Is it dangerous to have herpes during pregnancy?
Although many women who have herpes during pregnancy go on to deliver healthy babies, the virus can cause some problems while you are pregnant. There is also a risk that the virus could be passed on to the baby while you are giving birth.
If you develop genital herpes for the first time within the first 26 weeks of pregnancy (through the first or second trimester of pregnancy), you could be at a higher risk of miscarrying. The risk of passing the virus on to your unborn baby is also high.
If you experience a herpes attack for the first time after week 27 (the third trimester of pregnancy) then the risk of passing the infection to the foetus is much higher. To prevent passing the virus on to your baby, you may be advised to have a caesarean section. This removes the risk of passing the virus on to the baby during a vaginal birth.
If you have active genital herpes blisters or sores present and you give birth vaginally, there is a high chance of passing on the virus to your baby.
