Head lice are parasites that can be found on the heads of people. Infection with head lice is called pediculosis. (The head louse, Pediculus humanus capitis, is different from the lice that cause body and pubic-hair infections.)
In this manner, what causes head lice to begin?
Head lice infestation, also known as pediculosis capitis and nits, is the infection of the head hair and scalp by the head louse (Pediculus humanus capitis). The cause of head lice infestations are not related to cleanliness. Other animals, such as cats and dogs, do not play a role in transmission.
Where does head lice come from in the first place?
The clades of human head lice, named A, B, and C, have different geographic distribution and varying genetic characteristics. According to the Journal of Parasitology, Clade B head lice originated in North America, but migrated to farther reaches of the world, including Australia and Europe.
How Lice are spread?
Head lice move by crawling; they cannot hop or fly. Anyone who comes in head-to-head contact with someone who already has head lice is at greatest risk. Spread by contact with clothing (such as hats, scarves, coats) or other personal items (such as combs, brushes, or towels) used by an infested person is uncommon.
