How can one get lice? - in detail
Lice infestations arise through direct contact with an infested individual’s hair or scalp. The parasite cannot jump or fly; it moves only by crawling, so any situation that permits hair-to-hair contact creates a transmission risk.
Typical pathways include:
- Sharing personal items such as combs, brushes, hats, helmets, hair accessories, or headphones.
- Sleeping in the same bed, couch, or car seat as an infected person, especially when head coverings are removed.
- Participating in close‑range activities—team sports, dance classes, group camps—where heads frequently touch.
- Handling contaminated clothing, towels, or bedding that have not been washed at temperatures of at least 130 °F (54 °C) or dried on high heat.
Secondary factors increase susceptibility:
- Crowded living conditions that limit personal space.
- Poor hygiene practices that delay detection and removal of nits.
- Frequent head‑to‑head contact among children in schools or daycare centers, where infestation rates are highest.
Preventive measures focus on minimizing shared contact and maintaining regular laundering of items that may harbor lice. Early identification of live insects or attached eggs enables prompt treatment, reducing the chance of spread to others.
