Patients infected with rubella virus usually have mild symptoms, including a sudden onset of fever, headache, malaise, sneezing, coughing and sore throat, followed by a rash that extends from the face to the body. However, the rash will subside after 3 days, the body temperature will drop, and the illness will recover quickly. However, if the rubella virus is present in the body, once pregnancy occurs, especially during the second trimester, when the fetal organs and tissues are developing, it can invade the placenta and transmit to the fetus, causing congenital abnormalities and rubella syndrome. I. How is it treated? There is no effective treatment available. However, early in pregnancy, your doctor can know if you already have antibodies through a blood test. If you are negative, you will need to be tested monthly until the fifth month of pregnancy. Prevention strategies: Currently, prevention is the main focus for rubella virus. Since people who have had rubella can gain lasting immunity and are no longer infected by the rubella virus, women of childbearing age, especially those who have had negative anti-rubella virus antibody tests, can receive the attenuated rubella virus vaccine before pregnancy to gain lifelong immunity. Women who want to become pregnant should avoid contact with rubella patients by going to crowded public places as little as possible. In case of inadvertent contact with a rubella patient after pregnancy, gammaglobulin should be administered within 5 days of contact for some protection. Make sure you are not pregnant before vaccination and do not plan to become pregnant within 3 months to avoid infection of the embryo by the attenuated virus in the vaccine.
