Sexually Transmitted Infections (STIs)

The information provided here is intended to answer some of the most commonly asked questions about STIs. It does not replace your need to talk to a health care provider if you believe you have been exposed to, or are at risk of exposure to, an STI.

What are STIs?

STIs are infections passed from person to person by sexual contact. STIs are one part of a broader group of infections known as reproductive tract infections (RTIs). The following diseases can be transmitted by sexual contact:

Chlamydia
Gonorrhea
HIV Infection/AIDS
Hepatitis B
Hepatitis C
Herpes
Human Papillomavirus (genital warts)
Pelvic Inflammatory Disease
Syphilis
Trichomoniasis

These infections may lead to symptoms in the reproductive organs themselves as well as the skin around the vagina, penis, or anus. Some STIs also cause systemic symptoms that cause problems in other parts of the body.

Some STIs (for example chlamydia, gonorrhea, human papilloma virus (HPV), hepatitis B, and genital herpes) often cause no symptoms. Therefore, although the person has an infection, he or she may have no symptoms and may not realize that he or she is infected. STIs without symptoms can be transmitted to others and can cause serious complications.

These infections may lead to serious complications, especially if they are not treated. In addition, STIs increase the risk of acquiring or transmitting HIV, the virus that causes AIDS. For your comfort and safety, as well as that of your sex partners, all STIs should be treated promptly.

If you believe you might have an STI, you should be evaluated by a health care provider as soon as possible.
