If there are lice in a group, what should you do? - briefly
Separate individuals showing signs of infestation, treat them with an approved lice medication, and launder all bedding and clothing at ≥130 °F. Notify the group’s coordinator or health professional and perform follow‑up checks to confirm eradication.
If there are lice in a group, what should you do? - in detail
When a infestation of head lice is identified within a collective, immediate action is required to prevent further spread. The response consists of several coordinated measures.
First, confirm the presence of live insects or viable nits by inspecting affected individuals with a fine-toothed comb under adequate lighting. Document the number of cases and the severity of each.
Second, isolate the confirmed cases from the rest of the group for a minimum of 24 hours. During this period, prohibit close head-to-head contact and the sharing of personal items such as hats, brushes, or headphones.
Third, administer an approved pediculicide treatment to each affected person. Follow the product instructions precisely, including the recommended application time and the need for a second treatment 7–10 days later to eliminate newly hatched nymphs. For those who cannot use chemical agents, consider a manual removal method involving repeated combing with a fine-toothed lice comb.
Fourth, implement environmental decontamination:
- Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 60 °C) and dry on high heat.
- Seal non‑washable items in airtight plastic bags for two weeks.
- Vacuum upholstered furniture, carpets, and car seats; discard the vacuum bag or clean the canister afterward.
Fifth, educate the entire group about detection signs, transmission routes, and preventive practices. Emphasize regular head inspections and discourage sharing of personal grooming tools.
Sixth, schedule a follow‑up screening of all members one week after the initial treatment cycle. Repeat the inspection process and, if any new cases are found, restart the treatment protocol.
Finally, maintain records of each case, treatment dates, and outcomes to monitor the infestation’s trajectory and to provide evidence of compliance with health guidelines.
