hasn’t passed urine since the morning.
- Unusually sleepy, floppy or hard to wake, or the opposite: irritable, restless, crying and impossible to settle.
- Cold hands and feet while the body feels normal or cool, with pale, damp or blotchy skin.
- Tummy pain that keeps coming back, a child who guards their belly, or a baby who cries when the tummy is touched.
- Vomiting again and again, or refusing all drinks.
- Any bleeding: gums, nose, blood in vomit or black stool, or new spots and bruises.
- Fast breathing, grunting or the chest sucking in with each breath.
Go to the hospital emergency department straight away, or call your local emergency number (1122 in Pakistan, 112 in India), for any sign in the list above, a fit, a stiff neck, or any fever in a baby under 3 months. See a doctor the same day for a fever of 39 °C or more in an unwell child, a fever lasting more than 3 days, or if your gut tells you something is wrong. Bring the blood reports and every medicine or syrup the child has had.
Dengue by age: what changes for babies, toddlers and older children
Under 6 months
Any fever under 3 months is a same-day doctor visit. Full stop. Keep breastfeeding or formula feeding often and give nothing else, not water, gripe water, ghutti or herbal drops, and count wet nappies, because that’s the clearest window you have into how much fluid is getting in.
6 to 12 months
Babies this age get dehydrated quickly and can’t tell you anything, so a baby who feeds poorly, has fewer wet nappies or seems unusually quiet needs a doctor that day. Keep breastfeeding and offer the usual feeds, with ORS in small sips if the doctor advises it.
1 to 3 years
Toddlers are the hardest to read, so watch their play: a toddler who normally climbs everything and now lies still on the sofa for hours is telling you something. Cold hands and a drop in wet nappies are your two most useful checks.
3 to 6 years
Children this age can point to a sore tummy but often call every pain “stomach ache”, so take it seriously if it keeps returning or if they won’t let you press the belly. Ask simply: “Did you do su-su today?”
Over 6 years
Older children can describe dizziness, pain and thirst, but they also hide symptoms to avoid injections or to get back to school. Ask directly, and check the toilet trips yourself.
Fluids: how to keep a child going at home
Small and often wins. A few sips every few minutes, from a spoon, a cup or a small bottle, adds up across the day far better than a big glass the child refuses. Breastfed babies keep breastfeeding, while older children can have ORS, water, lassi, daal ka pani, soups, coconut water and fresh juice. Make ORS from a pharmacy sachet exactly as the pack says, or use the WHO home mix of 1 litre of clean boiled and cooled water, 6 level teaspoons of sugar and half a level teaspoon of salt, as described in Bachon Mein Dast (Loose Motions): ORS by Age and Dehydration Signs. Too much salt is harmful, so measure with a proper teaspoon and level it off.
A child who refuses every drink, or vomits everything back, can’t be kept safe at home. That child needs a drip. Go.
Paracetamol only, and only by weight
For fever and body ache in suspected dengue, paracetamol is the only fever medicine to use in children. The dose is worked out from your child’s weight, so read the pack carefully or ask the pharmacist or doctor, and use the measuring syringe that came with the bottle rather than a kitchen spoon.
Never give ibuprofen or aspirin in dengue. Ibuprofen can raise the bleeding risk and upset the stomach, and aspirin is never given to children under 16 at all. Check every other syrup in the house too, because cough and cold mixes often contain paracetamol, which makes an accidental double dose easy, and over-the-counter cough and cold medicines aren’t for under-6s in any case.
Paracetamol makes a child more comfortable, but it doesn’t shorten dengue, and a fever that comes down with it is no sign of safety on its own. For general fever care by age, including sponging, see Bachon Ka Bukhar (Fever) by Age.
Count the wet nappies and the toilet trips. They tell you more than the thermometer.
Myth: “My child is playing, so it can’t be serious”
Play is reassuring, and most children with dengue recover well, but it isn’t a guarantee. Not in the critical phase. Children hold their blood pressure up until late, so a child can seem cheerful in the morning and be cold and drowsy by evening. Keep watching through the 48 hours after the fever breaks, keep the blood tests the doctor asked for, and don’t let a good morning cancel an afternoon check.
What elders often suggest, and what’s safe
Grandmothers reach for papaya leaf juice, goat milk, kiwi and pomegranate when a child’s platelets fall. Fruit and milk are fine as normal food for a child who is already eating, but none of them is a dengue treatment, and bitter leaf juices can make a child vomit, which is the last thing you want when every sip counts and the doctor is trying to judge how much fluid is staying in. Honey is never given to babies under 1 year. No ghutti under 6 months.
Dengue in children: questions parents ask
What are the warning signs of dengue in children?
Passing much less urine, unusual sleepiness or restlessness, cold hands and feet, repeated tummy pain, vomiting again and again, any bleeding and fast or noisy breathing. Any one of them means go to hospital now.
Can children with dengue be given ibuprofen?
No. Use paracetamol only, dosed by your child’s weight from the pack or by a pharmacist or doctor. Ibuprofen can raise the bleeding risk, and aspirin is never for children under 16.
How can parents tell if a child is dehydrated in dengue?
Fewer wet nappies or toilet trips, a dry mouth, no tears when crying, sunken eyes and, in babies, a sunken soft spot. No urine for 6 to 8 hours needs hospital.
Is dengue over once a child’s fever has gone?
Not necessarily. The riskiest time is often just after the fever settles, so keep watching closely for at least 48 hours and follow up with the doctor.
How much should a child drink in dengue?
Enough to keep passing urine regularly. Offer small sips every few minutes and ask your doctor for an amount suited to your child’s age and weight.
Is dengue more dangerous in children?
Children, especially babies, can get worse faster and show fewer clear signs, so they need earlier medical checks. Most still recover well with good care.
Can a baby get dengue?
Yes. Any fever in a baby under 3 months needs a doctor the same day.
Should breastfeeding continue if a baby has dengue?
Yes. Breastfeeding is the best fluid a baby can get, so feed often and tell the doctor if the baby feeds less than usual.
Does papaya leaf juice help children with dengue?
It isn’t a proven treatment, and its bitterness can trigger vomiting. Don’t give it to babies, and ask the doctor before giving any herbal drink to an older child.
When can a child go back to school after dengue?
When the fever has been gone for a couple of days, energy is returning and the doctor is happy with the blood count. Tiredness can linger for a week or two.
How can children be protected from dengue mosquitoes?
Full sleeves, a net for daytime naps, a child-suitable repellent used as the label says, and emptying standing water around the home every week.
