Parasitic Infections

These STIs are caused by parasites passed from person-to-person during sexual activity. A parasite is a creature that lives off another being’s body. Think of a parasite as a little bug that lives off a human but cannot always be seen by the naked eye.

  • Trichomoniasis (Trich): This single-celled organism can infect the urethra, bladder, vagina, cervix or get under the foreskin.  It can be transmitted through sexual activity and by sharing sex toys.
  • Pubic Lice (Crabs): Pubic lice are also called crabs, because that’s what they look like under a microscope. Public Lice live in pubic hairs around the genitals. They lay eggs at the base of the hair.
  • Scabies (Mites): Scabies are tiny mites that dig little holes below the surface of the skin where they lay eggs.
