Answer

Intimate or sexual contact with an individual who is infested with pubic lice is a common risk factor for pubic lice infestation. Risk factors for infestation of the pubic louse include sexual promiscuity and crowded living conditions. Contact with clothing, bedding, and towels used by an infested individual may occasionally be the cause of infestation. [14] It is a myth that pubic lice are spread by sitting on a toilet seat; pubic lice’s feet are not designed to walk on smooth surfaces such a toilet seats, and the lice cannot live for long away from a warm human body. [14]
