This document discusses sexually transmitted infections (STIs), including common STIs such as chlamydia, gonorrhea, herpes, HIV/AIDS, and human papillomavirus. It covers how STIs are transmitted through sexual contact and from mother to baby. While some bacterial STIs can be cured with antibiotics if caught early, viral STIs like herpes and HIV/AIDS cannot be cured. Maintaining safe sex practices and getting tested regularly are important ways to prevent the spread of STIs.
