Rubella virus antibodies are high

The harm caused by rubella virus is actually quite serious, especially for pregnant women. Pregnant women have weak constitutions and poor resistance. Once infected with rubella virus, it is easy to cause fetal malformations, which seriously affects family life. Rubella virus infection can also cause swollen lymph nodes and lead to pharyngitis and rhinitis, which are not easy to treat, so remember to get the rubella virus vaccine in time.

1. What is Rubella virus antibody?

Generally, pregnant women need to undergo various examinations at different stages of pregnancy to ensure their health, the good growth of the fetus, and the smooth birth of the fetus. As for the rubella virus, pregnant women generally undergo very detailed and frequent checks on the rubella virus during pregnancy.

Although most women in our country have been infected with the rubella virus, for safety reasons, women will be injected with the rubella virus vaccine six months before they are ready to become pregnant so that they will have rubella virus antibodies in their bodies and thus resist infection with the rubella virus. So, what is the role of rubella virus antibodies?

Rubella virus belongs to the togavirus group of arthropod-mediated viruses and is the pathogenic virus of rubella; the virus particles are pleomorphic, 50~85 nanometers, and have a coating; the particles contain RNA (infectious nucleic acid) with a molecular weight of 2.6~4.0×106; * and 0.1% deoxycholate can inactivate it and it is also weakened in heat.

Rubella virus is an RNA virus belonging to the Togaviridae family and is a virus limited to humans. Under an electron microscope, it appears as an irregular spherical shape with a core diameter of 50 to 70 nm. The antigenic structure of the rubella virus is quite stable, and only one serotype is known.

Rubella virus is prone to vertical infection. After a pregnant woman is first infected with rubella virus in early pregnancy, the virus can enter the fetus through the placental barrier, often causing miscarriage or stillbirth. It can also cause congenital rubella syndrome in the fetus and cause fetal malformations. The virus has weak vitality outside the body and is sensitive to ultraviolet light, *, cesium chloride, deoxycholic acid, etc.

Rubella virus is not heat-resistant and can be killed at 56°C for 30 minutes or at 37°C for 1.5 hours. It is unstable when stored at 4°C and is best stored at -60 to -70°C to remain active for 3 months. It can be stored for 9 months when kept dry and frozen.

2. What is a positive Rubella virus antibody?

If a person is infected with the rubella virus, it will cause very serious harm to the body, especially for pregnant women. If infected with the rubella virus, the chance of fetal malformation will be very high. Therefore, many women will undergo rubella virus tests before preparing for pregnancy, and many women’s diagnosis results are positive for rubella virus antibodies. What’s going on?

When the rubella virus antibody test is positive, many people will think that they are infected with the rubella virus, but this is not the case. The so-called positive rubella virus antibody means that the body has a certain resistance to the virus, proving that it will not be infected with the rubella virus.

Rubella is a relatively common disease in early childhood. Although it is similar to urticaria, it is much milder than urticaria, so it is also called "three-day measles". However, if the virus that causes this disease infects a pregnant woman, it can invade the fetus and cause birth defects, so it has attracted much attention.

If the rubella virus enters the body of a person who has not been infected with the rubella virus, it will cause swelling of lymph nodes throughout the body around the 8th day after invasion; fever has not yet appeared at this time, but from this time on, the virus will appear in the blood (if the person is pregnant, the fetus will be infected at this time); syphilis will also appear in the throat, nose and rectum.

After a child is infected with the rubella virus, about half of them will have a fever at the same time as the rash appears. Although the virus can no longer be detected in the blood at this time, the virus may remain positive in the throat, nose, and stool for 3 weeks. In fact, you are no longer contagious one week after the rash appears. If there is a child nearby who has rubella, when he goes to kindergarten after recovery, pregnant women before 16 weeks of pregnancy should not have contact with him within 3 weeks.
