Causes
Body lice are primarily transmitted through direct human-to-human contact and do not involve pets. The infestation occurs when an individual with body lice shares personal items such as clothing, bedding, linens, or towels. It is important to note that people who lack access to regular bathing and changes of clothes are at a higher risk of contracting body lice.
Life Cycle
During their life cycle, adult body lice lay nearly double the number of eggs compared to head lice, with approximately 180 eggs. These eggs, which are oval-shaped and either yellow or white in color, hatch within a span of one to two weeks. Once hatched, these young lice, known as nymphs, immediately start to feed on blood, requiring a meal every five hours. Within a short period of 10 days, the nymphs fully develop into adult lice. Adult body lice are characterized by their tan or grey coloration and possess six legs, typically resembling the size of a sesame seed. When they are not on a human host, body lice have a lifespan of around five to seven days under room temperature conditions.
