Pubic lice and scabies and contagious molluscum contagiosum are different from sexually transmitted diseases. They are rarely spread through non-sexual contact. The vast majority are spread through unclean sexual contact, but they can also be transmitted indirectly through items such as underwear, mattresses, and toilet seats. The skin damage caused by pubic lice is mainly due to the irritation from their mouthparts during blood-sucking and the chemical irritation from their saliva, which leads to dermatitis and itching in the pubic hair area. When pubic lice bite the skin and suck blood, their toxic saliva enters the bloodstream, which can cause hemoglobin to change in the body, often resulting in purple or bluish patches at the bite site. Scratching the skin can also lead to conditions such as folliculitis and secondary skin infections. Additionally, pubic lice can occasionally spread diseases such as typhus and relapsing fever.
