Quick Answer
Yes, you can spread certain STIs to other parts of your own body — mostly herpes (touching a sore then your eye or mouth) and molluscum contagiosum (scratching bumps spreads them). Thorough handwashing after touching affected areas prevents this.
- Herpes: touching a cold sore then your eye can cause herpetic keratitis — a serious eye infection.
- Molluscum: scratching bumps spreads the virus to surrounding skin in a line pattern.
- HPV: self-inoculation to different genital sites is possible but uncommon.
- Scabies: scratching spreads mites to new body areas.

Self-inoculation requires live virus transfer from one site to another via hands or contact. Handwashing between touching affected and unaffected areas is the single most effective prevention.
