Gardasil 6 is an HPV vaccine aimed at preventing cervical cancers and genital warts. Gardasil is designed to prevent infection with HPV types 16, 18, 6, and 11. HPV types 16 and 18 currently cause about 70% of cervical cancer cases, and also cause some vulvar, vaginal, penile and anal cancers. HPV types 6 and 11 are responsible for 90% of documented cases of genital warts.

Gardasil 9, approved in 2014 protects against HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58.

HPV vaccines do not currently protect against the virus strains responsible for plantar warts (verrucas).

The virus is relatively hardy and immune to many common disinfectants. Exposure to 90% ethanol for at least 1 minute, 2% glutaraldehyde, 30% Savlon, and/or 1% sodium hypochlorite can disinfect the pathogen.

The virus is resistant to drying and heat, but killed by and ultraviolet radiation.

Studies show a link between HPV infection and penile and anal cancers. Sexually transmitted HPVs are found in a large percentage of anal cancers. Moreover, the risk for anal cancer is 17 to 31 times higher among gay and bisexual men than among heterosexual men

- though one survey did not find a difference between the HPV infection rate of men who had sex with men versus those who had sex only with women.

Anal Pap smear screening for anal cancer might benefit some subpopulations of men or women engaging in anal sex. No consensus exists, though, that such screening is beneficial, or who should get an anal Pap smear.

Worldwide, HPV is estimated to infect about 12% of women at any given time. HPV infection is the most frequently sexually transmitted disease in the world.

The exact cause of VIN is unknown. Studies are being done to determine the cause of VIN. The following factors have been associated with VIN:

- HPV (Human Papilloma Virus)

- HSV-2 (Herpes simplex Virus - Type 2)

- Smoking

- Immunosuppression

- Chronic vulvar irritation

- Conditions such as Lichen Sclerosus

Vaccinating girls with HPV vaccine before their initial sexual contact has been claimed to reduce incidence of VIN.

Normally found in children or young adults, a common cause of conjunctival squamous cell papilloma is during childbirth, when the mother passes the virus to her child.

At the start of each wrestling meet, trained referees examine the skin of all wrestlers before any participation. During this examination, male wrestlers are to wear shorts; female wrestlers are only permitted to wear shorts and a sports bra. Open wounds and infectious skin conditions that cannot be adequately protected are considered grounds for disqualification from both practice and competition. This essentially means that the skin condition has been deemed as non-infectious and adequately medicated, covered with a tight wrapping and proper ointment. In addition, the wrestler must have developed no new lesions in the 72 hours before the examination. Wrestlers who are undergoing treatment for a communicable skin disease at the time of the meet or tournament shall provide written documentation to that effect from a physician. This documentation should include the wrestler’s diagnosis, culture results (if possible), date and time therapy began, and the exact names of medication for treatment. These measures aren’t always successful, and the infection is sometimes spread regardless.

Bowenoid papulosis is a cutaneous condition characterized by the presence of pigmented verrucous papules on the body of the penis. They are associated with human papillomavirus, the causative agent of genital warts. The lesions have a typical dysplastic histology and are generally considered benign, although a small percentage will develop malignant characteristics.

It is considered as a pre-malignant condition. Other terms used to describe the condition are: Erythroplasia of Queyrat, Squamous cell carcinoma in situ and Bowen’s disease. The term "Bowenoid papulosis" was coined in 1977 by Kopf and Bart and is named after dermatologist John Templeton Bowen.

The term “intraepithelial neoplasia” defines a premalignant intraepithelial change.

On the vulva it is termed VIN (vulvar or vulval intraepithelial neoplasia); on the penis, PIN (penile intraepithelial neoplasia); and on or around the anus, AIN (anal intraepithelial neoplasia). The terminology has been very confusing and it is now recommended that the terms Bowen’s disease, erythroplasia of Queyrat, and bowenoid papulosis should not be used for lesions in the anogenital area. However, dermatologists still recognize a distinct clinical variant, bowenoid papulosis, characterized by discrete papules in a younger age group and a tendency for spontaneous regression. Additionally, some authorities believe that erythroplasia of Queyrat and Bowen’s disease remain useful terms in men.

