¿Cómo funcionan las ITS y las ETS?

STIs (sexually transmitted infections) or STDs (sexually transmitted diseases) are contagious illnesses spread through sexual contact. They are caused by various microorganisms including bacteria, viruses, fungi, and parasites found in bodily fluids such as saliva, blood, semen, and vaginal fluids. Common examples include chlamydia, gonorrhea, syphilis, herpes, and HIV/AIDS. These pathogens can be transmitted through unprotected sexual activity, leading to infection and the potential development of symptoms or complications. Regular testing, practicing safe sex, and seeking timely treatment are essential for preventing the spread of STIs and maintaining sexual health.
