Answer

Pediculosis is very common; a report from 2000 estimates that 6-12 million Americans aged 3-11 years are infested each year. [14] No reliable data provide the exact number of annual cases among adults. Head louse infestation is more common in the warmer months, while pubic louse infestation is more common in the cooler months. [12]
