Symptoms include bumps in and around the genitals. Spreads through any sexual contact (anal, oral, and vaginal), and also by skin to skin contact. A vaccine exists to help prevent this disease. Which of the following STIs is this?

Choice A reason: Congenital anomalies of the central nervous system are not a common complication of GDM, as they usually occur in the first trimester, before GDM develops. However, GDM can increase the risk of other congenital anomalies, such as cardiac defects or neural tube defects.

Choice B reason: Preterm birth is a possible complication of GDM, as it can be caused by maternal hypertension, preeclampsia, or placental abruption. However, it is not the most likely complication, as GDM can also delay the onset of labor and prolong the pregnancy.

Choice C reason: Low birth weight is not a typical complication of GDM, as it is more associated with intrauterine growth restriction (IUGR), which is caused by placental insufficiency. GDM can cause the opposite problem, which is excessive fetal growth.

Choice D reason: Macrosomia is the most common complication of GDM, as it is defined as a birth weight of more than 4,000 grams (8.8 pounds). It is caused by the excess glucose crossing the placenta and stimulating the fetal insulin production, which leads to increased fat deposition and organ enlargement. Macrosomia can increase the risk of birth trauma, shoulder dystocia, and neonatal hypoglycemia.

Choice A reason: HPV is a common STI that causes genital warts and can lead to cervical cancer. It can be transmitted by any sexual contact or by skin to skin contact. A vaccine is available to protect against some strains of HPV.

Choice B reason: Genital herpes is an STI that causes painful blisters and sores on the genitals. It can be transmitted by any sexual contact or by skin to skin contact. There is no vaccine for genital herpes, but antiviral medications can reduce the symptoms and frequency of outbreaks.

Choice C reason: Chlamydia is an STI that causes inflammation and discharge from the genitals. It can be transmitted by any sexual contact. There is no vaccine for chlamydia, but antibiotics can cure the infection.

Choice D reason: Gonorrhea is an STI that causes pain and discharge from the genitals. It can be transmitted by any sexual contact. There is no vaccine for gonorrhea, but antibiotics can cure the infection.
