Can HPV Be Transmitted During Delivery?In rare cases, a pregnant woman can pass HPV to her baby during vaginal delivery. A baby that is exposed to the virus can develop warts in the throat or voice box (known medically as laryngeal papillomatosis). These warts appear predominately in preschool children and can block the breathing tubes, causing potentially life-threatening breathing problems.
Because this is so uncommon, however, most healthcare providers do not recommend a cesarean section (C-section) for women with genital warts at the time of delivery.
