title: [Cervical infection epidemiology of human papillomavirus in Ushuaia, Argentina].
abstract: Genital infection with human papillomavirus (HPV) is decisive in the causation of cervical cancer. In order to evaluate the epidemiology of HPV infection in Ushuaia, Province of Tierra del Fuego, Argentina, 132 endocervical cytobrushes from preneoplastic and neoplastic cases and controls were studied. Detection and typing of the viral genome was performed by polymerase chain reaction, combined with a restriction fragment length polymorphism assay or hybridization. The overall prevalence of HPV infection was 41% in the population examined, with a frequency of 26% in the controls and 71% in the cases under study. The 14-24 age group showed the highest HPV prevalence. The most common viral types in the infected population were HPV 16 (23%), HPV 18 (11%), HPV 33 (8%) and HPV 35 (8%), while high risk viral types were detected in 30% of the samples, 16% of the controls and 60% of the cases. This study provides the first data on the predominant viral types in Ushuaia. Our results show lower levels of infection than in regions with a high incidence of cervical cancer, HPV 16 being the most prevalent viral type. This research may be useful for selecting a specific vaccine targeting the population examined.
