How Are Sexually Transmitted Infections (STIs) Contracted?

In today’s society, many men and women suffer from sexually transmitted infections (STIs). Due to the stigma and embarrassment often associated with STIs, most individuals choose not to seek treatment. So, how are STIs contracted?

How Are STIs Contracted?

STIs are primarily transmitted through the following routes: Sexual contact—especially unprotected sexual contact—is the main route of STI transmission and the primary driver behind the widespread prevalence of STIs in contemporary society. Iatrogenic infection occurs via blood transfusions or blood products, contaminated medical instruments, artificial insemination, or organ transplantation. With increasingly stringent screening and disinfection protocols—and implementation of the “one needle, one syringe” policy—the risk of iatrogenic transmission is steadily declining.

Mother-to-child (vertical) transmission: An infected mother may transmit an STI to her newborn during vaginal delivery or through close contact—including breastfeeding—with the infected infant. Indirect transmission: Infection may occur when pathogens present in blood, vaginal secretions, or semen come into contact with broken skin or mucous membranes. There is also a very low risk of transmission through brief shared use of items such as bath towels, swimsuits, or swim trunks. While not impossible, such transmission is exceedingly rare. Therefore, there is no need for excessive fear or avoidance of discussing STIs! Everyday activities—including staying in hotels or swimming—generally pose negligible risk of STI transmission.

Patients should maintain good personal hygiene in daily life—washing the genital area daily with warm water—and avoid unhygienic sexual practices. Having a consistent, mutually monogamous sexual partner is strongly recommended. We hope this information proves helpful to you!
