hu·man pap·il·lo·ma·vi·rus (HPV),

an icosahedral DNA virus, 55 nm in diameter, of the genus Papillomavirus, family Papovaviridae; certain types cause cutaneous and genital warts; other types are associated with severe cervical intraepithelial neoplasia and anogenital and laryngeal carcinomas. Over 70 types have been characterized on the basis of DNA relatedness.

HPV infection is the most common viral sexually transmitted disease. A single unprotected contact with an infected person carries a 60% risk of infection. The interval between exposure and clinical evidence of disease ranges from 3 weeks to 8 months. The annual incidence of genital HPV infection in the U.S. is estimated to be 3.5 million cases, with a prevalence of current infection of 20 million. More than one half of all sexually active women have been infected with one or more genital HPV types. About 15% have DNA evidence of current infection and 1% have genital warts. Most HPV infections are subclinical and transitory, the median duration of infection being about 8 months, with persistence rates of 30% at 1 year and 9% at 2 years. However, some types of HPV can induce genetic mutations in cervical epithelium that can culminate, after a latent period of 10-20 years, in the development of cancer. Carcinoma of the cervix is the most common malignancy in women under age 50. In the U.S., the incidence of cervical cancer is 8.3/100,000, with approximately 14,000 cases and 1,000 deaths annually. As many as 98% of all cancers of the cervix (most of which are squamous cell carcinomas) are believed to be induced by infection with HPV types 16, 18, 31, 33, and a few others. HPV typing in women with atypical squamous cells of undertermined significance (ASC-US) on cervical Papanicolaou smear helps to identify those in whom more intensive surveillance for premalignant change is warranted. Women with external genital warts (condylomata acuminata, which are usually due to HPV type 6 or 11) are not at increased risk of cervical cancer and do not need special surveillance if routine Papanicolaou smears are negative. Some 40% of HIV-positive women develop severe cervical dysplasia caused by HPV, which in many cases proceeds to fatal cancer with an aggressiveness not commonly seen among non-HIV-positive women. Diagnosis of HPV infection is based on visual inspection (including colposcopy with application of acetic acid to the cervix), Papanicolaou smear, and biopsy, with detection of viral DNA in tissue. Treatment options depend on the site and extent of involvement and include surgical excision, cryotherapy with liquid nitrogen, topical application of bichloracetic acid or trichloracetic acid, laser ablation, loop electrosurgical excision, and intralesional injection of interferon. External genital warts usually respond to topical treatment with podofilox gel or imiquimod (a cytokine-inducing agent that can be applied by the patient). Subclinical HPV infection, detectable only by Papanicolaou smear or other laboratory methods, may prove impossible to eradicate. The virus cannot be cultured, and there is no test to confirm cure. In limited trials, a vaccine has demonstrated efficacy in preventing both HPV-16 infection and HPV-related cervical intraepithelial neoplasia in women not previously exposed to the virus.

human papillomavirus

n. Abbr. HPV
Any of various genera of papillomaviruses that cause cutaneous and genital warts in humans, with some strains associated with cervical, anogenital, or laryngeal carcinomas.

A DNA virus that causes warts on acral parts which, in those with multiple sexual partners, may be premalignant, especially in those infected with types 16, 18, 31, 33 or 65 genotypes of HPV  have been described. A genotype is distinct if it has < 50% DNA sequence similarity or “homology” with its closest relative. HPV has been identified by in situ hybridisation in epithelial proliferations that are benign (e.g., condyloma acuminatum), or malignant (e.g., squamous cell carcinoma of the penis, anus, and uterine cervix) or of uncertain clinical behaviour (e.g., inverted papillomas of the nasopharynx).

human papillomavirus (HPV)

A member of the Papoviridae family that replicate in the nucleus of the host cell. HPV is the cause of common warts (HPV types 2, 4), flat warts (10), genital warts (6, 11), cervical intraepithelial neoplasia (6, 11, 16, 18, 31, 40, 42, 44), cervical cancer (mainly 16, 18), penile cancer and laryngeal cancer (mainly 16). The highest-risk HPV types are believed to be 16, 58, 31, 18, 56, 35, 33, 45, 52,39, 51 and 59.

Patient discussion about human papillomavirus

Q. hpv Can i get pregnant

A. You can get pregnant you just need to tell your doctor whats going on so he can keep an eye on the issue.

Q. Should I Vaccinate My Daughter Against HPV? I have a 12 year old daughter. Her School wants all the girls aged 12 and up to be vaccinated against HPV. A lot of Parents are against this vaccine. I want to know more about this vaccine and if I should vaccinate my daughter.

A. before you would like to go on with any vaccination, you should check out this very long list of links:

at the bottom you will also find links in english. vaccinations in general are very disputable/dubious and it is probably time that we learn about it.

Q. Is there a natural cure for hpv?

HPV facts | | The HPV virus is transmitted by close contact with other people and infects around 80% of the UK population.
The expert said in over 90 per cent of cases, the body clears off the HPV virus, while it persists in about 10 per cent, causing changes in the cervix that will lead to cancer later in life.
Yet, there is scientific evidence that, because the HPV virus is so common in men, a woman could choose to wait until she was married to engage in sex and still get it.
Though current high-risk HPV DNA testing methods generally provide very good sensitivity, specificity is limited (low positive predictive value) as they detect infection by the HPV virus in both their transient and persistent (transforming) states.
CyPep-1 rapidly and selectively targets HPV diseased cells, due to a negative charge on their cell membranes not found on healthy cells, rapidly killing the wart cells by disrupting the cell membrane and creating an immune response through the release of antigens which could lead to long-term protection.' CyPep-1 is an effective potential prescription treatment for warts that can potentially permanently eradicate the HPV virus. CyPep-1 has world-wide patent protection across the USA, Europe, Japan and China.
Eighty percent of women will be exposed to the HPV virus. Hence, we need to strengthen our immune system.
(8) Excision is not a complete cure, because persistence of the HPV virus in the cells of the larynx often causes recurrence of the lesion.
Stopping smoking, moderation in drinking, adopting a healthy lifestyle and being vaccinated against the HPV virus are all ways to help prevent mouth cancer.
VIN, differentiated type is not associated with the HPV virus and is frequently found in older women.
The HPV virus invades the epithelium through the basal cell layer and initiates viral cell production.
Young women can take a vaccine for the HPV virus, which doesn't combat cancer; it's a vaccine against a virus that has been proven to lead to a more serious cervical cancer."
Typing of the HPV virus associated with the above cervical lesions, using the techniques of DNA-DNA hybridisation with radiolabelled HPV probes, has implicated types 6, 11, 16, 18 and possibly 33.
