It is estimated that 60 percent of women will be infected with one or more of thousands related human papillomaviruses during their generative age. Among men, this number is smaller which can be explained that human papillomaviruses appearing in men is harder to prove. Some data from the United States show that close to 25 million people have HPV infections. Around 70 percent of Americans and 60 percent of British have never heard of HPV and don't know what does it mean.
HPV infection is the most common consequence of a sexual contact with an infected partner. This includes oral, vaginal or anal sex with someone who has HPV. Average period from the moment of infection of skin or mucous is three months, but this period is changeable and can last few weeks or few years, depending on individual immunological status. HPV can cause large spectre of HPV infections from common warts to cancer of genital tract.
Warts are soft, damply, pink or grey polyps which grow gradually. Warts appear most frequently in clusters like cauliflower and they hang on petiole, but they can be settled in level with a skin. Untill now, there's no satisfying methods for warts treatment, they continuously are coming back.
Genital warts and other lesions on, or near, patient genitals or anus are the most frequent types of HPV. But, HPV viruses can infect mucous of upper part of respiratory tracts. Viruses of genital and lower part of gastrointestinal system, depending on histopatological changes which are connected, are divided on low risk, middle and high HPV risk.
Low HPV risk doesn't cause precancerogenic changes on cervix, but it can cause genital warts. Because of absences of genital warts majority of population doesn't know that they are infected. Genital warts are the most frequently connected with HPV types 6 and 11. To low risk types belongs 42, 43 and 44 HPV types.
High HPV risk may cause precancerogenic changes on cervix if it is not treated. If a patient has high HPV it still don't mean that she has cervix cancer. It means that cells are attacked by pathological changes and need an urgent medical attention.
To prove HPV it is necessary for a patient to make urologic or gynaecologic examination. Urologist will took a swab from man's urethra and look out for warts presence. For women it is important to have regular pelvic exams and PAPA test which can help detect vaginal and cervical changes caused by genital warts or the early signs of cervical cancer. PAPA test may be negative - CIN1, it may show inflammation changes and causes of inflammation without changes on epital cells - CIN2, or it may show abnormal changing of epitel cells or carcinoma in situ - CIN3.
Some scientific researches show that chronical stress changes blood flow in cervix and affects its gland secretion which indicates and organic relation between the stress and skin and mucous changes. Body weakening along with bad nutrition, over drinking alcohol and smoking may provoke virus activity. A vaccine may prevent the most common types of HPV infection associated with either genital warts or cervical cancer, but there is no cure for the HPV itself. Partner changing, sexual activity with more then one partner, increases the risk of HPV. Also, sex with a person who had numerous partners before or is infected with HPV increases the risk, too. For women regular gynaecologic examination (annually) is the best way to prevent serious PAPA test results. ■
