Sexually Transmitted Diseases (STDs): Overview. Sexually transmitted diseases (STDs), also known as sexually transmitted infections (STIs), are typically caused by bacteria or viruses and passed from person to person during sexual contact with the penis, vagina, rectum, or mouth.
Sexually transmitted diseases (STDs) are diseases that are mainly passed from one person to another during sex. There are at least 25 different sexually transmitted diseases with a range of different symptoms. These diseases may be spread through vaginal, anal and oral sex.ost sexually transmitted diseases will only affect you if you have sexual contact with someone who has an STD. However there are some infections, for example scabies, which are referred to as STDs because they are most commonly transmitted sexually, but which can also be passed on in other ways.
