What is a recommended method to prevent sexually transmitted infections, besides abstinence?

The recommended method to prevent sexually transmitted infections, aside from abstinence, is condom use. Condoms are effective barriers that significantly reduce the risk of transmission of many sexually transmitted infections (STIs) when used consistently and correctly during sexual activity. They work by preventing direct contact with bodily fluids, which can carry pathogens responsible for STIs, including HIV, gonorrhea, chlamydia, and syphilis.

Vaccines like the one for genital warts caused by HPV are indeed useful tools in preventing certain types of infections and can help mitigate the risks associated with human papillomavirus; however, they do not prevent all sexually transmitted infections. While regular health screenings and limiting sexual partners can contribute to overall sexual health and potentially reduce the risk of STIs, they do not offer a direct preventive measure during sexual encounters. Thus, the most straightforward and effective method among the options presented is the use of condoms.
