  https://www.mayoclinic.org/diseases-conditions/plantar-warts/symptoms-causes/syc-20352691

  Plantar warts are caused by the same type of virus that causes warts on your hands and fingers. But, because of their location, they can be painful. […] Plantar warts are caused by HPV. This virus enters through tiny cuts or breaks on the bottom of the feet. […] Plantar warts are caused by an infection with HPV in the outer layer of skin on the soles of the feet. The warts develop when the virus enters through tiny cuts, breaks or weak spots on the bottom of the foot. […] HPV is very common, and more than 100 kinds of the virus exist. But only a few of them cause warts on the feet. Other types of HPV are more likely to cause warts on other areas of your skin or on mucous membranes. […] The HPV strains that cause plantar warts aren’t highly contagious. So the virus isn’t easily spread by direct contact from one person to another. But it thrives in warm, moist places, so you might get the virus by walking barefoot around swimming pools or locker rooms. If the virus spreads from the first site of infection, more warts may grow.

  Once in contact with a host, HPV gains entry to the basal epithelial layer, where actively dividing stem cells are located. […] After infection, if the virus is not cleared, the host basal keratinocyte is stimulated to divide and replicate viral DNA via HPV E1 and E2 proteins. […] Once infection occurs, 3 outcomes are possible: clearance of the infection with resultant immunity to that particular HPV type, latent infection, or clinically manifested infection as a plantar wart. […] The induction of cellular replication throughout the process of viral genome amplification leads to the hyperkeratinized papule that constitutes a plantar wart.

[…] Calloused or broken skin on the bottom of your foot. […] A family member has plantar warts. […] Weak immune system. […] The Human Papilloma (HP) virus loves warm, moist areas, so sweaty feet increase the likelihood of getting a plantar wart. […] Having broken and damaged skin on the bottom of your feet will allow the HP virus to enter the skin and allow a plantar wart to start. […] Families share showers, so if a family member has plantar wart, they can spread them on the shower floor without the others being aware that there is a problem. […] Viral warts affect children and teens more than adults because their immune systems have not developed the antibodies to fight strains of HP virus that cause warts.

  Two of the most significant risk factors for developing plantar warts are (1) having a preexistent wart and (2) having close contact with someone who has a preexistent wart. […] Plantar warts have a very high viral load, which increases the rate of viral shedding and the likelihood of contaminating adjacent body surfaces, inanimate communal surfaces, or close contacts. […] Walking barefoot also increases the likelihood of contacting HPV, especially if one walks barefoot in an area where others have walked barefoot, such as pool decks or communal showers. […] Immunocompromised patients have higher rates of plantar warts, along with increased severity and duration of the lesions.

  Plantar warts begin when a sneaky virus called human papillomavirus (HPV) decides to hitch a ride. HPV invades the skin through tiny cuts or abrasions, usually on the soles of your feet. […] They spread through direct contact, so places like communal showers, pools, and gym floors are hotbeds for transmission. […] If your immune system isn’t at its A-game—whether due to illness, stress, or other factors—you’re more vulnerable. […] Younger people are more prone to warts because their immune systems haven’t built up resistance to HPV. […] Spending time in locker rooms and around communal showers? It’s a prime spot for picking up the virus.

  Once in contact with a host, HPV gains entry to the basal epithelial layer, where actively dividing stem cells are located. […] After infection, if the virus is not cleared, the host basal keratinocyte is stimulated to divide and replicate viral DNA via HPV E1 and E2 proteins. […] Once infection occurs, 3 outcomes are possible: clearance of the infection with resultant immunity to that particular HPV type, latent infection, or clinically manifested infection as a plantar wart. […] The induction of cellular replication throughout the process of viral genome amplification leads to the hyperkeratinized papule that constitutes a plantar wart. […] Plantar warts tend to develop at areas of increased pressure on the sole of the foot, including the heel and metatarsal heads. […] Such pressure points are regions of increased microtrauma to the epidermal barrier, which increases the likelihood of HPV invasion.

  Plantar warts occur when the human papillomavirus (HPV) enters the body through cuts or breaks in the skin and causes growths to erupt on the soles of the feet. […] HPV is spread by direct and indirect contact from an infected host. To avoid transmission, it is important to avoid direct contact with infected surfaces. Examples of risky surfaces include communal changing rooms and shower floors and benches. Additionally, avoid sharing shoes and socks. Contact with anyone with HPV can increase your risk of spreading the infection. […] There are two distinct types of plantar warts. The first are solitary warts that appear on their own. The second are mosaic warts which appear as group clusters on the foot. Mosaic warts can be more difficult to treat.

  Warts are due to infection by the human papillomavirus (HPV), a double-stranded DNA virus. There are more than 150 known HPV types, only some of which infect the skin, giving rise to a variety of clinical presentations. […] The most common HPV types infecting the skin are types 1, 2, 3, 4, 10, 27, 29, and 57. […] HPV is spread by direct skin-to-skin contact or autoinoculation; if a wart is scratched or picked, a wart may develop under the fingernail (subungual wart) or virus may be spread to another area of skin. […] Plantar warts (verruca plantaris) include tender inwardly growing myrmecia on the sole caused by HPV 1, and clusters of superficial less painful mosaic warts due to HPV 2. […] Myrmecial warts are typically tender with lateral and direct pressure, are surrounded by yellow hyperkeratotic callus-like skin showing accentuated skin markings, but with discontinuation of the skin lines through the actual wart. […] Plantar epidermoid cysts are associated with HPV 60 infection of the eccrine ducts.

  Warts are caused by an infection of the skin by human papillomavirus (HPV), which is the most common viral infection of the skin. […] The HPV types 57, 27, and 1a account for most plantar warts. The virus gains access to the skin through direct contact. […] It is presumed that inoculation of the skin occurs in places likely to be contaminated by others with plantar warts, like communal showers. […] Once infected by HPV, spontaneous resolution seems to depend on the development of immune lymphocytes that destroy the virus-infected cells. […] HPV infections are ubiquitous infections, with at least one-half of adults infected during their lifetime. […] There are at least 120 different types of human papillomavirus (HPV), and certain types tend to infect specific anatomical areas, like the plantar surface of the foot. […] Risk factors for the development of plantar warts include use of public showers, skin trauma, and weakened immune system because of certain medications used or illness.

  Plantar warts are caused by cutaneous infection with the human papillomavirus (HPV). There are numerous types of HPV which manifest in different ways. Plantar warts are generally caused by HPV-1, 4, 27 and 57 […] HPV is transmitted by skin contact or contact with surfaces touched by other people with the virus. HPV can be present for weeks or years before the appearance of a wart, and persists for life, even after the wart has resolved. This may lead to recurrence at the same site, e.g. if a person who is carrying the virus becomes immunosuppressed; plantar warts are very prevalent in organ transplant recipients. […] In rare cases (and particularly in people who are immunosuppressed), warts of prolonged duration have been reported to undergo malignant transformation to squamous cell carcinoma or plantar verrucous carcinoma.
