A variety of human papillomavirus (HPV) types infect the anogenital mucosa, giving rise to lesions that differ in clinical appearance, histology, and risk of malignant progression. Certain high-risk types (HPVs 16, 18, 31, 33, 35 and 39) have a strong association with high-grade epithelial neoplasia and invasive carcinomas of the anogenital tract. Cancer appears to have a multifactorial etiolog...

Human papillomavirus (HPV), one of the most common sexually transmitted infections (STI) [1], has been known to have oncogenic potential for over five decades. Beginning with cervical cancer, research is now moving on to the implication of HPV infection in extragenital sites, such as the oral cavity, the oropharynx and the esophagus. The body of evidence implicating human papillomavirus as a ri...

In order to investigate whether previous findings of ubiquitous skin papillomavirus infection in Caucasians apply to populations from other parts of the world, skin swab samples from Bangladesh, Japan, Ethiopia and Zambia were analysed in parallel with Swedish samples. The prevalence of HPV DNA in the material from Bangladesh was 68 %, Japan 54 %, Ethiopia 52 %, Zambia 42 % and Sweden 70 %. A g...

Human papillomavirus vaccines have potential to reduce cervical cancer incidence and mortality; however, cultural and economic barriers may hinder success in developing countries. We assessed impact of a single vaccine campaign in Mali with use of mathematical modeling. Our model shows that decreases in the prevalence of Human papillomavirus infection are proportional to achieved vaccination co...

This year's Nobel Prize in Physiology or Medicine rewards the discoverers of two viruses that cause major afflictions of humankind. Identifying human papilloma virus (HPV) and human immunodeficiency virus (HIV) might now appear to have been simple, but the way forward was far from obvious at the time.

A wild-caught desert cottontail rabbit (Sylvilagus audubonii) from Colorado was observed to have large, pedunculated, dark cutaneous lesions on its abdomen and cylindrical masses on its mouth. Morphologically, the masses were consistent with previous reports of virally induced papillomas. Subsequent DNA analysis indicated widespread infection with cottontail rabbit papillomavirus.

PURPOSE The aim of this study was to evaluate the human papillomavirus genotypes and the frequency of multiple human papillomavirus infections, as well as to assess the association between human papillomavirus genotype, cyto-histopathological abnormalities and age range. METHODS A retrospective cross-sectional study was carried out between June 2010 and October 2013 in Salvador, Bahia, Brazil...
