Sexually Transmitted Infections (STIs) and Related Conditions

Below is a list of sexually transmitted infections (STIs) and other conditions associated with STIs. Some of these conditions are not sexually transmitted but may increase in frequency with sexual activity.  Some are conditions caused by STIs.

Why "STI" (sexually transmitted infections) and not "STD" (sexually transmitted disease)?

The terms STI and STD are synonymous. "STI" is used more frequently now because of the negative association with the term "disease" and because some diseases are considered incurable. In contrast, there is usually less stigma attached to the term "infection" and many STIs are actually easily curable.
