Sexually transmitted diseases (STDs) are infections that are passed from one person to another through sexual contact.
The causes of STDs are bacteria, parasites, yeast, and viruses.
Sexually transmitted diseases (STDs) are passed from one person to another through intimate physical contact – such as heavy petting – and from sexual activity including vaginal, oral, and anal sex. In fact, CDC estimates 20 million new infections occur every year in the United States. If you do have sex, you can lower your risk by using condoms and being in a sexual relationship with a partner who does not have an STD.
STDs do not always cause symptoms, so it is possible to have an infection and not know it.
Pr EP involves taking one pill (an HIV medicine called Truvada) daily to prevent HIV infection.
