This is the most important question. The answer is: Laser removes the visible wart (the symptom), but it does NOT remove the HPV virus from your body. The virus lives in the basal layer of the skin around the wart. Even after the wart is gone, you may still have viral particles in the 'clinically normal' skin surrounding the area. This means you can still spread the virus to other parts of your body (autoinoculation) or to other people via skin-to-skin contact. However, once the wart is removed, your immune system often 'wakes up' and clears the virus over time (months to a year). To reduce spread: Do not touch the area and then touch other body parts. Wash your hands obsessively. Do not share towels, razors, or shoes. Use a separate nail clipper for that foot. The good news: If the wart doesn't come back for 6-12 months, your immune system has likely suppressed the virus.
