Sexually transmitted infections (STIs) usually pass from one person to another through sexual contact. Most are fairly common, and effective treatment is available — especially in the early stages.

Some STIs are benign, but others can lead to severe complications without treatment.

HIV has other routes of transmission. For example, this STI can spread through the use of unsterilized drug needles as well as sexual contact.

STIs can affect anyone, regardless of the individual’s sexual orientation or hygiene standards. Many STIs can spread through nonpenetrative sexual activity.

This article looks at some common STIs, how to prevent them, and when to seek help.
