Warts on hands are caused by an infection of the human papillomavirus (HPV). There are more than 100 different strains of HPV, according to the U.S. Food & Drug Administration. Different strains ...
HPV is a group of more than 200 related viruses, which are designated by a number for each virus type. [10] Some HPV types, such as HPV5, may establish infections that persist for the lifetime of the individual without ever manifesting any clinical symptoms. HPV types 1 and 2 can cause common warts in some infected individuals. [18]
[1] [3] The virus is believed to infect the host through the entrance of a skin wound. [1] A number of types exist, including plantar warts, "filiform warts", and genital warts. [3] Genital warts are often sexually transmitted. [5] Without treatment, most types of warts resolve in months to years. [1]
Butcher's wart is a wart on the hands of butchers. [1] They tend to occur in multiple numbers. [2] These warts are generally larger than common warts. [3] It is typically associated with HPV2, 4 and 7; up to 50% by HPV7. [1] [3] It occurs when hands have had prolonged contact with moist meat. [3] Following treatment, they typically recur. [3]
Papillomaviridae is a family of non-enveloped DNA viruses whose members are known as papillomaviruses. [1] Several hundred species of papillomaviruses, traditionally referred to as "types", [2] have been identified infecting all carefully inspected mammals, [2] but also other vertebrates such as birds, snakes, turtles and fish.
A papilloma (plural papillomas or papillomata) (papillo-+ -oma) is a benign epithelial tumor [1] growing exophytically (outwardly projecting) in nipple-like and often finger-like fronds. In this context, papilla refers to the projection created by the tumor, not a tumor on an already existing papilla (such as the nipple).
Human papillomavirus (HPV)-associated oropharyngeal cancer awareness and prevention is a vital concept from a public and community health perspective. HPV is the sexually transmitted virus that is known to be the cause of genital warts. There are currently more than 100 different strains of HPV, half of which can cause genital infections. [1]
US incidence of HPV infection has increased between 1975 and 2006. [29] About 80% of those infected are between the ages of 17 and 33. [29] Although treatments can remove warts, they do not remove the HPV, so warts can recur after treatment (about 50–73% of the time [33]). Warts can also spontaneously regress (with or without treatment). [29]
