Introduction
In general, rubella does not necessarily cause malformations, but there is a certain probability of causing birth defects. Rubella is an acute respiratory infectious disease primarily caused by the rubella virus. If a pregnant woman becomes infected with rubella during early pregnancy, the fetus may become infected via the placenta, leading to congenital rubella syndrome and potentially resulting in severe fetal malformations.
In general, rubella does not necessarily cause fetal malformations, but there is a certain probability of causing them. Rubella is an acute respiratory infectious disease primarily caused by the rubella virus. The specific analysis is as follows:
When pregnant women are infected with rubella during early pregnancy, the fetus may become infected via the placenta, leading to congenital rubella syndrome and potentially severe fetal malformations. If rubella infection occurs in early pregnancy, the risk of fetal malformations is relatively high, although malformations do not always occur. Rubella virus infection can lead to various congenital abnormalities in the fetus, including congenital heart defects, microcephaly, growth retardation, intellectual disability, congenital cataracts, and sensorineural deafness. Therefore, rubella infection during pregnancy poses significant risks, with a high teratogenic rate; in severe cases, it may even result in fetal demise or preterm birth.
Pregnant women generally have weakened immune systems, and once infected, serious consequences may follow. It is therefore essential to have a comprehensive understanding of this disease and to actively take preventive measures and seek timely treatment to minimize adverse effects on the fetus.
