Sexually Transmitted Diseases

Sexually transmitted diseases are also called STDs, or are referred to as sexually transmitted infections or STIs.

STDs/STIs do not refer to any one disease but include more than 25 infectious organisms.

Sexually Transmitted Diseases (STDs) are caused by bacteria or viruses.

STDs are almost always spread from person to person by sexual intercourse, but STDs can also be spread through oral sex.

Some STDs, such as hepatitis B or HIV infection, are also transmitted through blood-to-blood contact, through the sharing of needles or equipment to inject drugs, body pierce or tattoo.
