Since pediculosis is not a reportable disease, exact numbers concerning incidence are unknown. Pediculosis may be underreported because of the social stigma attached—namely, the preconceived notion that lice of any kind are related to dirt and poor personal hygiene. In fact, personal cleanliness is not a factor in head lice infestation rates. On the other hand, false-positive nit diagnosis is common. [4]
