What Are Lice ? Types, How they spread, Treatment, Prevention and Takeaway

2Body Lice

The body louse has the same general appearance as of head louse, but is slightly larger. Unlike the head lice, which lives and feeds on its human host, the body lice live in clothing and then transfers to the human body (host) to feed itself. The life span of the body louse and the head louse are similar in duration and character. However, a significant difference is that the body louse can survive for more than 30 days away from its human host.

Body-lice infestation is a significant health problem in largely populated communities dealing with poverty, poor personal hygiene, and overcrowding. Reused bed linens and mattresses, as well as the use of communal beds, are risk factors.

The primary symptom of a body-lice infestation is itching. Areas of the body which are tightly adherent to the clothing are the most likely to infest. Axilla, waistband lines, and bra strap regions, are the areas where excoriation (abrasion, crusts, or scabbing) from scratching is usually noted. Red and itchy bite marks may be present on the body.

The presence of body lice can be diagnosed by identifying nits or lice in clothing, linens — especially in the seamier regions or bedding.

Bed bugs are correlated to lice. They hide among blankets, sheets, and furniture and bite at night when they find a warm body for a meal. They usually leave black or brown markings on the bed linens and blankets and bite in rows, mostly leaving three or more bite marks.
