Which of the following is a comprehensive set of prevention approaches for STIs?

• A. Condoms, vaccinations, screenings/testing, PrEP/PEP, monogamy, education
• B. Condoms only
• C. Vaccinations only
• D. Screenings/testing only

Answer: (D)

A comprehensive set of STI prevention combines behavioral, biomedical, and health-services strategies to reduce risk, prevent infection, and catch infections early. Condoms provide barrier protection during sex, lowering the chance of transmitting many STIs. Vaccinations protect against infections like HPV and hepatitis B, which have effective vaccines. Regular screenings and testing help detect infections early, allowing timely treatment and reducing onward transmission, especially for infections that can be asymptomatic. PrEP and PEP offer HIV-specific prevention benefits when used correctly, providing additional protection beyond barrier methods. Relationship factors, such as mutually monogamous partners who are uninfected, can also reduce risk, and education supports people in understanding and applying these options. Together, these pieces create a truly comprehensive approach; focusing only on screenings/testing leaves out key preventive measures like condoms, vaccines, and prophylaxis that prevent infection in the first place.
