There are three main types of lice ectoparasites:
1. Head lice (Pediculus humanus capitis): These are small, wingless insects that infest the scalp and hair. They feed on human blood and lay their eggs (nits) on the hair shafts close to the scalp. Head lice are most commonly found in children and can spread through close personal contact or sharing personal items like combs, hats, or headphones.
2. Body lice (Pediculus humanus corporis): Body lice are similar to head lice but infest clothing and bedding rather than the scalp. They only move to the body to feed on human blood. Body lice are usually associated with poor hygiene and crowded living conditions. They can transmit diseases like typhus, trench fever, and louse-borne relapsing fever.
3. Pubic lice (Pthirus pubis): Also known as "crabs," pubic lice infest the pubic hair and genital area. They are usually transmitted through sexual contact but can also spread through close personal contact or sharing infested bedding or clothing. Pubic lice feed on human blood and can cause intense itching and irritation.
It is important to note that while these three types of lice infest different areas of the body, they are all ectoparasites that rely on human blood for survival and reproduction.
