It is clinically relevant because this condition is necessary for the development of epithelial cervical cancer, and it is also a factor closely associated with the occurrence of diverse tumours and various benign and malignant lesions of the head and neck area. The infective mechanism in most of these cases is associated with sexual intercourse, but there is recent scientific evidence suggesting that HPV infection may also be acquired by other routes of infection not necessarily linked to sexual contact. One of them is vertical transmission from mother to child, either during pregnancy or at the time of delivery.The aim of our research was to study maternal–foetal HPV transmission during childbirth in detail, establishing the rate of oropharyngeal neonatal HPV in vaginal deliveries. MethodThe presence and type of HPV viral DNA at the time of delivery in samples of maternal cervical secretions, amniotic fluid, venous cord blood samples and neonatal oropharynx in pregnant women (and their babies) were determined. ResultsThe rate of oropharyngeal neonatal HPV colonization in vaginal deliveries was 58.24%. ConclusionsThe maternal and neonatal HPV colonization mechanism is essentially, but not exclusively, transvaginal. ER -
