The most dangerous viral sexually transmitted disease is the human immunodeficiency virus (HIV), which leads to AIDS. Other incurable viral STDs include human papillomavirus (HPV), hepatitis B, and genital herpes. In this presentation, genital herpes will be referred to as herpes. Chlamydia and gonorrhea can cause PID and infertility, but both can be prevented.
To have a healthier baby, ask your doctor about testing for STDs. This is a bacterial infection that can be life-threatening due to vaginal, anal, or oral sex. It can spread if the sores caused by syphilis touch a healthy person's skin. Sores can be found on the penis, vagina, anus, rectum, or on the lips and mouth.
Syphilis can also be transmitted from an infected mother to the fetus.
