This cross-sectional survey assessed the determinants of human papillomavirus (HPV) infections among 2080 women who participated in cervical cancer screening. HPVs were typed by restriction and sequencing analyses. The prevalence of HPV was 7.3% (4.2% for high-risk, 1.9% for low-risk, and 2.1% for unknown-risk types). High-risk HPV prevalence decreased with age, whereas low- and unknown-risk HP...

Human papillomavirus is one of the most common sexually transmitted diseases worldwide. The natural history of oral HPV infection is unclear, and its risk factors have not been explored. Immunocompromised individuals, as exemplified by HIV patients, are at high risk for HPV-related diseases. The mean of this study is to determine the prevalence of HPV in the oral tract of HIV-1-positive male su...

BACKGROUND In developed countries, the incidence of cervical cancer has remained stable in HIV+ women but the prevalence and multiplicity of high-risk HPV (hrHPV) infection, a necessary cause of cervical cancer, appears different comparing HIV+ to HIV- women. Little is known about HIV and HPV co-infection in Africa. METHODS We enrolled women presenting at our cervical cancer screening program...

To understand viral interactions and the cross-reactivity of natural or vaccine-induced responses, we investigated whether multiple human papillomavirus (HPV) infections, particularly certain combinations of types, have the tendency to cluster together. Cervical cell samples were collected from women in the framework of the IARC HPV Prevalence Surveys. Women with a cytology diagnosis of high-gr...

This study reports six HR-HPV types' infection prevalence discriminated by species and multiple infection in unvaccinated Colombian female adolescents, as well as some factors modulating the risk of infection. HPV DNA for six high-risk viral types was identified in cervical samples taken from 2,134 12-19 year-old females using conventional generic and type-specific PCR. Binomial logistical regr...

The unkeratinized epithelium of the inner human foreskin is thought to be more susceptible to human papillomavirus (HPV) entry than the rest of the penis. However, studies exploring a potential association between male circumcision and HPV infection have produced conflicting results. The present review stratifies the evidence based on methods of sampling and detection of HPV infection, HPV type...

PURPOSE Acquisition of human papillomavirus (HPV) in women occurs predominantly through vaginal sex. However, HPV has been detected in girls reporting no previous sex. We aimed to determine incidence and risk factors for HPV acquisition in girls who report no previous sex in Tanzania, a country with high HPV prevalence and cervical cancer incidence. METHODS We followed 503 adolescent girls ag...

The presence of more than one human papillomavirus (HPV) genotype may influence the duration of prevalently detected infections. This analysis included 1,646 infections detected at enrollment in 980 women from the Guanacaste, Costa Rica, cohort who were actively followed up every 6-12 months for up to 8 years. We categorized HPV infections as single or multiple types. Persistence of infections ...

The prevalence of Human Papillomavirus (HPV) in the general population of northern Taiwan is described. A total of 343 consecutive cervical swabs from women visiting the medical center for routine gynecologic care were included. Cervical cell cytology was examined by the Papanicolaou (Pap) test, and a PCR-based hybridization gene chip analysis was used to identify HPV genotypes. The HPV prevale...

Cancer of the uterine cervix (CC) is the second most common cancer in women worldwide. In Colombia, CC is the second most frequent cancer among the entire women population and the first among women aged between 15 and 44 years, with an estimated incidence of 24.9 cases/100,000 inhabitants. The main risk factor is infection with one or more high-risk human papillomavirus (HPV) types. The aim of ...
