STD stands for sexually transmitted disease. STDs are infections that can be transmitted from one person to another through sexual contact, including vaginal, anal, and oral sex. There are many different types of STDs, including HIV, gonorrhea, chlamydia, syphilis, and genital herpes.
STDs can be caused by bacteria, viruses, or parasites. Some STDs, such as HIV and syphilis, can be transmitted from an infected mother to her baby during pregnancy or childbirth. It is important to practice safe sex and to get tested regularly for STDs, especially if you have multiple sexual partners or if you are at an increased risk of infection. Many STDs can be treated with medications, but some, such as HIV, have no cure. Early diagnosis and treatment can help reduce the risk of serious complications and transmission to others.
