Rubella antibodies include rubella IgG and rubella IgM. Through the testing of rubella antibodies along with the patient's clinical symptoms, many cases can be diagnosed. If rubella is definitively diagnosed, it generally requires appropriate isolation. Patients with mild conditions usually do not need hospitalization and can isolate at home. The main treatment is symptomatic management; generally, no medication is needed if there are no obvious symptoms, and complete recovery can be expected in about two weeks. If there are symptoms like fever and pain, medications such as antipyretic analgesics and pain relievers can be used for treatment and management, and a real-time assessment should be made based on the actual situation.

"Rubella virus positive" means what?

Rubella virus positive, in fact, most cases are diagnosed through blood tests for rubella virus IgG antibodies or IgM antibodies. It depends on which specific indicator is tested. If the IgM antibody is positive and the IgG antibody is negative, it indicates an ongoing infection. If both IgG and IgM antibodies are positive, it can be diagnosed as a rubella virus infection. If the IgG antibody is positive and the IgM antibody is negative, it indicates a past infection with no current rubella virus infection. If the rubella virus is cultured or detected in nasal secretions or blood, a definitive diagnosis can be made.

What does it mean if rubella virus IgG antibodies are high before pregnancy?

Before pregnancy, it is generally necessary to undergo eugenic prenatal tests, and the rubella virus test is one of them. If the test shows that rubella virus IgG antibodies are elevated, this indicates that the patient has previously been infected with the virus or has been vaccinated against the rubella virus, and antibodies have been produced in the body, providing immunity to the virus. Therefore, when a rubella virus IgG is detected, the patient does not need to be particularly worried, as this result does not affect a normal pregnancy. Regardless of whether or not one has been vaccinated against rubella, it is advisable to avoid contact with children infected with rubella during early pregnancy to prevent contracting the rubella virus, which can affect the growth and development of the fetus.

What are the symptoms of rubella virus?

Rubella occurs after infection with the rubella virus, which is a contagious disease. The typical clinical symptoms are fever, rash, and swelling of the lymph nodes behind the ears and at the back of the head. Generally, the clinical symptoms are relatively mild, the course of the disease is relatively short, and the prognosis is mostly good. However, if a pregnant woman is infected in the early stages of pregnancy, it can potentially affect the growth and development of the fetus. Transmission can occur through ordinary droplets, respiratory transmission, or close contact between individuals. In terms of treatment, there are no specific drugs, and many patients can recover in about two weeks without treatment.

Does rubella virus affect pregnancy?

A positive rubella virus infection indeed affects pregnancy, as the rubella virus can enter the fetus through the placental barrier, thereby easily leading to stillbirth, miscarriage, and fetal deformities. Therefore, if women of childbearing age are infected with the rubella virus, they should not get pregnant at this time. It is safer to wait until the condition has fully improved before attempting to conceive. In the early stages of pregnancy, if infected with the rubella virus, a decision on whether to continue the pregnancy should be made under the comprehensive assessment of an infectious disease specialist and an obstetrician/gynecologist, taking into account the actual situation for appropriate treatment and management.

The impact of rubella virus on the fetus

During pregnancy, if the pregnant woman is infected with the rubella virus, the impact on the pregnant woman herself is not significant; however, it primarily causes severe effects on the fetus. The main impact on the fetus is congenital damage, primarily involving congenital developmental abnormalities, with the early stages of pregnancy being the most critical. This period is a crucial phase of fetal development. If infected with the rubella virus, the risk coefficient can be as high as 80%. After intrauterine infection of the fetus, some patients may develop congenital rubella syndrome, primarily involving cardiac defects, cataracts, deafness, and even delayed brain damage after the baby is born.
