Step-by-step explanation:
Sexually transmitted infections (STIs) or sexually transmitted diseases (STDs) pose risks such as pregnancy, the transmission of diseases, and impacts on emotional health.
For instance, if STIs go untreated, they can lead to serious diseases like pelvic inflammatory disease (PID), which can cause infertility or ectopic pregnancy. Some STIs can also lead to long-term health issues like syphilis, which can invade internal organs and cause death.
Prevention methods include practicing safe sex behaviors, such as using condoms, getting vaccinated (e.g., HPV vaccine), and avoiding sexual contact.
