WHAT IS AN STI?

An “STI” — which stands for “Sexually Transmitted Infection” — is an infection that passes from one person to another through vaginal, oral, and anal sex. STIs can also spread through intimate physical contact like heavy petting, though this is not very common, and through non-sexual contact (for example, people who share needles can infect each other with HIV).

STIs are very common, with millions of new infections occurring every year in the United States.

STIs don't always cause symptoms or may cause only mild symptoms. Therefore, it is possible to have an infection and not know it. If you are sexually active, it’s important that you get tested.

Please note: We use the term “STI” instead of long-used term “STD” (which stands for “Sexually Transmitted Disease”). “STI” is the most up-to-date term — educators and health care providers switched from STD to STI because “infection” is more accurate and less stigmatizing than “disease.” Still, both terms may be used somewhat interchangeably by health providers and health care organizations.

Which Tests Should I Get? (CDC website)

If you receive a positive diagnosis, know that all are treatable with medicine and some are curable entirely.

STIs are preventable. If you have sex, know how to protect yourself and your sex partner(s) from an STI.
