Can herpes cause baby problems?

Herpes and pregnancy. A mother can infect her baby during delivery, often fatally. But if a woman had genital herpes before getting pregnant, or if she is first infected early in pregnancy, the chance that her baby will be infected is very low -- less than 1%. Women with genital herpes are examined carefully for any symptoms before giving birth. If sores or signs that an outbreak is coming a c-section is done.
