Which option correctly identifies a prevention strategy listed for STIs?

• A. Condoms
• B. Vaccinations
• C. Screenings/testing
• D. Antibiotics after exposure only

Answer: (C)

Screening and testing for STIs is a prevention approach because it catches infections early, often before symptoms appear. Many STIs can be asymptomatic for a long time, so people might unknowingly transmit them. Regular screening allows prompt diagnosis and treatment, which shortens how long someone is infectious and reduces the chance of passing the infection to partners. It also supports public health goals by identifying cases in a community and enabling timely partner notification and re-testing when needed. While other strategies like condoms and vaccines are important and do reduce risk, screening/testing directly targets detecting infections in the population to prevent onward transmission. Antibiotics after exposure aren’t a broad, primary prevention method for most STIs and can lead to resistance if used inappropriately, and vaccines protect only certain infections rather than all STIs.
