Sexually Transmitted Diseases (STDs)
Sexually transmitted diseases (STDs) are passed from one person to another through intimate physical contact and from sexual activity including vaginal, oral, and anal sex. STDs are very common. In fact, the Centers for Disease Control estimates 20 million new infections occur every year in the United States. STDs can mostly be prevented by not having sex.

HIV / AIDS
In the United States, HIV is mainly spread by having sex or sharing syringes and other injection equipment with someone who is infected with HIV. Substance use can contribute to these risks indirectly because alcohol and other drugs can lower people’s inhibitions and make them less likely to use condoms.
Gonorrhea is a sexually transmitted disease (STD) that can infect both men and women. It can cause infections in the genitals, rectum, and throat. It is a very common infection, especially among young people ages 15-24 years. You can get gonorrhea by having vaginal, anal, or oral sex with someone who has gonorrhea. A pregnant woman with gonorrhea can give the infection to her baby during childbirth.
Chlamydia is a common STD that can infect both men and women. Most people who have chlamydia have no symptoms. It can cause serious, permanent damage to a woman’s reproductive system. This can make it difficult or impossible for her to get pregnant later on. Chlamydia can also cause a potentially fatal ectopic pregnancy (pregnancy that occurs outside the womb). You can get chlamydia by having vaginal, anal, or oral sex with someone who has chlamydia.
HPV is transmitted through intimate skin-to-skin contact. You can get HPV by having vaginal, anal, or oral sex with someone who has the virus. It is most commonly spread during vaginal or anal sex. HPV is a group of more than 150 related viruses. Each HPV virus in this large group is given a number which is called its HPV type. HPV is named for the warts (papillomas) some HPV types can cause.
Correctly using male condoms and other barriers like female condoms and dental dams, every time, can reduce (though not eliminate) the risk of sexually transmitted diseases (STDs), including human immunodeficiency virus (HIV) and viral hepatitis.
Syphilis is a sexually transmitted infection that can cause serious health problems if it is not treated. Syphilis is divided into stages (primary, secondary, latent, and tertiary). There are different signs and symptoms associated with each stage. You can get syphilis by direct contact with a syphilis sore during vaginal, anal, or oral sex. You can find sores on or around the penis, vagina, or anus, or in the rectum, on the lips, or in the mouth. Syphilis can spread from an infected mother to her unborn baby.
Genital herpes is a common STD, and most people with genital herpes infection do not know they have it. There is no cure for herpes, but medication is available to reduce symptoms and make it less likely that you will spread herpes to a sex partner.
Hepatitis B is a liver infection caused by the Hepatitis B virus (HBV). Hepatitis B is transmitted when blood, semen, or another body fluid from a person infected with the Hepatitis B virus enters the body of someone who is not infected. This can happen through sexual contact; sharing needles, syringes, or other drug-injection equipment; or from mother to baby at birth. For some people, hepatitis B is an acute, or short-term, illness but for others, it can become a long-term, chronic infection.
Pelvic inflammatory disease (PID) is an infection of a woman’s reproductive organs. It is a complication often caused by some STDs, like chlamydia and gonorrhea. Other infections that are not sexually transmitted can also cause PID. Untreated sexually transmitted diseases (STDs) can cause pelvic inflammatory disease (PID), a serious condition, in women. 1 in 8 women with a history of PID experience difficulties getting pregnant.
