Human Papillomaviruses HPV consists of a family of small, double-stranded DNA viruses that infect the epithelium. More than 200 distinct types have been identified; they are differentiated by their genomic sequence. Most HPV types infect the cutaneous epithelium and can cause common skin warts.
An HPV infection is caused by human papillomavirus, a DNA virus from the papillomavirus family. Over 170 types have been described. More than 40 types may be spread through sexual contact and infect the anus and genitals.
Given the fact that HPV infection is localized and not systemic, it is likely that these HPV types were self-inoculated (in the absence of oral sex) from the genital region to the oral region. In fact, HPV has been detected in the fingernails and oral cavity of women with vaginal HPV infection [31,34].Oct 9, 2019
In contrast with cervical HPV infection, BV is associated with major changes in the vaginal environment. Because women with BV possess a Lactobacillus-poor flora, their changes in the vaginal ecosystem may provide biological plausibility for an increased risk or reactivation of HPV infection.Jan 11, 2011
