What are STDs?

Sexually transmitted diseases (STDs) are passed from one person to another through intimate physical contact – such as heavy petting –  and from sexual activity including vaginal, oral, and anal sex. STDs are very common. In fact, CDC estimates 20 million new infections occur every year in the United States. STDs can mostly be prevented by not having sex. If you do have sex, you can lower your risk by using condoms and being in a sexual relationship with a partner who does not have an STD. STDs do not always cause symptoms, so it is possible to have an infection and not know it. That is why it is important to get tested if you are having sex. If you are diagnosed with an STD, know that all can be treated with medicine and some can be cured entirely.

There are dozens of STDs. Some STDs, such as syphilis, gonorrhea, and chlamydia, are spread mainly by sexual contact. Other diseases, including Zika and Ebola, can be spread sexually but are more often spread through ways other than sex.
