Sexually transmitted infections (STIs) are caused by infections that are passed from one person to another during sexual contact.

These infections often do not cause any symptoms.

There are many kinds of sexually transmitted infections. And they are very common — more than half of all of us will get one at some time in our lives. Use the list above to find out about each kind of STI.

The good news is we can protect ourselves and each other from STIs. Practicing safer sex allows you to reduce your risk of getting sexually transmitted infections. And if you've done anything that puts you at risk of infection, getting tested allows you to get any treatments you may need. 

We are here to help. The caring staff at your local Planned Parenthood health center can talk with you about STIs and help you get any testing or treatment you may need.
