F G '• How is HPV spread?

• HPV is spread from direct s+in!to!s+in contact during sexual activity. includ

intercourse and oral sex• both opposite sex and same sex partners can spread the disease

• Is HPV a concern for you?

• 3I of cervical cancer is caused by strains 2J and 2K

• 3I of genital warts are caused by strains J and 22

• 'nyone can become infected with HPV

• 'bout 9I of all sexually active people become infected with the virus at s

their lifetime ! many people with HPV infections do not have any symptomscarry the virus and infect others

• 1here are no routine tests to detect HPV infection

• How is HPV prevented?

• 5ale and female condoms can reduce. but not eliminate the ris+ of HPV infdelaying sexual onset and limiting the number of sexual partners can help ris+ of getting HPV ! the HPV vaccine. called ardasilM. protects against fo

HPV# strains J. 22. 2J. and 2K ! the HPV vaccine is free only for females froupwards

Pathogenesis• HPV is a double!stranded /0' virus. which infects s>uamous epithelia. including th

mucosae of the upper respiratory and anogenital tracts

• HPV infection occurs at the basal epithelium"

• :nfection with one type of HPV does not prevent infection with another type

• HPV viruses are classiNed as either high!ris+ or low!ris+ types depending on thei

with the development of cancer

• 5ost HPV infections are asymptomatic and result in no clinical disease

• urveillance of HPV is complex due to the high proportion of asymptomatic infectio

variable presentation of the di4erent viral types and the long period between infec

HPV and Cancers• exually transmitted HPVs fall into two categories#

• Low!ris+ HPVs. which do not cause cancer but can cause s+in warts ,technically

condylomata acuminata- on or around the genitals or anus" Ror example. HPV tycause 3 percent of all genital warts"

• High!ris+ or oncogenic HPVs. which can cause cancer" 't least a doDen high!ris+ have been identiNed" 1wo of these. HPV types 2J and 2K. are responsible for theHPV!caused cancers"

• Cervical cancers are caused by HPV infections HPV types. 2J and 2K. responsible forpercent of all cases

• HPV also causes anal cancer. with about K9 percent of all cases caused by HPV!2J"

• HPV types 2J and 2K have also been found to cause close to half of vaginal. vulvar. acancers

• HPV infections have been found to cause cancer of the oropharynx. the base of the ttonsils"

• Other factors may increase the ris+ of developing cancer following a high!ris+ HPV in 1hese other factors include the following#

• mo+ing
