STI prevention involves taking steps to reduce the risk of sexually transmitted infections. This includes using barrier methods like condoms during sexual activity, which can significantly lower the chance of transmission. Regular testing for STIs is also important, as many infections can be asymptomatic. Education about safe sex practices is crucial for prevention. Understanding the importance of mutual monogamy, limiting the number of sexual partners, and communicating openly with partners about sexual health can help reduce the spread of STIs. Vaccinations, such as those for human papillomavirus (HPV), can also provide protection against certain infections.
