Lice are small parasitic insects that live on the skin. These insects are very annoying, and some are vectors of serious diseases (typhus). Head lice spreads very quickly, especially in children due to close contact and sharing personal items.
The person can parasitize three types of lice (head, body and pubic). Often lice appear on the scalp (head lice). It is easiest to see them at the nape and behind the ears. Small eggs (nits) that lice lay and attach to the hair shaft. After about a week the eggs hatch into new insects. Pediculosis is usually accompanied by severe itching.
There are many different effective ways to treat lice.
