What is an STI?

"What is an STI" page header

Sexually transmitted infections (STIs), also known as sexually transmitted diseases (STDs), are very common. Millions of new infections occur every year in the United States.
 
STIs pass from one person to another through vaginal, oral, and anal sex. They also can spread through intimate physical contact like heavy petting, though this is not as common.
 
STIs can be asymptomatic or just cause mild symptoms. It is possible to have an infection and not know it.
 
Getting tested is important if you are having sex and infections are easy to miss if you don’t get tested.
 
If you get a STI, all are treatable with medicine, and many are curable entirely.

 

If either you or your partner is infected, both of you need to receive evaluation and treatment at the same time to avoid getting re-infected.
