Participants may have study visits as an outpatient or an inpatient (admitted overnight to the NIH hospital) and be followed over several years by our doctors and researchers at the NIH. Participants may have a cervical and/or anal Pap test. They may give samples of semen, cervicovaginal secretions, urine, saliva, or stool. Small pieces of skin, the inside of the cheek, and/or the gums may be collected with a punch or scrape biopsy to understand how HPV affect the growth of cells. Mucus and skin may be collected by rubbing the area with a cotton swab. Collection areas may include the inside the mouth, nostrils, skin, genitals, and/or in or around the anus. Biopsies may be collected. If participants need to have …
