Rubella virus infection is another killer of fetus inheritance. It mainly occurs in winter and spring, and is transmitted through the airborne droplets. Humans are the only source of infection, and the secretions from the mouth, nose, and clothing of patients can also contain rubella virus.
Therefore, it is common for women to test for rubella virus before pregnancy. For those who have reported rubella virus IgG, this may be a relatively unfamiliar concept to many.
What does the IgG antibody for rubella virus specifically mean, and what does "positive" and "negative" represent? The IgG antibody for rubella virus represents immunoglobulin G, which indicates an antibody response to the rubella virus in the human body. A positive result means that a person has developed antibodies (either IgM or IgG) against the rubella virus. If no antibodies are detected, it is considered negative. In women of childbearing age, especially during early pregnancy, infection with the rubella virus can cause fetal intrauterine infection, leading to congenital rubella syndrome. Therefore, understanding whether an individual has been infected with the rubella virus and its antibody levels is crucial for prevention and treatment of this complication.
Therefore, many women undergo prenatal testing for rubella virus before becoming pregnant. Consequently, one often hears about the term "IgG to rubella." What does IgG stand for, and why is it important? If a person's test results indicate a positive result for IgG to rubella, it means that they have already been infected with the rubella virus and developed immunity, making it unlikely that the fetus will be infected.
If a person's test result reads "Rubella virus IgG negative," it means that the person has not been infected with rubella virus.
So, is it enough to look at the RSV IgG? The answer is no.
If the rubella virus IgG is positive, the rubella virus IgM also needs to be checked. If the rubella virus IgM is positive, then the rubella attenuated live vaccine should be administered, and contraception should be used within three months after vaccination.
If the result of RSV IgM is negative, then you can be sure to have a safe pregnancy.
The normal range for rubella virus is an IgM antirubella antibody negative and IgG antirubella antibody negative.
Anti-rubella virus IgM antibodies are primarily used for the diagnosis of acute rubella infection, with anti-rubella virus IgM appearing in serum 2 weeks after infection.
Additionally, it is important to note that in the early stages of pregnancy, expectant mothers should minimize their exposure to public places and avoid contact with individuals who have rubella.
Rubella virus IgG positive, rubella is a viral infectious disease. As patients often present with generalized rash, there is certain harm to the skin of the patient. Understanding the significance of RV—Ab, this test is an indicator for determining whether or not a person has been infected with rubella virus, with a negative result or IgG Ab less than 1:512.
The laboratory detection of rubeola virus is conducted by drawing venous blood, and detecting the IgG and IgM antibodies against rubeola virus in the body.
The peak incidence of rubella virus occurs from spring to early summer, while the positive rate of rubella virus antibody increases with age. Newborns can acquire rubella virus IgG antibodies through an infection by a mother who has been infected in her earlier years.
The IgM antibody response begins to appear approximately 4 days after the onset of rash, peaks around 10 days, and persists for 6 to 12 weeks, although it may occasionally persist for up to a year.
The IgG antibody appears later than the IgM antibody, gradually increases, reaching a peak at 1 to 2 months and then declines. It is maintained throughout life in more than 80% of the population.
The positive result for rubella IgG antibodies indicates that one has been previously infected with the rubella virus. IgG antibodies are produced by the body after initial infection, usually weeks or months later. Once infected, IgG becomes permanent and does not affect the individual's health.
However, it is not enough to solely conclude that one can become pregnant based on a positive result for rubella IgG antibodies.
When the rubella virus IgG is positive, it is necessary to ensure that the quantitative titer of the CMV IgG antibody is negative in order to be able to conceive. This will not affect the development of the baby.
Individuals who have never been infected with measles, mumps, or rubella and have not received the measles, mumps, or rubella vaccine are generally susceptible to infection. Adults can also become infected, especially women preparing to become pregnant, who should receive the vaccine at least three months before conception. Infection during the early stages of pregnancy, particularly in the first three months, can lead to miscarriage, stillbirth, or congenital defects in newborns.
Because the measles-mumps-rubella (MMR) combined vaccine is a attenuated live vaccine, women of childbearing age should avoid pregnancy for 3 months after vaccination.
From the point of view of eugenics, it is necessary to get measles-mumps-rubella vaccine. If you have money, it is better to get vaccinated, so that your baby will be protected.
If a woman wants to have a healthy baby, she should make sure her health is in good condition, especially for rubella IgG.
It's important to know that if a pregnant woman is infected with the rubella virus IgG during pregnancy, it can cause fetal malformations.
Therefore, only after a negative diagnosis of rubella IgG is it recommended that you become pregnant.
Rubella virus IgG is more prevalent in children and adolescents, but because pregnant women have lower immune capabilities, they are also more susceptible to infection during pregnancy.
Moreover, the IgG antibody to rubella virus poses a greater risk to children, so it is imperative that pregnant women pay close attention.
If you are IgG negative for rubella virus, it proves that you have never been infected with rubella and have not received any relevant antibody vaccines. This poses significant risks to both pregnant women and fetuses, as rubella virus can easily cause miscarriage, malformation, slow or even incomplete development of fetuses, posing great harm to the fetus. Moreover, rubella virus can be transmitted through airborne droplets, so it is best to have a certain level of self immunity before pregnancy. At the same time, rubella vaccine is the only vaccine in eugenics that can provide long-term immune protection to the human body and has no sustained harm to the human body. As long as you produce antibodies in your body after receiving the vaccine, you will have no worries about pregnancy six months later. So there is no need to worry about the impact on the fetus. The impact of drugs on the fetus refers to the toxic effects that medication during pregnancy can have on the fetus.
However, for those who were infected with rubella virus IgG during childhood, there is no need to worry about this issue. Because it is a disease that a person will only suffer from once in their lifetime, which means that if they have been infected with rubella virus IgG, their antibodies will be present in their body.
How is rubella virus transmitted? As is well known, rubella is a highly contagious disease, and the human body is generally susceptible to this virus, especially in infants after 6 months of age who are still developing without the protection of maternal antibodies.
Moreover, due to a compromised immune system, it is a high-risk group.
How is rubella transmitted? 1. Infectious sources: Rubella patients, asymptomatic carriers, and congenital rubella patients are all sources of transmission of this disease, and the incubation period of rubella is 14-21 days.
2. Routes of transmission: It is mainly transmitted through airborne droplets and via the placenta to the fetus, as well as through close contact between individuals.
Infants born to mothers infected with viruses may emit the viruses in their throats for several weeks, months, or even years. Therefore, they can be infected through contaminated breast milk bottles, nipples, clothing, and underwear, as well as through direct contact with healthcare personnel and family members who lack antibodies. This can also lead to transmission within the nursery.
3. Susceptible Population: The general population is susceptible to rubella virus and can develop long-lasting immunity after infection.
Infants under 6 months old, due to the presence of antibodies from the mother's body, acquire resistance and rarely develop illnesses.
In the first year of life, as immunity wanes with increasing age, children become susceptible, so they are most commonly found in children aged 1-5 years old.
The majority of adults have antibodies, but they can still occasionally develop an illness.
Women of childbearing age are more susceptible to rubella and have a more lasting immunity.
Humans are the sole natural host of the rubella virus, and it is transmitted by droplets. The virus is most infectious before, during, and after the rash appears. It can also be found in the blood, feces, and urine.
Hence, in daily life, people should pay special attention to it, especially to the population of babies and women of childbearing age.
