Pediculosis is an infestation caused by head lice, i.e. tiny wingless insects whose spread and transmission has little to do with the cleanliness of the environment or the individual who contracts it.
In fact, transmission occurs mainly in crowded environments through direct contact between people, or through the shared use of objects such as combs, brushes or hats.
Head lice occur most commonly in pre-school children but can also affect adults. Infestation is manifested by irritation and intense itching in the infected area.
