  1. VIRUSES HUMAN PAPILLOMA VIRUS

  2. NAME OF VIRUS • Virus classification-Group:Group I (dsDNA) Order:Unranked • Family:Papillomaviridae • Genera-Alphapapillomavirus; Betapapillomavirus; Gammapapillomavirus; Mupapillomavirus; Nupapillomavirus

  3. TYPE OF VIRUS • There are over 100 types of HPV • Most instances of HPV infection are asymptomatic (no clinical manifestations). • Cervical infection can result in cervical changes which can be detected by pap testing or biopsy. • There are more than 40 HPV types that can infect the genital areas of men and women, including the skin of the penis, vulva (area outside the vagina), and anus, and the linings of the vagina, cervix, and rectum. Causing genital warts in men and women

  4. TYPE OF VIRUS (cont’d) • Other HPV types can cause cervical cancer and other less common cancers, such as cancers of the vulva, vagina, anus, and penis. • The types of HPV that can cause genital warts are not the same as the types that can cause cancer.

  5. WHAT DOES THE VIRUS AFFECT? • In men, for the most part, the virus can cause some unnoticeable skin changes, the most common skin change that does occur is genital warts appearing around the anus or on the penis, scrotum (testicles), groin or thighs. The warts start off from small, flaky patches to pronounced, raised growths. • In some men "high-risk" types of HPV can cause certain types of cancer, such as cancer of the penis or anus. • The warts on this man’s body are an extreme case caused by HPV.

  6. WHAT DOES THE VIRUS AFFECT? • In women, again, genital warts are sign or symptom of HPV and show up in cauliflower shaped clusters in the genital area. • Cervical Cancer is also caused by the HP virus and does not show any signs or symptoms until the advanced stages.

  7. IS IT A DISEASE? IF SO WHY? HOW DOES IT WORK? • 1 Virus, More Than 1 Disease • Cervical canceris caused by certain types of human papillomavirus (HPV). Other types of the virus can cause genital warts. • Some HPV types can cause warts while others may cause a subclinical infection resulting in precancerous lesions. All HPVs are transmitted by skin-to-skin contact and/or by fomites. (A fomite is any inanimate object or substance capable of carrying infectious organisms (such as germs or parasites) and hence transferring them from one individual to another.) • A group of about 30-40 HPVs is typically transmitted through sexual contact and infect the an ogenital region. Some sexually transmitted HPVs may cause genital warts. However, other HPV types which may infect the genitals do not cause any noticeable signs of infection

  8. HOW MANY DOES IT AFFECT? WHAT ARE THE SYMPTOMS? • According to the CDC, among sexually active females (i.e., 57% of females aged 14--19 years and 97% of those aged 20--59 years), the prevalence of HPV infection was highest for those in the youngest age groups (i.e., approximately 40% in those aged 14--19 years and 50% in those aged 20--24 years). Prevalence declined substantially after age 24 years. • Infection with the human papillomavirus (HPV) usually does not cause any symptoms and does not always produce visible genital warts. • The HPV virus lives in mucous membranes, such as those in the genital area, or on the skin. If genital warts show up, it's an indication of HPV infection. Genital warts take on many different appearances. They can be raised, flat, pink, or flesh-colored. They can even be shaped like cauliflower.

  9. WHAT ARE THE SYMPTOMS? (cont’d) • When symptoms do develop, they usually occur 2 to 3 months after infection. However, symptoms have been known to develop from 3 weeks to many years after infection. • Symptoms that may occur with genital warts include: • Irritation. • Itching. • Bleeding.

  10. WHAT ARE THE SYMPTOMS? (cont’d) • Genital warts may be large, or they may be too small to be seen with the naked eye. They may appear individually or in groups. • In women and men, warts may appear in the groin, on and around the genitals, in the urethra, or in the rectum or anus. • In women: • Genital warts may appear on the vulva, vagina, or cervix. • Women are often unaware of warts inside the vagina or on the cervix until a health professional finds them. • In men: • Genital warts may occur on the outside of the penis and scrotum. • Men are often unaware they have genital warts, even when they can be seen, until the warts are identified by a health professional.

  11. WHAT CAN BE DONE ABOUT THIS VIRUS? • The HP Viruses requires several treatments before the symptoms become less active • After treatment the virus may remain in nearby skin and remain inactive for months even years, and in some cases warts never return • It is recommended that patients applied therapies such as crytotherapy, podophyllin resin, interferon, or surgery
