Epidemiology of Mucosal Human Papillomavirus Infection and Associated Diseases
Bibliographic record
Abstract
This article describes the epidemiology of mucosal human papillomavirs (HPV) in adults and children, its mode of transmission and its associated diseases. Over 40 genotypes of HPV infect the epithelial lining of the anogenital tract and other mucosal areas of the body. HPV is the most common sexually transmitted infection globally, with high prevalences found in both females and males. The predominant route of transmission is via sexual contact, although mother-to-child transmission is also possible. HPV infection may exist asymptomatically or may induce the formation of benign or malignant tumours in the genital, oral or conjunctival mucosa. Although most infections clear spontaneously, those that persist result in substantial morbidity and invoke high costs associated with the treatment of clinically relevant lesions. Some 13-18 mucosal HPV types are considered to have high oncogenic potential. HPV is recognized unequivocally as the main causal factor for cervical cancer, and is further responsible for a substantial proportion of many other anogenital neoplasms and head and neck cancers. Infections with HPV types that have low oncogenic risk, such as HPV-6 and 11, are associated with benign lesions of the anogenital areas known as condylomata acuminata (genital warts), oral papillomas, conjunctival papillomas, as well as low-grade squamous intra-epithelial lesions of the cervix. Perinatally acquired HPV can also cause recurrent respiratory papillomatosis in infants and young children. The implementation of HPV vaccination therefore has the potential to prevent a substantial proportion of HPV-related disease in the future.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
