Impetigo and School: Treatment, Time Off, and Stopping the Spread

That cluster of golden, honey-crusted sores around a child's nose or mouth is unmistakable to anyone who's worked in a primary school: impetigo, one of the most contagious skin infections there is.

The good news is it's rarely serious and treats quickly — and under Pharmacy First, Lyng Pharmacy in West Bromwich can diagnose and supply NHS treatment for anyone aged 1 and over, same day, no GP appointment.

How impetigo is treated

Small, localised patches usually need an antibiotic or antiseptic cream applied for around five days; more widespread impetigo may need antibiotic tablets or liquid. Treatment matters for two reasons: it clears the infection faster, and — the part parents care about — it makes your child non-contagious much sooner, which unlocks the return to school.

The school and nursery rules

Children should stay off school or nursery until the sores have crusted over and dried out, or until 48 hours after starting antibiotic treatment — whichever comes first. Starting treatment promptly is therefore usually the fastest route back to the classroom. The same 48-hour rule applies to adults returning to work, especially in food handling and healthcare.

Stopping it spreading at home

Impetigo spreads by touch and by shared towels, flannels, bedding and toys. Give the affected child their own towel, wash bedding and clothes hot, keep fingernails short, discourage touching the sores, and wash hands relentlessly. Watch other family members for new sores for a week or so — and treat early if they appear.
