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 infections (STI), also referred to as sexually transmitted diseases (STD) and venereal diseases (VD), are infections that are commonly spread by sex, especially vaginal intercourse, anal sex and oral sex. Most STIs initially do not cause symptoms. This results in a greater risk of passing the disease on to others. Symptoms and signs of disease may include vaginal discharge, penile discharge, ulcers on or around the genitals, and pelvic pain.
