Infestation with lice is medically termed as?

The term for infestation with lice is "pediculosis." This word specifically refers to the condition caused by parasitic lice living on or in the human body. There are different types of pediculosis, such as pediculosis capitis (head lice), pediculosis corporis (body lice), and pediculosis pubis (pubic lice). Each type is associated with its specific site of infestation and can present with symptoms such as itching or irritation.

The other options provided are related to skin conditions but do not pertain to lice infestations. Dermatitis refers to inflammation of the skin, eczema is a type of dermatitis often characterized by itchy and inflamed skin, and psoriasis is a chronic autoimmune condition that leads to the rapid growth of skin cells resulting in thick, red, scaly patches. These terms are distinct from pediculosis, which is specifically about lice infestation.
