Impetigo in Children: Honey-Crust Sores and Rainy Season Care
Golden-brown crusts around a child’s nose and mouth, on skin that was scratched or bitten a few days ago, are the classic look of impetigo. It is a bacterial skin infection that spreads fast in wet, crowded weather, and it needs a doctor or pharmacist to decide the treatment, not a home paste.
The short version
- What it looks like: red sores or blisters that burst and leave honey-coloured or golden-brown crusts, often near the nose, mouth and hands.
- Who decides care: a doctor or pharmacist. The right cream or medicine is their call.
- How contagious: very. Per the NHS, it stops being contagious 48 hours after treatment starts, or once sores have dried and crusted over if left untreated.
- School: keep the child home until then.
- Best home habit: short nails, loose cover on sores, own towel, frequent hand washing.

What does impetigo look like in a child?
It starts small. A red spot, or a tiny blister, usually where the skin was already broken: a scratched mosquito bite, a graze from the playground, a bit of eczema, a runny nose that chapped the upper lip. The blisters burst quickly. What is left is a crust the colour of dried honey or toffee, sometimes described as looking like cornflakes stuck on the skin.
The common spots are around the nose and mouth, and on the hands. The sores can itch or sting. On brown and black skin the redness is harder to see, so look at the crust and the weeping rather than waiting for obvious redness.
There is a second type with larger fluid-filled blisters that ooze yellow fluid and then harden into a scab with a scaly edge. It is more common in babies and young children. Both types are handled the same way: see someone who can examine the skin.
Why does it show up after rain and floods?
Three things stack up. Mosquitoes and other insects bite more, and children scratch the bites. Skin stays damp, whether from wet clothes, wet feet or sweat that cannot dry, and damp skin breaks down more easily. And people are close together, in crowded homes, shared beds or relief camps, so the bacteria hop from child to child on hands, towels and toys.
None of this means the child was dirty. A clean child with a scratched bite can get it. For camp conditions more broadly, see flood relief camp diarrhoea and skin rashes, and for the baby angle, rainy season rashes in babies.
Is it impetigo, ringworm or scabies?
Parents often mix these up, and it is fair to. Here is a rough guide, not a diagnosis.
| Clue | Impetigo | Ringworm | Scabies |
|---|---|---|---|
| Look | Honey crusts, weeping sores | Ring with a clearer centre, scaly edge | Tiny bumps, burrow lines, scratch marks |
| Where | Nose, mouth, hands | Body, scalp, groin | Finger webs, wrists, waist |
| Itch | Mild to sore | Variable | Intense, worse at night |
Scalp patches with broken hair are a different story, covered in scalp ringworm in children. Night-time itching across the whole household points to scabies. If you cannot tell, the answer is the same: let a clinician look.
Why can’t I just apply something from home?
Impetigo is caused by bacteria, and which cream or medicine fits depends on how widespread the sores are and the child’s age. That decision belongs to a doctor or pharmacist. Turmeric paste, toothpaste, ghee or leftover creams from another rash can irritate the sores or hide how they are changing. Do not give or change any medicine on your own, and if the doctor prescribes one, follow the pack and their instructions exactly, including finishing the course.
What you can do right away is gentle cleaning: wash the sore area with soap and water, pat it dry with a paper towel or a cloth only that child uses, and wash your hands before and after.
The nail and cover trick
Trim the child’s nails short and smooth, then cover sores loosely with a clean, dry dressing or gauze. Scratching is how one patch becomes five. Change the cover when it is damp or dirty, and wash your hands after. A loose cover also stops small fingers picking at the crusts, which can leave marks.
How do I stop it spreading in the family?
- Give the child their own towel, flannel and pillowcase. Nobody else uses them.
- Wash towels, sheets, pillowcases and the child’s clothes at the hottest setting the fabric allows, and dry them fully in sun or a dryer.
- Wash toys the child mouths or holds with detergent and warm water.
- Everyone washes hands with soap after touching the sores or the dressings.
- Keep the child away from newborns, anyone with diabetes, and anyone with a weak immune system until the sores have healed or treatment has run its first two days.
- Do not prepare food for others while you have sores on your own hands.
When can my child go back to school?
The NHS marker is 48 hours after treatment begins. If the sores are untreated, the child can stay contagious for a week to three weeks, roughly until the patches have dried out and crusted over. Many schools and nurseries have their own exclusion rule, so call and ask. A note from the doctor or pharmacist that treatment has started helps.
The child is under 12 months, the sores are spreading quickly, there is fever, the child seems unwell or very sleepy, the skin around the sores turns hot, swollen or red and streaky, the sores do not improve after a couple of days of treatment, or impetigo comes back within a year. Sores near the eyes also need prompt attention. Dark or cola-coloured urine, puffy eyes or face in the weeks after a skin infection is also a reason to see a doctor the same day. In an emergency, call your local emergency number (1122 in Pakistan, 112 in India).
What makes it worse?
Picking crusts. Sharing towels. Putting a damp bandage on and leaving it for a day. Sending the child back to school too early. Scrubbing hard, which breaks more skin. And ignoring the original bite or graze: wash small cuts with clean water and keep them dry, especially in the rainy season, when floodwater and mud get onto skin.
Common questions about impetigo in children
What is impetigo?
Impetigo is a contagious bacterial skin infection that causes sores and honey-coloured crusts, usually on the face and hands. It is common in children and often follows a scratch, bite or other break in the skin.
Why is it called honey coloured crust in children?
Because the fluid from the burst blisters dries into a golden-yellow to brown crust that looks like dried honey. That crust, sitting on a red, weeping base, is the feature doctors look for.
Is impetigo contagious in school?
Yes, very. It spreads by touch and by shared towels, bedding and toys. The NHS says it stops being contagious 48 hours after treatment starts, so the child stays home until then.
How is impetigo different from ringworm?
Impetigo makes weeping sores with honey crusts, while ringworm forms a scaly ring that spreads outward and often has a clearer centre. Neither can be told reliably by eye at home, so have a clinician check any spreading patch.
What causes sores around a child’s mouth?
Several things can, including impetigo, cold sores, lip licking, drooling and eczema. Honey-coloured crusts that spread or weep suggest impetigo. Painful clusters of small blisters point more to a cold sore. A clinician can tell them apart.
How long does impetigo last?
With treatment it often improves within a few days. Untreated, it can take a week to three weeks to dry out and stop being contagious. Mild cases can fade without treatment, but seeing a doctor shortens the time it can spread.
What is the right home care for impetigo?
Wash the area gently with soap and water, pat dry, keep nails short, cover sores loosely and give the child their own towel. The treatment itself, whether a cream or a medicine, should be chosen by a doctor or pharmacist.
Can impetigo start after an insect bite?
Yes. Scratching a mosquito or other insect bite breaks the skin and lets bacteria in. That is why it is so common in the rains. Keeping nails short and bites clean and dry lowers the chance.
Can adults catch impetigo from a child?
Yes, especially through cuts or broken skin on the hands. Wash hands after touching the child’s sores, do not share towels, and see a doctor if you develop similar sores.
Should I pop the blisters or remove the crusts?
No. Picking can spread the infection and leave marks. Gentle washing with soap and water loosens crusts naturally, and the doctor’s treatment does the rest.
