Herpes does not affect a woman’s capability of being able to have children. At a recurrent herpes infection the risk of infecting the child is small, since the child is protected by the antibodies of the mother, and since the number of viruses is smaller than during a primary infection. The risk of infecting the child is at its highest when the mother has a primary outbreak of genital herpes at the end of the pregnancy. In this case it is recommendable to take a test from a suspected blister formation and also a blood test to make sure that it is not a herpes infection. If a pregnant woman has visible sores caused by a herpes infection when she is going to deliver, many clinics will perform a caesarean to prevent the infection from transferring to the child. You should inform your midwife if you have genital herpes.
Be aware that antiviral drugs for treating herpes such as Aciclovir may be harmful to the foetus, and may harm the child when you are breastfeeding. Consult your doctor before taking medication if you are pregnant or breastfeeding.