According to the NCAA Wrestling Rules and Interpretations, used by all high schools in the United States: "Infection control measures, or measures that seek to prevent the spread of disease, should be utilized to reduce the risks of disease transmission. Efforts should be made to improve wrestler hygiene practices, to utilize recommended procedures for cleaning and disinfection of surfaces, and to handle blood and other bodily fluids appropriately. Suggested measures include: promotion of hand hygiene practices; educating athletes not to pick, squeeze, or scratch skin lesions; encouraging athletes to shower after activity; educating athletes not to share protective gear, towels, razors or water bottles; ensuring recommended procedures for cleaning and disinfection of wrestling mats, all athletic equipment, locker rooms, and whirlpool tubs are closely followed; and verifying clean up of blood and other potentially infectious materials." More ways of prevention include wearing long sleeve shirts and sweatpants to limit

the amount of skin to skin contact. A wrestler should also not share their

equipment with other teammates and should regularly check their skin for any lesions or other signs of outbreaks. Body wipes are also common to see Coaches must also enforce the disinfecting and sanitary cleansing of the wrestling mats and other practice areas. This can greatly limit the spread of skin infections that can infect an individual indirectly.

One high school wrestling coach from Southern California described his methods of prevention using three simple procedures. “Keep the mats [clean]…you’ve got to bleach and mop them every day before practice. Along the same lines, gear should also be washed regularly, especially headgear…Most importantly, the wrestlers need to shower immediately after practices. If one kid doesn’t, and he gets [infected], it can spread to everyone else on the team within a week. I’ve had it happen before, to the point where some schools won’t allow any of our guys to wrestle in a meet. When this happens, it’s a huge blow to the school’s record and reputation. In the future, we are less likely to be invited to exclusive tournaments in the coming year.”

Squamous cell papilloma of the mouth or throat is generally diagnosed in people between the ages of 30 and 50, and is normally found on the inside of the cheek, on the tongue, or inside of lips. Oral papillomas are usually painless, and not treated unless they interfere with eating or are causing pain. They do not generally mutate to cancerous growths, nor do they normally grow or spread. Oral papillomas are most usually a result of the infection with types HPV-6 and HPV-11.

Immunoperoxidase stains have identified antigens of the human papillomavirus (HPV) types 6 and 11 in approximately 50% of cases of squamous cell papilloma.

Myrmecia is one of the three types of warts that occurs on the skin on the hands and feet (palmoplantar). It is induced by human papilloma virus type 1 (HPV1). They occur on the palms of the hands, soles of the feet, and on the sides of the fingers and toes. The histology is abundant eosinophilic inclusion bodies associated with HPV1 E4 gene products. It was studied as far back as 42 B.C. - 37 A.D. by Aulus Cornelius Celsus.

A papilloma (plural papillomas or papillomata) ("" + "") is a benign epithelial tumor growing exophytically (outwardly projecting) in nipple-like and often finger-like fronds. In this context refers to the projection created by the tumor, not a tumor on an already existing papilla (such as the nipple).

When used without context, it frequently refers to infections (squamous cell papilloma) caused by human papillomavirus (HPV), such as warts. Human papillomavirus infection is a major cause of cervical cancer, although most HPV infections do not cause cancer. There are, however, a number of other conditions that cause papilloma, as well as many cases in which there is no known cause.

Herpes gladiatorum is one of the most infectious of herpes-caused diseases, and is transmissible by skin-to-skin contact. The disease was first described in the 1960s in the "New England Journal of Medicine". It is caused by contagious infection with human herpes simplex virus type 1 (HSV-1), which more commonly causes oral herpes (cold sores). Another strain, HSV-2 usually causes genital herpes, although the strains are very similar and either can cause herpes in any location.

While the disease is commonly passed through normal human contact, it is strongly associated with contact sports—outbreaks in sporting clubs being relatively common.

Other names for the disease are herpes rugbiorum or "scrumpox" (after rugby football), "wrestler's herpes" or "mat pox" (after wrestling). In one of the largest outbreaks ever among high-school wrestlers at a four-week intensive training camp, HSV was identified in 60 of 175 wrestlers. Lesions were on the head in 73 percent of the wrestlers, the extremities in 42 percent, and the trunk in 28 percent. Physical symptoms sometimes recur in the skin. Previous adolescent HSV-1 seroconversion would preclude most herpes gladiatorum, but being that stress and trauma are recognized triggers, such a person would be likely to infect others.

