    Abstract

    Human papillomaviruses from the β genus (βPV) are a possible cause of cutaneous squamous cell carcinoma (SCC). We assessed the extent to which βPV infections persisted long-term in a subtropical Australian community and whether βPV persistence is positively associated with actinic keratoses, precursor for SCC. Eyebrowhairs were collected from 171 participants of the community-based Nambour Skin Cancer Study in 1996 and 2003. Hair samples were tested for the presence of DNA from 25 different βPV types and assessed in relation to actinic keratosis presence in 2007. In 1996, a total of 413 βPV infections were found in 73% of participants, increasing to 490 infections among 85% in 2003. Of the total βPV infections detected, 211 (30%) were found to persist. Age was significantly associated with βPV persistence: those ages >60 years had 1.5-fold (95% confidence interval, 1.1-1.9) increased risk of type-specific viral persistence than those ages
