Which of the following is a key preventive measure for reducing sexually transmitted infection transmission in sexually active individuals?

• A. Regular condom use
• B. Abandoning sex altogether
• C. Relying on antibiotics after exposure
• D. Vaccination only for HPV

Answer: (A)

Regular condom use works by creating a barrier that blocks the exchange of infectious organisms during sex and limits skin-to-skin contact in the areas covered. When used consistently and correctly, condoms significantly lower the risk of transmitting many sexually transmitted infections, including HIV, chlamydia, gonorrhea, and syphilis. They are most effective when used from the start of intercourse and continued through the end, with proper storage, checks for expiration, and the use of appropriate lubricants to prevent breakage. While not perfect—some infections can be transmitted through areas not covered by a condom or during non-penetrative sex—they remain one of the most practical and broadly protective measures for sexually active people. Other options aren’t as effective for broad prevention: abstaining from sex eliminates risk but isn’t a realistic approach for most individuals; relying on antibiotics after exposure treats infections but isn’t preventive and can contribute to antibiotic resistance; vaccination for HPV reduces risk for that specific infection but doesn’t prevent other STIs. Regular condom use stands out as the most effective general preventive strategy.
