Sexually transmitted diseases are a group of diseases contracted mainly through the sexual act, without protection (condom), where there is exchange of fluids from the genitals. However, these diseases can also be transmitted by blood and in some cases can be transmitted from mother to child during childbirth.

Using condoms in all sexual relations is the most effective method for reducing the risk of STD transmission, especially the AIDS virus, HIV. Another form of infection may occur through transfusion of contaminated blood or sharing syringes and needles, especially in injecting drug use. AIDS and syphilis can also be transmitted from the untreated infected mother to the baby during pregnancy, childbirth. And in the case of AIDS, also in breastfeeding.
