Which steps reduce the risk of contracting an STI?

Correct answers — all that apply:

• using condoms correctly and consistently
• avoiding certain types of sexual contact but not others
• practicing abstinence
• getting vaccinations before becoming sexually active

Notes:

• "Stopping casual contact with others" is ambiguous and generally not listed as a standard STI-prevention measure unless it means reducing number of sexual partners; casual nonsexual contact (e.g., hugging, shaking hands) does not transmit STIs.
• Vaccinations relevant include HPV and hepatitis B. For personalized advice, consult a healthcare provider.
