Vulvar/vaginal human papillomavirus (HPV) infections may precede cervical infections, and certain low-risk types may display vaginal tropism. We evaluated whether incident infections in young women display site-specific preferences by HPV risk group or phylogenetic species. Although incident infections were more likely to be detected in the vulva/vagina than in the cervix (odds ratio, 4.38 [95%...

The incidence of human papillomavirus (HPV)-positive oropharyngeal cancers is higher and increasing more rapidly among men than women in the United States for unknown reasons. We compared the epidemiology of oral oncogenic HPV infection between men and women ages 14 to 69 years (N = 9,480) within the U.S. National Health and Nutritional Examination Surveys (NHANES) 2009-2012. HPV presence was d...

More than 100 different mucosal types of human papillomavirus (HPV) have been identified. The existence of different HPV types at different sites of the human body was recognized in the late 1960s. Human papillomavirus infection is considered the most common sexually transmitted disease and can infect the ocular surface, as well (1-3). The mode of transmission of HPV infection to the conjunctiv...

PURPOSE To investigate the relationship between human papillomavirus (HPV) infection and prostatitis-related symptoms. MATERIALS AND METHODS All young heterosexual patients with prostatitis-related symptoms attending the same Center from January 2005 to December 2010 were eligible for this case-control study. Sexually active asymptomatic men were considered as the control group. All subjects ...

Human papillomavirus (HPV) type-specific distribution was evaluated in genital samples collected from 654 women from the South of Italy undergoing voluntary screening and correlated with cyto-histological abnormalities. HPV DNA was detected in 45.9% of the samples, 41.7% of which had multiple infection and 89.0% had high-risk HPV infection. The prevalence of HPV infection and the rate of multip...

The common occurrence of multiple papillomavirus infections has been shown in several studies involving the human host. However, investigations with the aim of identifying mixed papillomavirus infections in cattle have been conducted only recently. In the current work we describe a co-infection with two different bovine papillomavirus (BPV) types that was identified in a bovine teat papilloma. ...

Determining the rate at which men develop genital warts after infection with alpha genus human papillomavirus (HPV) types will provide important information for the design of prevention strategies. We conducted a cohort study of 18-21-year-old men who underwent triannual genital examinations. The 24-month cumulative genital wart incidence was 57.9% (95% confidence interval [CI], 38.1%-79.1%) am...

BACKGROUND Prospective follow-up studies have recently suggested that persistent high-risk human papillomavirus (HPV) infections play a key role in the progression of CIN lesions and in the development of cervical cancer. However, data on type-specific persistence, viral integration, and the role of multiple infections are scanty. MATERIALS AND METHODS A cross-sectional/cohort study was condu...

Prospective studies of the persistence of human papillomavirus (HPV) variants are rare and typically small. We sequenced HPV-16 variants in longitudinal pairs of specimens from 86 women enrolled in the ASCUS-LSIL Triage Study. A change of variants was identified in 4 women (4.7% [95% confidence interval, 1.3%-11.5%]). Among women with intervening HPV results (n = 60), a variant switch occurred ...
