Rubella - a common infectious-viral disease, which is more often noted in children. However, the ability to catch and rubella with age does not pass. In adults, this childhood disease is particularly difficult, causing complications.
Pregnancy and rubella a very dangerous combination. The harmful effects of this disease on the fetus were known long before the virus was detected and the causes of the disease were clarified. Our ancestors girls led to children suffering from rubella, so that they had an illness at a young age, and pregnant, gave birth to healthy children. By the way, this is still the case.
Rubella is distinguished by the selective effect of the virus on the fetal tissues, which depends on the period of pregnancy. The disease is caused by viruses, and they in the body tend to hit the youngest tissue.
Term of pregnancy and rubella
Different systems and organs are formed at different periods of pregnancy. If the disease develops at a period of 3-11 weeks, the brain is usually affected, 4-7 weeks - eyes and heart, 7-11 weeks - hearing organs. In the early stages of pregnancy often occurs a combination of lesions, frequent incidents of miscarriages.
Rubella in the pregnant for a period of up to 16 weeks of pregnancy - a medical indication for its interruption.
At later terms, when the child's systems and organs were formed, he suffers from a decrease in immunity, anemia and other consequences of rubella. And the severity of the lesion does not depend on the severity of the disease of the pregnant woman. In this case, the issue of continuing pregnancy is decided on the basis of all factors, perhaps this pregnancy has come after many years of infertility.
It is believed that the risk of infection of the fetus after the third month of pregnancy is significantly reduced. Although, according to statistics, the probability of the birth of a sick child with a disease before 16 weeks of pregnancy is close to 100%.
Infection of the fetus with rubella
It is worth noting that infection of the fetus with rubella can occur after infection of his mother until the third trimester of pregnancy. There are data according to which intrauterine infection of the fetus was observed in women who developed rubella in six months or a year before conception, which is explained by the duration of the mother's preservation of viruses and their antigens.
There is still such a problem as a hidden disease. A pregnant woman was in contact with a sick rubella, but she did not seem to get sick herself. Even if the woman does not have symptoms of the disease, but the infection has occurred, the virus also affects the fetal tissues, just as with reliable rubella. To refute or confirm the disease need to take the analysis on M and immunoglobulin G. If both increased - the disease occurs, and if elevated immunoglobulin only the G - women's health and danger to her child there.
In addition to defects in the fetus, there may be signs of pregnancy complications such as stillbirth, miscarriage, early neonatal mortality, sepsis, and general underdevelopment. This pathology is caused by hyperthermia, general intoxication, fetoplacental insufficiency due to infection of the placenta and metabolic disorders.
During childbirth, rubella can cause obstetric complications associated with impaired labor, bleeding and septic complications.
