The occurrence of lice is termed pediculosis, commonly referred to as a lice infestation. Effective treatment is required to eradicate the parasites.
When lice appear, what is it called? - in detail
The emergence of lice on a human host is medically termed «pediculosis». This condition is classified according to the species involved: head lice (Pediculus humanus capitis), body lice (Pediculus humanus corporis), and pubic lice (Pthirus pubis). Each type exhibits distinct biological traits and transmission pathways.
Symptoms arise from the insects’ feeding activity and the host’s allergic reaction to saliva. Common manifestations include:
- Itching localized to the scalp, torso, or genital area
- Presence of live lice or nits attached to hair shafts
- Red papules or secondary skin lesions caused by scratching
Transmission occurs through direct head-to-head contact for head lice, contaminated clothing or bedding for body lice, and sexual contact for pubic lice. Infestations spread rapidly in crowded or unhygienic environments.
Effective management combines mechanical removal and pharmacological treatment. Recommended steps:
- Use a fine-toothed comb to extract lice and nits from damp hair; repeat every 2–3 days for two weeks.
- Apply a topical pediculicide containing permethrin (1 %) or dimethicone, following label instructions precisely.
- Wash clothing, bedding, and personal items in hot water (≥ 60 °C) or seal them in plastic bags for 48 hours to eliminate dormant stages.
- Re‑examine all close contacts; treat any additional cases simultaneously to prevent reinfestation.
Prevention focuses on minimizing opportunities for lice transfer. Practices include avoiding the sharing of hats, combs, or towels, maintaining regular hair hygiene, and conducting routine inspections in settings where close contact is common, such as schools or group living facilities.
