Does HPV stay localized?
Localized love Several viruses, including hepatitis viruses and a herpesvirus, have been linked to cancers, but HPV is responsible for the highest number of virus-related malignancies. As a virus, however, it is highly unusual in that it can stick to a localized infection site, rather than spread throughout the body.
Can HPV be anywhere?
Human papilloma virus (HPV) causes common warts, the small, white, beige or brown skin growths that can appear almost anywhere on the body and on the moist mucous membranes near the mouth, anus and genitals. There are more than 150 different types of HPV, each with its own favorite skin surface to invade.
Is HPV localized or systemic?
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].
Where does the HPV virus live?
HPV lives in thin, flat cells called epithelial cells. These are found on the skin’s surface. They’re also found on the surface of the vagina, anus, vulva, cervix and head of the penis. They’re also found inside the mouth and throat.
How long does HPV survive outside the body and remain infectious?
Typically, the HPV types that cause genital warts survive just two to three hours outside the human body, he said, adding that if the virus is in a warm and humid environment, it can survive more than a day. If someone then makes skin contact with a contaminated surface, they could be infected, he said.
Where does HPV originate from?
HPV lesions are thought to arise from the proliferation of infected basal keratinocytes. Infection typically occurs when basal cells in the host are exposed to the infectious virus through a disturbed epithelial barrier as would occur during sexual intercourse or after minor skin abrasions.
