Sexually transmitted diseases (STDs) or sexually transmitted infections (STIs) are generally acquired through sexual contact. The bacteria, viruses, or parasites that cause sexually transmitted diseases can be transmitted from one person to another through blood, semen, or vaginal fluids and other body fluids. Sexually transmitted infections (STIs) are infections that can be contracted by having sex with someone who has an infection. These infections are usually transmitted from person to person through vaginal intercourse.
They can also be transmitted through anal sex, oral sex, or skin-to-skin contact. STIs can be caused by viruses or bacteria. STIs caused by viruses include hepatitis B, herpes, HIV, and human papillomavirus (HPV). STIs caused by bacteria include chlamydia, gonorrhea and syphilis.
Sexually transmitted infections (STIs), also known as sexually transmitted diseases (STDs) and the older term venereal diseases, are infections that are transmitted through sexual activity, especially vaginal intercourse, anal sex and oral sex. Some STDs are curable, while others have no cure, and if you get one of those, it can stay with you for the rest of your life. When doctors or nurses ask this question, they actually ask you if you've done anything since your last checkup that could have exposed you to an STD or pregnancy. Not 100%, but if used correctly every time, condoms are a great way to protect yourself from STDs that are transmitted through body fluids, such as semen or vaginal secretions.
STD stands for sexually transmitted disease, which is a disease transmitted through sexual behavior, such as vaginal intercourse, oral sex, anal sex, or sometimes intimate skin-to-skin contact. As mentioned above, STDs can be transmitted through oral and anal sex, but many people believe that if they haven't had vaginal sex they're still virgins. Some STDs can be transmitted through intimate skin-to-skin contact, even when there is no penetration.
