Chickenpox in children: what to expect, what helps, and what not to apply

How it goes

It starts like a mild viral illness — fever, tiredness, poor appetite — a day or two before the rash. The rash arrives in crops: flat red spots that become raised, then fluid-filled blisters, then crust over. New crops keep appearing for three to five days, so a child usually has spots at every stage at once, which is the classic sign.

It is highly infectious from about two days before the rash until every blister has crusted, usually five to seven days after the rash starts. That is when a child can return to school.

It spreads through the air and through contact with the blisters. In a household, siblings usually get it about two weeks later.

What helps

Paracetamol for fever and discomfort at the weight-correct dose. Do not give ibuprofen in chickenpox — it has been linked to serious skin infections in this illness specifically. Never give aspirin to a child.

For the itch: cool baths, calamine lotion, loose cotton clothes, and an antihistamine at night if your doctor advises one. Keep nails cut very short and consider mittens for a small child — scratching is what causes scarring and skin infection.

Fluids matter more than food. Blisters in the mouth make eating painful, so offer cool, soft, bland things — curd, khichdi, kheer, ice lollies — and plenty to drink.

Do not apply: neem paste on open blisters, turmeric, ash, oils, or antiseptic powders. Neem leaves in a cool bath are a harmless tradition; pastes on broken skin are how infections start.

Antiviral medicine is used in specific situations — older children, teenagers, adults, and anyone with a weak immune system or a skin condition — and only if started early. That is a doctor's decision.

The vaccine, and who is at risk

The varicella vaccine is on most private schedules in India, usually the first dose after twelve months and a second dose later. It is not in the national programme, so many Indian children are unvaccinated.

It considerably reduces the chance of getting chickenpox, and in vaccinated children who do get it, the illness is usually much milder.

Higher-risk groups where chickenpox is more dangerous: newborns, pregnant women who are not immune, teenagers and adults, and anyone with a weakened immune system or on steroids. If a pregnant woman who has never had chickenpox is exposed, she should contact her doctor promptly — treatment exists and timing matters.

When to see a doctor

Emergency: difficulty breathing, a stiff neck, severe headache, confusion or drowsiness, a fit, unsteadiness on the feet, or a blister area that becomes very red, hot, swollen and painful with spreading redness. Call 108 for breathing trouble.

Same-day: any chickenpox in a baby under three months or in a child with a chronic illness or on steroids; fever that returns after settling or lasts beyond four days; blisters that look infected or ooze pus; a child who will not drink; severe abdominal pain; or spots in the eye.

Frequently asked questions

Q: How long should my child stay home? — Until every blister has crusted over, usually about a week from the rash appearing. Schools will ask, and it protects the other children.

Q: Can a child get chickenpox twice? — Rarely, and it happens. The virus also stays dormant and can reappear decades later as shingles, which is a different illness.

Q: Will the spots scar? — Most fade completely. The ones that scar are the ones that were scratched or became infected — which is why nails, mittens and itch relief matter more than any cream.

Q: Should I deliberately expose my other child to get it over with? — No. Chickenpox parties are a bad idea: the illness can be severe, the timing cannot be controlled, and the vaccine achieves the same protection safely.
