A sexually transmitted disease (STD), also called sexually transmitted infection (STI) or venereal disease (VD), is a disease transferred from one person to another through the act of having sex. The definition of sex includes all forms such as vaginal, oral, and/or anal. While sex is the most probable mode of transmission, STDs can also be transmitted during child birth, breast feeding, or contaminated drug needles.
STDs can result in a number of health problems if left untreated. STDs can cause cervical cancer, various abnormalities in pregnancy, and even cause damage to organs like the kidneys. When used correctly, condoms greatly decrease the chances of catching an STD; however, abstinence is the only full proof method of preventing an STD. I strongly encourage you to talk to your parents or healthcare provider to assess your risk and to gain the knowledge needed to protect yourself from curable (chlamydia, gonorrhea, or syphilis) and incurable (HIV and herpes) STDs.
