During pregnancy viruses of high oncogenic potential--types 16, 18, 31, 33, 35, which had so far remained in the state of chronic infection, undergo reactivation. Among the potential ways of HPV transmission to foetus, the direct perinatal infection is mentioned. In the antenatal period of pregnancy, a descending way of infection through blood is analyzed. ⋯ Incidental or persistent infection with highly oncogenic types of HPV present in cervix paraepidermal epithelium cells is observed in approximately 30% of pregnant women. The presence of DNA HPV HR in trophoblast cells of HPV HR positive mothers is diagnosed rarely, in less than 7% of pregnant women. Human Papilloma Virus is present in the peripheral blood of pregnant women sporadically. None of the currently known risk factors of HPV infection may be correlated with DNA HPV HR presence in pregnant women.
