What is the name of the lice infection that can infest different areas of the body?

Scabies
Pediculosis
Dermatitis
Psoriasis

The correct answer is: Pediculosis

Pediculosis is the correct term for a lice infection that can affect various areas of the body. It specifically refers to an infestation by lice, which are parasitic insects that can live on human hair and in clothing. There are different types of pediculosis depending on the area of infestation: for instance, head lice (Pediculus humanus capitis), body lice (Pediculus humanus corporis), and pubic lice (Pthirus pubis). Scabies is caused by a different type of parasite, the mite Sarcoptes scabiei, and it results in intense itching and a rash, but it is not a lice infection. Dermatitis refers to inflammation of the skin and can have various causes, including allergies or irritants, but it does not specifically pertain to lice. Psoriasis is a chronic autoimmune condition affecting the skin, characterized by the rapid growth of skin cells leading to scaling and inflammation, again not associated with lice. Thus, pediculosis is uniquely associated with the condition of lice infestation across different body areas.
