Prevalence of Human Papillomavirus (HPV) in the Oral Cavity of a Healthy Population in South-Eastern Poland

Human papillomavirus (HPV) is associated with both benign lesions and with neoplastic diseases, such as oropharyngeal cancer. Due to the increasing occurrence of these neoplasms on a global scale, it seems important to estimate the risk factors in the population. So far, data on the presence of oral HPV in the European population are scarce. Oral HPV was detected in 53 out of 461 healthy subjects (11.5%) in south-eastern Poland. Among the most common oncogenic types, HPV 16 was reported in four subjects (0.87%) and HPV 18 in three subjects (0.65%). Another high-risk type, HPV 45, was detected in nine subjects (1.95%). Low risk types (HPV 6, 11, 54) were detected in 25 cases, which constituted 5.4% of all tested samples. In adults and children, statistically more HPV positive cases have been reported in males than in females. A positive relationship was demonstrated between age and the amount of positive oral HPV. The presence of HPV was statistically more frequent in the population living in urban rather than in rural areas in all studied age groups (p < 0.05).
