What is an STD?

STDs, or sexually transmitted diseases, are infections that are primarily spread through sexual contact. They can be caused by bacteria, viruses, or parasites, and common examples include chlamydia, gonorrhea, syphilis, and HIV. Many STDs may not show obvious symptoms, but they can have serious health consequences if left untreated. Practicing safe sex, regular testing, and open communication with partners are important ways to prevent the spread of STDs.