Management for an individual with chronic mucocutaneous candidiasis consists of the following(relapse occurs once treatment is ceased, in many cases):

Herpes gladiatorum is only caused by the herpes simplex virus. Shingles, also manifesting as skin rashes with blisters, is caused by a different virus, herpes zoster. Other agents may cause skin infections, for example ringworm is primarily due to the fungal dermatophyte, "T. tonsurans". Impetigo, cellulitis, folliculitis and carbuncles are usually due to "Staphylococcus aureus" or Beta-hemolytic streptococcus bacteria. These less common forms can be potentially more serious. Anti-viral treatments will not have an effect in non-viral cases. Bacterial infections must be treated with antibiotics and fungal infections with anti-fungal medication.

Chronic mucocutaneous candidiasis can be diagnosed in an affected individual via the following methods/tests:

People with HPV-mediated oropharyngeal cancer tend to have higher survival rates. The prognosis for people with oropharyngeal cancer depends on the age and health of the person and the stage of the disease. It is important for people with oropharyngeal cancer to have follow-up exams for the rest of their lives, as cancer can occur in nearby areas. In addition, it is important to eliminate risk factors such as smoking and drinking alcohol, which increase the risk for second cancers.

The risk factors that can increase the risk of developing oropharyngeal cancer are:

- Smoking and chewing tobacco

- Heavy alcohol use

- A diet low in fruits and vegetables

- Chewing betel quid, a stimulant commonly used in parts of Asia

- Mucosal infection with human papilloma virus (HPV) (HPV-mediated oropharyngeal cancer)

- HPV infection

- Plummer-Vinson syndrome

- Poor nutrition

- Asbestos exposure

Certain genetic changes including: P53 mutation and CDKN2A (p16) mutations.

High-risk lesions:

- Erythroplakia

- Speckled erythroplakia

- Chronic hyperplastic candidiasis

Medium-risk lesions:

- Oral submucosal fibrosis

- Syphilitic glossitis

- Sideropenic dysphagia (or Paterson-Kelly-Brown syndrome)

Low-risk lesions:

- Oral lichen planus

- Discoid lupus erythematosus

- Discoid keratosis congenita

Any age may be affected although it is most common in children aged five to fifteen years. By the time adulthood is reached about half the population will have become immune following infection at some time in their past. Outbreaks can arise especially in nursery schools, preschools, and elementary schools. Infection is an occupational risk for school and day-care personnel. There is no vaccine available for human parvovirus B19, though attempts have been made to develop one.

Immunodeficiency or immunosuppression can be caused by:

- Malnutrition

- Fatigue

- Recurrent infections

- Immunosuppressing agents for organ transplant recipients

- Advanced HIV infection

- Chemotherapy for cancer

- Genetic predisposition

- Skin damage

- Antibiotic treatment leading to disruption of the physiological microbiome, thus allowing some microorganisms to outcompete others and become pathogenic (e.g. disruption of intestinal flora may lead to "Clostridium difficile" infection

- Medical procedures

- Pregnancy

- Ageing

- Leukopenia (i.e. neutropenia and lymphocytopenia)

The lack of or the disruption of normal vaginal flora allows the proliferation of opportunistic microorganisms and will cause the opportunistic infection - bacterial vaginosis.

Since opportunistic infections can cause severe disease, much emphasis is placed on measures to prevent infection. Such a strategy usually includes restoration of the immune system as soon as possible, avoiding exposures to infectious agents, and using antimicrobial medications ("prophylactic medications") directed against specific infections.

Causes of Bowen's disease include solar damage, arsenic, immunosuppression (including AIDS), viral infection (human papillomavirus or HPV), chronic skin injury, and other dermatoses.

Heck's disease (also known as focal or multifocal epithelial hyperplasia) is an asymptomatic, benign neoplastic condition characterized by multiple white to pinkish papules that occur diffusely in the oral cavity. Can present with slightly pale, smooth or roughened surface morphology. It is caused by the human papilloma virus types 13 and 32. It exhibits surface cells with vacuolated cytoplasm around irregular, pyknotic nuclei and occasional cells with mitosis-like changes within otherwise mature and well-differentiated epithelium. A distinguishing histologic feature is elongated rete ridges resembling Bronze Age axe with mitosoid bodies present. It was first identified in the Aboriginal population.

Over time, they will spontaneously regress without treatment. Possible treatment may be excisional biopsy for lesions of functional or aesthetic concern.
