Genital herpes during pregnancy is dangerous only when the woman caught him the first time. If the genital herpes was with her, and before pregnancy, as a rule, it is not dangerous for the mother and the fetus itself, safely protected from any adverse effects of fetal membranes and placenta.
Pregnancy and recurrent genital herpes
Many women suffering from recurrent herpes for a long time, I doubt whether they can give birth to a healthy baby. Of course, no good combination of genital herpes in pregnancy is not. However, it was found that in patients with recurrent herpes in women develop antibodies that inhibit the too high activity of infectious agents - herpes simplex virus
Herpes simplex - in fact, not so simple
I and II (HSV - HSV I and II). Fetal membranes and placenta reliably protect the child from the virus, so intrauterine infection in the overwhelming number of cases can be avoided.
But the woman have to inform obstetricians and gynecologists that suffers from genital herpes. During pregnancy, the survey is conducted before delivery addressed the issue of whether it is possible for a woman to give birth alone. This is possible only in the case where four weeks before birth in smears from the walls of the cervical canal
Cervical canal - the path traversed by every person
HSV is not detected (usually using PCR that detects viral DNA).
If a woman during pregnancy often have recurrences of genital herpes or herpes found on the birth canal a few weeks before delivery, the delivery is best done by Caesarean section, as too great a risk of infection of the fetus during its passage through the birth canal. After a Caesarean section the risk of infection of the child is virtually zero, and later the child is developing normally.
If a woman gives birth alone in the fact that in her birth canal detect the presence of the causative agent of genital herpes, the risk of infection of the child is very large. He can begin a primary herpes, which is in the neonatal period often takes generalizovannnoe for, that is applied to the entire body from the visceral and brain. It's very heavy, difficult to treat disease.
Pregnancy and primary genital herpes
Primary genital herpes during pregnancy is very dangerous. In most cases, if a woman is infected in the first trimester, it is a spontaneous miscarriage
Miscarriage - can you protect yourself from it?
due to infection of the fetus. But sometimes infect the fetus can continue to develop - in this case, if the contamination occurred during the bookmark those or other bodies may be the birth of a child with developmental abnormalities. Primary infection danger at any stage of pregnancy, but particularly in the third trimester, after 24 weeks.
When the herpes simplex virus (HSV - I and HSV-II) for the first time enters the body of a pregnant woman, he can get to the fetus, as antibodies that prevent its spread in the body is not. They are produced only after some time. This leads to the development of intrauterine infection of the fetus and the birth of a child or a dead (in most cases), or with severe lesions of the internal organs and the brain. Intrauterine herpes infection is difficult to treat. If a child survives, it remains disabled for life.
But it is not all that bad. Sometimes for the primary manifestations of genital herpes during pregnancy is accepted its recurrence, if earlier, before pregnancy, the disease is asymptomatic. It happens often enough and a herpes usually does not threaten the pregnancy.
Sometimes the herpes virus is detected during pregnancy in the survey, but she claims that she never had this disease before. What to do? Surveyed more detail.
How to distinguish a primary genital herpes recurrence of previously asymptomatic infection?
To do this, a DNA detection of HSV - I and HSV II by PCR little. The analysis for the presence of antibodies in the female body to various types of HSV. During the initial implementation of HSV in the human body in the blood are no antibodies (proteins, immunoglobulins, act aimed at the destruction of a particular antigen, eg, HSV) to this pathogen infection. But after a while they appear. The first two weeks after infection appear immunoglobulin M (IgM - first line of defense) and then after a while the content of IgM is reduced (they are contained in the blood up to four weeks), but there are immunoglobulin G (IgG), the concentration of which increases and persists throughout life - it says about the current stable immunity
Immunity - types and characteristics in children in adults
Determination of blood IgM and IgG antibodies is performed using ELISA (enzyme-linked immunosorbent assay), which may be qualitative and quantitative. With IFA can identify the type of HSV, and the disease is a manifestation of primary or recurrent herpes.
It is this analysis will help the doctor determine the tactics of pregnancy. A doctor or reassure the woman in the case of confirmation of recurrent genital herpes, or explain what is the danger of the state (for confirmation of primary herpes). Management of pregnancy in the latter case shall be elected individually.
