Sexually transmitted diseases are also called STDs (and sometimes they are referred to as sexually transmitted infections). STDs do not refer to any one disease but include more than 25 infectious organisms. STDs are caused by bacteria or viruses. STDs are almost always spread from person to person by sexual intercourse, including oral and anal sex.
