Get StartedRisk factors
By Mayo Clinic staffYou face an increased risk of acquiring syphilis if you:
- Engage in high-risk sexual activity, including unprotected sex, sex with multiple partners, having sex with a new partner, or having sex under the influence of drugs or alcohol
- Are a man who has sex with men
- Are infected with the human immunodeficiency virus (HIV)
The more sexual partners you have, the more likely you are to get syphilis or another sexually transmitted disease (STD). Even if you've had syphilis and been treated for it previously, you can get it again.
