High rubella virus IgM antibodies have a certain effect on pregnancy. If you have high rubella virus IgM antibodies before pregnancy, it is recommended to strengthen your body’s resistance with exercise and regular re-examination. If the rubella virus IgM antibodies are still high, you need to give antiviral drugs such as acyclovir and ribavirin for active treatment. If the rubella virus is contracted in early pregnancy, it is likely to cause fetal malformations and even neurological deafness, and the pregnancy needs to be terminated promptly because there are no very effective drugs for treatment, and prevention is the key. Most women have had rubella at a very young age or have been vaccinated against it before they become pregnant, so the chances of contracting the rubella virus are very small.
