The State of Health of Children of the First Year of Life, Depending on the Period of Infection with Cytomegalovirus

Cytomegalovirus infection (CMVI) is an actual problem of perinatology, as it is one of the most frequent congenital infections and occurs in 0.2% to 2.5% of newborns [1-4]. Congenital CMVI can occur both in severe form, in which a lethal outcome is possible, and in the forms of low-symptom and asymptomatic variants [2,4-7]. Low-symptom and asymptomatic forms often occur under the “masks” of various diseases. This is caused by the complexity of their diagnosis and the untimely appointment of therapy [5,6,8-11]. Thereby, it is interesting to study the effect of the persistence of cytomegalovirus (CMV) on the health status of children in the first year of life, which have the low-symptomatic and asymptomatic forms of congenital or early postnatal infection.
