What is cytomegalovirus (CMV) infection during pregnancy?
Although the disease often does not show any symptoms, some people may experience weakness, fever, and swelling of the lymph nodes 2-3 weeks after encountering the virus. The herpes group is a virus which is transmitted by the body secretions urine, sweat, semen, blood, breastfeeding. It does not pass through animals, water, food. It is contagious with close contact. It is more common in developed countries than in underdeveloped countries. Prenatal infants, people working in kindergartens, people with weak immune systems are more susceptible to infection. It can be difficult to diagnose because there is a possibility that it will pass without symptoms. Antibodies against the agent remain in the person's body for life. A blood test is used to investigate the causative agent, even if the test is negative, it should be checked again after 2 weeks. The virus can also be produced in secretions such as throat culture, urine, etc., but this is an expensive method. There is not much choice to test the fetus in patients with infection in pregnancy. Amniocentesis is performed and the fluid is sought for viruses. Fetus growth retardation, enlargement of brain tissues, decrease in amniotic fluid makes suspicion that fetus is affected. When the baby is born, the baby's saliva, blood and urine are sought for viruses. A healthy pregnant woman is not affected by the disease, but the fetus is at risk. The transition rate from mother to fetus is around 30-50%. After the mother's primary infection, 10% of the infected fetuses are born with congenital CMV infection. Congenital CMV infection rate in the world is between 0.2-2%. If CMV infection is secondary in mothers, the risk of congenital CMV is around 1%. And only 1 to 10% of these are found at birth. 15% does not give any symptoms at birth, but in the long term deafness and learning difficulties occur. Hand wash and soap are very important. Saliva-transmitted food transmits disease. Therefore, sharing food, using the same fork, spoon, etc. is inconvenient. In pregnancy controls, the causative agent of this disease should be investigated by blood test. Especially mothers with fever, swelling of the lymph nodes and fatigue should be aware of this disease. Again, it is important to be pregnant especially when the mother is pregnant at the time she has had this disease for the first time. There is no vaccine against the disease.
