Clinical information about STD exposure

When medical professionals refer to STD exposure, they're not referring to having an STD. It's meant to say that a patient has been in contact with a person with a sexually transmitted disease, and the patient might have been exposed to whatever STD that person has.

A person can gain an STD through sexual activities, whether sexual intercourse, anal sex, oral sex, and exchanging bodily fluids. If the STD is herpes, it can spread through skin-to-skin contact between sex partners.

People need to be aware of their sex partner's sexual health history so they can make informed decisions about whether or not they should sleep with them. Knowing a sex partner's sexual health history can prevent a person from putting themself at risk of being infected with an STD.
