Cytomegalovirus (CMV) IgM
Cytomegalovirus infection is detected during the acute period. CMV IgMs appear in the blood as early as 3-4 days after the start of infection and persist for several months (after which they degrade).
Cytomegalovirus (CMV) IgM – an increase in IgM antibodies to Cytomegalovirus indicates a primary active infection or an exacerbation of chronic infection. Cytomegalovirus (CMV) is widespread worldwide. The infection is transmitted through airborne droplets, sexual contact, body fluids (blood, saliva, urine, faeces or milk (when breastfeeding a baby).
The most serious consequences of the virus occur when the foetus in the mother’s womb becomes ill. Early pregnancy can lead to fetal death in utero, developmental abnormalities in various organs and heart defects. Late pregnancy increases the likelihood of premature birth, hearing and optic neuritis, mental and physical impairment, and death in the early days. According to statistics, the risk of transmission to the foetus can be as high as 50% if a primary infection occurs during pregnancy. Testing for cytomegalovirus (CMV) IgM and IgG antibodies against cytomegalovirus is recommended before pregnancy. People with malignant diseases, AIDS, severe congenital immunodeficiency, blood transfusions or organ transplants are also at risk.
In rare cases, in immunocompromised people, the disease is mild, with symptoms similar to influenza or infectious mononucleosis.
