Facts about STDs
The term sexually transmitted disease (STD) is used to refer to a condition passed from one person to another through sexual contact. A person can contract an STD by having unprotected vaginal, anal, or oral sex with someone who has the STD.
An STD may also be called a sexually transmitted infection (STI) or venereal disease (VD).
That doesn’t mean sex is the only way STDs are transmitted. Depending on the specific STD, infections may also be transmitted through sharing needles and breastfeeding.
