Lice have appeared again – what should be done? - briefly
Treat the infestation with an approved pediculicide, then eliminate remaining nits using a fine‑toothed comb and decontaminate personal items by washing at ≥60 °C or sealing them for two weeks. Prevent recurrence by instituting regular scalp inspections and prohibiting the sharing of hair accessories.
Lice have appeared again – what should be done? - in detail
Head lice infestations have resurfaced in many communities, creating a need for systematic response.
Detection relies on visual examination of the scalp and hair. A magnifying device or a fine-tooth comb can reveal live insects or viable eggs. Routine checks should focus on the nape, behind the ears, and the crown area.
Effective treatment comprises two parallel actions: chemical and mechanical.
- Apply an approved pediculicide according to label instructions; avoid repeated applications within the recommended interval.
- Use a nit‑comb on wet hair after treatment; comb from scalp to tip, cleaning the comb after each pass.
Environmental control reduces re‑infestation risk.
- Wash clothing, bedding, and personal items used within the previous 48 hours in water ≥ 60 °C; dry on high heat if washing at lower temperatures.
- Seal non‑washable items in sealed plastic bags for two weeks to starve surviving lice.
- Vacuum carpets and upholstered furniture; discard vacuum bags or clean canisters promptly.
Prevention focuses on early identification and education.
- Implement regular screening in schools and childcare facilities, preferably every two weeks during peak seasons.
- Inform caregivers about signs of infestation and proper use of treatment products.
- Encourage avoidance of head‑to‑head contact and refrain from sharing personal items such as hats, combs, or headphones.
