Fever is the most common reason parents bring their child to see me. It is also the most misunderstood.

Almost every parent who walks into my clinic with a feverish child asks some version of the same question: is this dangerous? The answer, in the large majority of cases, is no. But knowing which cases are the exception is what matters — and that is what I want to explain here.

Fever is not an illness

This is the first thing I tell parents. Fever is a symptom, not a disease. It is the body's normal response to an infection, and in most cases it means the immune system is doing exactly what it should.A temperature above 100.4°F (38°C) is considered fever in children. But the number on the thermometer is far less important than most parents assume. A child with a temperature of 103°F who is drinking, playing, and alert is usually less concerning than a child at 100.5°F who is unusually drowsy and refusing feeds.How your child is behaving tells you more than the reading does.

What to do at home

For a child who is otherwise well and behaving normally:Dress them in light cotton clothing. Heavy blankets and layers trap heat and push the temperature higher — the belief that a child should be bundled up to "sweat out" the fever is one of the most persistent and unhelpful myths I encounter.Offer fluids frequently. Small, regular sips of water, milk, or ORS matter more than large amounts at once. Fever increases fluid loss, and dehydration is a genuine risk in young children.Sponge with lukewarm water if the child is uncomfortable. Never cold water or ice — cold triggers shivering, and shivering raises core body temperature further.Let them rest. Appetite often drops during fever, and that is normal for a few days.Give fever medication only in the dose your doctor has advised for your child's weight, and only when the child is genuinely uncomfortable. Medication is for comfort, not for chasing the number down.

When to see a doctor without delay 

Some situations need medical attention the same day, regardless of how high or low the temperature is:Any fever in a baby under three months. In very young infants, a fever can be the only sign of a serious infection. This is not a wait-and-watch situation.Fever lasting more than three days. Most viral fevers settle within this window. Beyond it, the cause needs to be identified.A child who is unusually drowsy, difficult to wake, or unresponsive. Lethargy is more significant than temperature.Refusing to feed or drink, or showing signs of dehydration — reduced urine output, dry mouth, no tears when crying.Difficulty breathing, rapid breathing, or chest indrawing.Fever with a rash, particularly with body aches — this can indicate dengue, which is common in Pune during and after the monsoon.A seizure during fever.Persistent vomiting or loose motions alongside fever.If any of these are present, do not wait to see whether it settles overnight.

On antibiotics 

Parents frequently ask me to prescribe an antibiotic when a child has fever. I usually do not, and it is worth explaining why.The overwhelming majority of childhood fevers are caused by viruses. Antibiotics have no effect on viruses. Giving them unnecessarily does not speed up recovery — it exposes the child to avoidable side effects and contributes to antibiotic resistance, which is a growing problem in India and one that will affect this generation of children as they grow up.When a bacterial infection is genuinely present, antibiotics are essential and I prescribe them without hesitation. The skill lies in telling the difference, which is what a clinical examination is for.

What matters most 

Watch your child, not the thermometer. A child who is alert, drinking, passing urine normally, and settling between temperature spikes is usually managing well. A child who seems unlike themselves — floppy, unusually quiet, refusing everything — needs to be seen, even if the fever seems mild.And if something feels wrong to you as a parent, it is worth getting checked. In my experience, a parent's instinct about their own child is often right.
