Three forms of pediculosis affect the human host, each with a predilection for certain parts of the body.
Pediculosis capitis. or head lice, is the most common type and is seen primarily in preschool and school-age children, especially girls. Transmission occurs by coming into direct contact with lice or by sharing infested brushes, combs, and hats. Adult lice and their eggs (nits) are found principally in the occipital region and behind the ears. Symptoms include severe itching, often resulting in excoriation and secondary bacterial infection.
Pediculosis pubis is seen most commonly in sexually active adolescents and young adults, although occasionally it may be found on the eyelashes of small children who come in contact with infected individuals.
