What Are STDs?

Sexually transmitted diseases (STDs), also known as sexually transmitted infections (STIs), are very common. Millions of new infections occur every year in the United States.

STDs 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 very common.


STD or STI? 

A sexually transmitted infection (STI) is a virus, bacteria, fungus, or parasite people can get through sexual contact. Many STIs have no symptoms, so people can have an infection but not know it. A sexually transmitted disease (STD) develops because of an STI and the term implies that the infection has led to some symptom of disease. People sometimes use the terms in one another’s place. 


 

What if my partner or I have an incurable STD?

Some STDs, like herpes and HIV, aren’t curable, but a doctor can prescribe medicine to treat the symptoms.

If you are living with an STD, it’s important to tell your partner before you have sex. Although it may be uncomfortable to talk about your STD, open and honest conversation can help your partner make informed decisions to protect his or her health.
