Fetal infection: mother-placenta-fetus
Factors of fetal infecion risk were evaluated in this article using analysis of anamnestic data from mothers of 705 deadborns (i.e. fetus}, died newborns and children who died on the first year of their life; screening virusological examination of 4322 pregnant and non-pregnant women was made; the results of pathological and virusological examinations of 1 80 placentas and organs prints from decedents were presented as well. It was stated that fetal infection in most cases has got a mixed etiology and chronic persistent development. The actions to prolong and carry out the pregnancy in case of threatened miscarriage have led to significant decrease of relative number of prematures, including children with low and extreme low body weight between examinated cases of deadborns and died newborns after 2000 year, versus the period before 2000. However the relative number of primitive fetuses between matures and died newborns has increased.
