If you have had contact with infected lice, what should you do? - in detail
Exposure to lice that may be carrying pathogens requires prompt, systematic action. First, verify whether any lice or nits are present on the scalp, clothing, or personal items. Use a fine-toothed comb under bright light to detect live insects and eggs.
If infestation is confirmed, follow these steps:
- Apply an approved pediculicide according to the product label—typically a 10‑minute application followed by thorough rinsing.
- Comb out all nits with a nit comb, repeating the process every 2–3 days for two weeks to catch newly hatched lice.
- Wash all worn clothing, bedding, and towels in hot water (minimum 130 °F / 54 °C) and dry on high heat for at least 20 minutes. Items that cannot be laundered should be sealed in a plastic bag for two weeks.
- Vacuum carpets, upholstered furniture, and car seats; discard the vacuum bag or clean the canister afterward.
Seek medical evaluation if:
- The person develops a rash, fever, or unexplained skin irritation.
- Over‑the‑counter treatments fail after two applications.
- There is a known risk of disease transmission (e.g., epidemic typhus) in the region.
A healthcare professional may prescribe oral ivermectin or alternative topical agents and assess for secondary infections.
Prevent future occurrences by:
- Conducting regular head checks, especially in settings with close contact (schools, camps).
- Maintaining personal items separate; avoid sharing hats, hair accessories, or bedding.
- Educating caregivers and peers about early detection and proper treatment protocols.
These measures collectively eliminate the current problem and reduce the likelihood of re‑infestation.
