Congenital herpes simplex
Other Names: Congenital herpes simplex virus infection; Antenatal herpes simplex virus infection; Mother-to-child transmission of herpes simplex virus infection
This virus causes recurrent cutaneous infections in adults, often involving the lips or the genitalia. Herpes infections in other organs, such as the liver or central nervous system, are less frequent.
Skin lesions and scars, chorioretinitis, microcephaly, hydrencephaly, and microphthalmia have been described in infants with in utero primary herpes virus infections, but a causal relationship between these manifestations and the infection could not be established.
For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed.
30%-79% of people have these symptoms
- Intrauterine growth retardation
- Prenatal growth deficiency
- Premature birth
- Premature delivery of affected infants
5%-29% of people have these symptoms
- Abnormally small skull
There are two types of virus (HSV-1 and HSV-2) and both appear to have the same activity.
It has been suggested that latent HSV-2 infections occur in as many as 20 to 40% of women.
Exposure of the foetus to herpes virus at the time of delivery carries a serious risk of infection for the newborn. This risk may be high during the initial infection of the mother (33 to 50%), but probably does not exceed 3% in cases of reinfection because of the protective effect of maternal antibodies.
It remains difficult to distinguish between cases with a primary infection and those with a previously undetected recurrent infection that has become symptomatic during pregnancy.
Management and treatment
In spite of described cases of serious foetal illness, primary infection with herpes virus during pregnancy is not an indication for therapeutic abortion, and the use of antivirals in the treatment of primary herpes infections during gestation has been recommended.
Some authors recommend caesarean delivery for women with first-episode genital herpes lesions at the time of delivery.
