Endometritis
This type of HSV infection occurs in a woman with no evidence of prior infection
Primary HSV
This type of HSV infection occurs in a woman with a history of heterologous infection (i.e., first HSV-2 infection with a prior HSV-1 infection)
Nonprimary first episode

Recurrent infection
Which type of HSV infection poses the greatest risk to the fetus?
Primary infection
During labor, if you see herpetic lesions, or suspect the patient has herpes, what is the appropriate course of action?
Perform a C section and give acyclovir
When do you give acyclovir to patients with herpes?
Begin treatment at 36 weeks

38 weeks
Can a mother pass on HIV via breast milk?
Yes

Laryngeal papillomatosis
Complications of syphilis infection on the baby
