HPV Prevention Week October 1-7

  • More than 75% of sexually active men and women will be infected with the Human Papilloma Virus (HPV) at some point in their lives.
  • HPV is a sexually transmitted infection (STI) that can cause genital warts and six different types of cancer — Oropharyngeal, Penile, Anal, Vaginal, Cervical and Vulvar — but it is preventable.
  • The HPV vaccine is very effective for school-aged children and people of all ages.  Those with previous exposure to HPV or a history of HPV-related diseases still benefit from HPV immunization.
  • HPV is not a female-only virus. Recent data shows that more than 3500 Canadians — 1/3 of them males — are diagnosed with HPV-related cancers annually.
  • Human papilloma virus is a group of more than 100 different types, with many high-risk types that pose an increased risk for oncogenicity.
  • There are over 100 HPV types, of which at least 40 types infect the genital tract. Although many individuals clear an HPV infection over time, persistent infection with HPV can result in malignancy.
  • Almost all incidences of cervical cancer are preceded by a persistent HPV infection with a high-risk HPV type.
  • HPV is also associated with 80-90% of anal cancers and up to 72% of oropharyngeal cancers among other cancers of the reproductive tract, such as the vulvar, vagina, and penis 1,2.
  • Human papilloma virus (HPV) is the most common viral infection of the anogenital tract, and can cause the development of pre-cancerous and cancerous lesions in both females and males.
  • HPV is linked to the development of cervical cancer which is the 4th leading cause of death in all females 3,4,5.
  • The Internal Agency for Research on Cancer (IARC) has classified 12 types of HPV as known carcinogens: HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59)6. Of these, HPV types 16 and 18 account for 70% of cervical cancer cases world wide 7,8,9 and HPV types 16, 18, 31, 33, 45, 52, and 58 account for 90% of cervical cancer cases.
  • Accordingly, HPV2 and HPV4 vaccines offer protection for up to 70% of cervical cancer cases, while the HPV9 vaccine offers protection for up to 90% of all cervical cancer cases.

The HPV vaccine is now covered by the Saskatchewan Government for girls and boys in Grade 6.
