Human papillomavirus (HPV) is a well-established carcinogenic agent. This study aimed to assess prevalence and persistence rate of genital HPV infection in sexually transmitted infections (STIs) patients and healthy subjects. The risk factors influencing the persistence of genital HPV infection were also investigated. The samples were collected with the ThinPrep liquid-based cytology system. Among the HPV-positive patients, those consenting were retested after 12 months. Overall, 145/292 subjects proved HPV positive with a higher prevalence (51%) in STI than in healthy population (43%). The persistence of genital HPV infection was statistically associated with female gender, HR-HPV infection, smoking, and Ureaplasma parvum infection.

The most common STD that triggers cervical cancer is the human papillomavirus. More than 20 types of human papillomavirus (HPV) can induce uterine cervical cancer. Almost all women acquire genital HPV infection soon after their first intercourse, with most of them clearing the virus within 3 years.

Human papillomaviruses (HPV) from the genus beta have been implicated in the development of cutaneous squamous cell cancer in and organ transplant patients. In contrast to alpha-high-risk HPV, which cause ano-genital and oropharyngeal cancers, beta-HPV replication is not well understood. The beta-HPV49 transcriptome was analyzed by RNA sequencing using stable keratinocyte cell lines maintaining high levels of extrachromosomally replicating E8- genomes, which can be established due to a lack of the viral E8^E2 repressor protein.

Background: Human papillomavirus (HPV) is a common infection of the anogenital tract. Although most infections clear, persistent infections with oncogenic types can predispose to cancer. While the natural history of anogenital HPV infection in cisgendered women is relatively well understood, there are significant knowledge gaps regarding HPV prevalence and clinical implications of genital HPV infection in transgender women (TGW) with neovagina(s).

Human papillomavirus (HPV) infections drive one in 20 new cancer cases, exerting a particularly high burden on women. Most anogenital HPV infections are cleared in less than two years, but the underlying mechanisms that favour persistence in around 10% of women remain largely unknown. Notwithstanding, it is precisely this information that is crucial for improving treatment, screening, and vaccination strategies.

Background: Persistent infection with high-risk human papillomavirus (HPV) is a significant risk factor for cervical cancer. HPV typing and cytology are conducted in women of appropriate age to assess the risk of cervical lesions and to guide the need for further diagnostic procedures such as colposcopy, cervical biopsy, or treatment. This article explores methods to predict the risks of high-grade precancerous cervical lesions based on high-risk HPV typing.
