There is a lot of controversy about the treatment of genital herpes in pregnant women, focusing on whether nucleoside analogs can be used in pregnant women and whether they can achieve recurrence control after use. 2000 CDC guidelines for the treatment of STDs recommend that pregnant women with primary genital herpes have a 30% to 50% incidence of mother-to-child transmission during delivery via the birth canal due to factors such as prolonged virus discharge, frequent cervical involvement, large damage area, and lack of protective antibodies. The incidence of mother-to-child transmission during delivery is 30% to 50%, so a cesarean section is needed to prevent mother-to-child transmission.
