Is chickenpox safe in children?

Chickenpox is a viral infection that commonly causes an itchy rash, fever, tiredness and fluid-filled spots that appear in crops. The spots can crust as they heal. Scratching can break the skin and allow bacterial infection, while some children become more unwell with dehydration, breathing problems or nervous-system symptoms. Risk is greater for infants, children with weakened immunity and those taking certain medicines. A child can spread the virus before every spot has crusted, so close contact with pregnant people, newborns and people with reduced immunity should be avoided.

Offer frequent fluids, keep fingernails short and use the clinician-approved method for easing itch. Dress the child in loose clothing and avoid overheating. Keep the child home from school or childcare while they are infectious, following local health advice. Do not give aspirin to a child with suspected chickenpox. Check with a clinician before giving ibuprofen or any new medicine, especially if the child has another illness. Call early for advice if the child is very young, immunocompromised or has had close contact with someone vulnerable.

Seek medical advice for fever that persists or returns, worsening redness around spots, pus, severe headache, unusual sleepiness, repeated vomiting, difficulty walking, breathing trouble, poor drinking or reduced urination. Get urgent help if the child is difficult to wake, has a seizure, struggles to breathe or develops a rapidly worsening condition. Phone ahead before visiting a clinic so other patients can be protected from exposure.

Ask whether the rash fits chickenpox, which itch and fever medicines are suitable for your child's age, how to protect household contacts, and when the child may return to school. Mention immune problems, regular medicines and any exposure to a pregnant person or newborn.
