Rashes in children: when to call an ambulance at once (the glass test), the most common causes, mistakes parents make and when to see a paediatric dermatologist. Fergana and Kokand.

Key takeaways

  • A rash that does not fade when pressed, plus fever — call 103 at once
  • Most childhood rashes are harmless: atopic dermatitis, heat rash, nappy rash, allergy
  • Do not use adult or steroid creams on a child on your own
  • A rash that lasts 2–3 days or spreads needs a dermatologist
  • Take a photo of the rash before the visit

Rashes are very common in children and often worry parents. Most are harmless and clear quickly, but some need a doctor's examination and, rarely, urgent help. This article helps you tell when to worry and when to see a dermatologist.

Call an ambulance right away (103)

Do not wait if:

  • a rash does not fade when pressed and your child has a fever. It is easy to check: press a clear glass against the rash — if the spots are still visible through the glass, call 103 at once;
  • your child is very floppy, drowsy, irritable or will not stop crying;
  • breathing becomes difficult, or the lips, face or tongue swell;
  • widespread blisters appear and the skin peels;
  • a baby under 3 months has a fever and a rash.

The most common rashes in children

  • Atopic dermatitis — dry, red, itchy skin on the cheeks and in the elbow and knee creases. More: atopic dermatitis.
  • Hives and allergy — itchy welts that come and go quickly. More: hives and skin allergy.
  • Nappy rash — redness under the nappy; frequent changes, nappy-free time and a barrier cream help. Bright redness in the folds with small spots around it may be a yeast infection.
  • Heat rash — tiny red spots on the neck, chest and back from overheating; do not over-wrap your child.
  • Viral rashes — chickenpox, rubella and other infections, often with fever. Do not pop chickenpox blisters.
  • Molluscum contagiosum — small pearly bumps with a dimple in the centre. More: molluscum contagiosum.
  • Warts — firm growths on the hands and feet. More: warts in children.
  • Scabies — night-time itching, a rash between the fingers, often in the whole family. More: scabies.
  • Fungal infection of the skin and scalp — ring-shaped patches or round patches with broken hairs, often from cats and dogs. More: fungal skin infections.
  • Cold sores — blisters around the lips. More: herpes.

What parents should not do

  • Do not use adult creams and medicines on a child.
  • Do not use steroid cream on your own — especially on the face and under the nappy.
  • Do not paint a widespread rash with iodine, brilliant green or alcohol: they burn the skin and make it harder for the doctor to see the rash.
  • Do not pop blisters or pick crusts; keep your child's nails short.
  • Before sending a child with a rash to nursery, find out whether it is contagious.

When to see a doctor

  • the rash does not clear in 2–3 days or spreads;
  • severe itching disturbs sleep;
  • the rash weeps, oozes pus or hurts;
  • other family members have a similar rash;
  • the rash is linked to a new food or medicine.

Before the visit, take a photo of the rash — some rashes fade quickly.

Paediatric dermatologist in Fergana and Kokand

At Radeski Skin Clinic a paediatric dermatologist examines the rash, performs dermoscopy and a scraping when needed, and chooses treatment and care suited to the child's age.

A child's skin is thinner and more sensitive than an adult's: show a rash to a doctor before trying to "treat" it yourself.

When to see a doctor

  • A rash that does not fade when pressed, with fever — call 103
  • The rash lasts more than 2–3 days or spreads
  • Itching disturbs sleep
  • The rash weeps, oozes pus or hurts
  • Other family members have a similar rash

Frequently asked questions

Press a clear glass firmly against the rash. An ordinary rash fades under pressure. If the spots are still visible through the glass and your child has a fever, it can be a sign of a dangerous infection — call 103 immediately.
