What are the risks of parvovirus during pregnancy?
Parvovirus B19, also known as the fifth disease, is a common rash that occurs in children. While the fifth disease in children is usually mild and cleans itself, Parvovirus in pregnancy can be very risky both for both mother and fetus. The risks of parvovirus during pregnancy include abortion and fetus anemia. Fortunately, many women are already immune to the virus and the risk of passing the placenta to the fetus is very low.
More than 50 percent of women have immunity to the virus, probably because they had a fifth illness as children. Their immunity protects the fetus. A woman who is worried about being exposed to a virus during pregnancy can perform a blood test. The test will determine whether it has recently been exposed to a virus, whether it has built immunity before previous infection.
If an immune woman is exposed during pregnancy, there is a 33 % chance that the virus will pass through the placenta to Fetus. The risk of damage to the fetus exposed to parvovirus is usually the largest in the first 20 weeks of pregnancy. These fruits can develop HYdrops fetalis, a serious case of anemia that can lead to abortion. In several cases, the child may be dead.
abortion usually occurs only in about 5 percent of all parvovirus cases in pregnancy. If the mother is exposed later in her pregnancy, after 20 weeks her child will usually be fine. Parvovirus during pregnancy does not cause other problems in the child, such as congenital defects or mental retardation.
After the blood test, it confirms that the woman was exposed to parvira, her doctor will monitor the fetus with ultrasound to seek outlines of hydropics, as well as enlarged placenta or excess amniotic fruits. If any evidence of the risk of fetus is found, the doctor extracts a small sample of the fetal blood to try anemia. Anemia may be treated with blood transfusion from the mother if necessary.
may be difficult to prevent parvoviru exposure while the woman is pregnant. Many people with a virusIt does not show symptoms until they are contagious for several days and some never show symptoms. A pregnant woman should avoid sharing glasses and dishes with anyone and should often wash her hands.
