What is an STD? A Sexually Transmitted Disease (STD), often referred to as a Sexually Transmitted Infection (STI), is any disease or infection that may be transmitted by human sexual behavior. This includes intercourse, oral sex and anal sex. Transmission of some STDâs can also occur from using an IV needle that has already been used by an infected person as well or by receiving a blood transfusion of infected blood. A mother can pass on some infections to her baby through pregnancy and while breastfeeding.
