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. Take the rubella virus for example. Pregnant women generally undergo very detailed and frequent checks for the rubella virus during pregnancy. If a pregnant woman is tested positive for rubella, her pregnancy will be at risk.

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 exactly is the role of rubella virus antibodies?

Rubella virus belongs to the togavirus group of arthropod viruses and is the pathogenic virus of rubella. The virus particles are pleomorphic, 50-85 nm, and have a coating. The particles contain RNA (infectious nucleic acid) with a molecular weight of 2.6-4.0×106. It can be inactivated by ether and 0.1% deoxycholate, and is also weakened by heat.

Rubella virus is an RNA virus belonging to the Togaviridae family and is a virus limited to humans. Under an electron microscope, the virus appears as an irregular sphere 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, ether, cesium chloride, deoxycholic acid, etc. pH < 3.0 can inactivate it.

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.

Therefore, the rubella virus antibodies in the human body will resist foreign rubella viruses. When the rubella virus invades the human body, it will be killed to ensure the health of the human body.

Medical technology is becoming more and more advanced nowadays, so women who want to get pregnant, regardless of whether you have been infected with the rubella virus before, must go to the hospital on time to get the rubella vaccine in the six months before preparing for pregnancy. This will protect our bodies against the rubella virus. Only in this way can we devote ourselves wholeheartedly to pregnancy without worries and prepare to welcome the arrival of a new life.
