Rubella virus during pregnancy infection

Pregnant woman Wang (pseudonym) was more than 1 month of pregnancy:

Specifications, accompanied by fever, went to the hospital for examination and found that the rubella virus antibody was positive.

It ’s okay after a week. I did n’t care. After the baby was born:

Hearing inspection was not passed several times, it was confirmed to be severe deafness, and the heart ultrasound also prompted congenital heart disease.

Wang’s encounter is a real case:

The infection of rubella virus during non-pregnancy may be just low fever, headache, throat pain, fatigue, etc. as uncomfortable as ordinary colds. After 1-5 days, some rash will appear throughout the body.question.

However, the impact on the baby during pregnancy cannot be ignored.

Infection before 12 weeks of pregnancy, more than 90%of the palace infection occurs;

Infection from 13-14 weeks, 54%of infection will occur;

Infection after 20 weeks of pregnancy, babies generally do not cause malformations;

In -palace infection, the baby will cause one or more organ damage:

Feeling neurotic deafness: the most common; congenital heart disease: arterial ducts are not closed, pulmonary stenosis, ventricular septal defects, room septal defects, Followy four couplets, etc.; eye defects: congenital cataracts, glaucoma, small eyes and small eyes andPigphine retinopathy, etc.; Central nervous system lesions: small head deformity, meningitis, slow development, low intelligence; long -term sequelae: diabetes, precocious puberty, carrier whole encephalitis, etc.

Blood check rubber virus antibody IgG and IGM!

1. What situation needs to be checked?

Prepare pregnancy;

In contact with rubella, patients have to check;

During pregnancy, there are cold fever, throat pain, headache and other cold symptoms.

2. Results interpretation:

IGG and IGM are negative:

There is no infection with rubella virus, but because there is no antibody, it is prone to infection. If you are not pregnant, you can inject rubber vaccines. If you are pregnant, if you are exposed to a patient with rubella or have cold symptoms, review after 2-3 weeks, if IGG/IGM turns positiveIt is the first rubella infection. If it is still negative, it means that there is no infection;

IgG positive, IGM negative: previous infection, those who are not pregnant can be pregnant;

IgG positive, IGM positive: reviewing IGG titer, if IGG titer increased by more than 4 times within 4 weeks, considering the infection again, those who are not pregnant should postpone pregnancy;

IGG negative, IGM positive: acute infection, review after 2 weeks, if IGG is positive, it is determined to be acute infection, and those who are not pregnant should postpone pregnancy. If IGG is still negative, it is not acute infection and false positive.

Infection during pregnancy, it ’s good to say, delay pregnancy, but if it is pregnancy infection?

At present, there is no treatment that can improve the ending of the infection of the baby’s palace. Therefore, the pregnant mother is determined to be a first rubella virus infection within 12 weeks. It is recommended to terminate pregnancy. After more than 20 weeks, because the possibility of deformity is very small, there is no need to terminate pregnancy.It’s right.

Vaccination is an effective measure to prevent rubella virus infection, so it is recommended:

All pregnant women conduct a rubella virus examination. If IGG and IGM are negative, they are vaccinated first, and they are planned to be pregnant after 1 to 3 months of contraception.


If you get pregnant unexpectedly after vaccination, you don’t have to terminate your pregnancy;

One month before pregnancy and after pregnancy cannot be vaccinated.
