Introduction: Human papillomavirus (HPV) infection is mainly a problem of the female reproductive tract. It can occur in the oral cavity as well. Commonly HPV infections are subclinical, without any visible symptoms, and last no longer than 2 years. Usually the clinical manifestation of HPV infection is benign, but in some cases it can also promote malignant transformation. In the paper we have tried to estimate the prevalence of HPV detected in samples of oral leukoplakia (OLK), the most common premalignant lesions of the oral mucosa.
Aim: To review the current literature to estimate the prevalence of HPV (HPV DNA) detected in samples of oral leukoplakia.
Material And Methods: We searched PubMed/Medline, Scopus, and Cochrane Library databases for studies that examined the prevalence of HPV in leukoplakia with HPV DNA detection by polymerase chain reaction.
Results: HPV positive cases in OLK ranged from 0% to 100% in studies. The overall HPV prevalence in leukoplakia was 6.66%. The prevalence of HPV 16 positive cases was 2.95%. The high-risk HPV prevalence was 5.16%, when the low-risk HPV prevalence was 3.32%. When dysplasia is mentioned, HPV was detected in 19.56% of lesions with dysplasia, compared to 38.16% among non-dysplastic lesions.
Conclusions: Further studies should be extended also to include low-risk HPV and compare its prevalence with presence of dysplasia in leukoplakia. Besides, leukoplakia and other premalignant lesions can no longer be treated as one lesion.

Objective: This study aimed to uncover the patterns of Human papillomavirus (HPV) infection outcomes in women and assess the risk factors that may affect these outcomes.
Methods: A retrospective study was conducted on 608 women who tested positive for HPV-DNA during their initial visit to the outpatient department of Shenzhen Longgang Central Hospital from 2018 to 2023 and who had subsequent HPV-DNA testing as part of their post-visit monitoring. The monitoring intervals were every 6 months.

Objectives: This study aimed to determine the prevalence and genotyping of human papillomavirus (HPV) and to assess co-infection with Epstein-Barr virus (EBV) in oral cavity and oropharyngeal cancers (OC and OPC) specimens from patients at a tertiary care hospital in Northeastern Mexico.
Methods: Formalin-fixed and paraffin-embedded tumor specimens from 41 patients with OC and OPC were evaluated. HPV detection and genotyping were performed using the Ampliquality HPV-Type Express kit.

Introduction: High-grade cervical intraepithelial neoplasia (CIN) is a premalignant lesion of the cervix caused by persistent human papillomavirus (HPV) infection, which can lead to cervical cancer. Despite ongoing primary prevention efforts, considerable burden of illness remains. This study assessed the epidemiological, economic, and humanistic burden associated with high-grade CIN among adult women in Europe.

Background: Human Papillomavirus (HPV) is the most common sexually transmitted lower genital tract infection worldwide and the main etiological factor of cervical cancer (CC). Since 2006, vaccines have been implemented to reduce CC-related morbidity and mortality. This systematic review and meta-analysis aimed to evaluate the prevalence of cervical infections by non-vaccine high-risk HPV (HR-HPV) types in women vaccinated against types 16 and 18.

Objective: We aimed to assess the coverage of a Human Papillomavirus (HPV) screening program for each of the 32 federal states of Mexico, as well as the spatial patterns for HPV infections from 2013 to 2019.
Methods: We conducted an exploratory, ecological study on data from a national health program in Mexico during 2013-2019. Adjusted rates per 100,000 females aged 25-64 years were estimated and georeferenced at the national and state level to assess the coverage of the screening program and positive detections of HPV infections.
