A schoolchild has lice; what should be done? - briefly
Treat the child with a recommended lice shampoo, comb the hair with a fine-toothed nit comb, and launder clothing and bedding in hot water or seal them for two weeks. Notify classmates and school staff so they can inspect and, if needed, apply preventive treatment.
A schoolchild has lice; what should be done? - in detail
A child has been found to carry head‑lice. The first action is to confirm the infestation by examining the scalp and hair for live insects or viable eggs (nits) within 1 cm of the hair shaft. Once confirmed, inform the parents or guardians immediately and advise that treatment should begin without delay.
Treatment options
- Over‑the‑counter pediculicides – shampoos or lotions containing 1 % permethrin or 0.5 % pyrethrins with piperonyl butoxide. Apply according to the product label, leave for the specified time, then rinse and repeat after 7–10 days to eliminate newly hatched nymphs.
- Prescription medications – 0.5 % malathion, 0.1 % ivermectin, or oral ivermectin for resistant cases. Use under medical supervision.
- Mechanical removal – fine‑toothed nit comb on wet, conditioned hair. Perform combing every 2–3 days for two weeks, removing all visible nits.
Environmental decontamination
- Wash bedding, hats, scarves, and clothing in hot water (≥ 60 °C) and tumble‑dry on high heat.
- Seal items that cannot be washed in a sealed plastic bag for at least 48 hours.
- Vacuum carpets, upholstery, and car seats; discard vacuum bags promptly.
- Do not spray insecticides in the home; they are ineffective against lice.
Preventive measures
- Instruct the child to avoid head‑to‑head contact during play and sports.
- Prohibit sharing of combs, brushes, hats, hair accessories, or headphones.
- Conduct weekly scalp checks for all students, especially after known outbreaks.
- Educate staff and families about the life cycle of lice and the importance of completing the full treatment regimen.
School protocol
- Notify the school nurse or designated health officer, who should record the case and inform other parents while maintaining confidentiality.
- Follow the institution’s policy regarding exclusion: typically, the child may return after the first treatment has been applied and a follow‑up inspection confirms no live lice.
- Provide written instructions to parents outlining treatment steps, environmental cleaning, and monitoring procedures.
By adhering to these steps, the infestation can be eradicated promptly, minimizing spread and reducing the likelihood of recurrence.
