Herpetic infection (genital herpes caused by herpes simplex virus Herpes simplex - actually not so simple type 2) is dangerous mainly for primary infection is during pregnancy.In primary infection in women do not have time to develop protective antibodies to the virus, and it can penetrate through the placenta to the fetus, causing fetal infection.Such complications are not always - the placenta protects the fetus from infection, however, with the primary infection and the risk is such women appointed antiviral therapy.
