Overview
Genital HPV infection is very common, with estimates suggesting that more than 50% of women will become infected with one or more of the sexually transmitted HPV types at some point during adulthood.[1]
Epidemiology
Cutaneous warts
- Widespread in general population
- Incidence of common warts is more than plantar or flat warts
Genital warts
- Anogenital HPV is the most common sexually transmitted infection in the USA [2]
- In USA, the prevalence of anogenital HPV infection is estimated to be 79 million with incidence of 14 million new cases each year [2]
- Worldwide, 90% of genital warts is caused by the HPV 6 and 11[3]
- Prevalence of genital warts is 1% in USA as compared to 10% in Scandinavian countries
- In USA, the incidence of genital warts has slightly increased in the year 2013

†Data from CDC
HPV associated cancers
- In USA, the incidence of HPV associated cancer is 38,793 each year (data 2008-2012)[4]
- Cervical cancer
- Oropharyngeal cancer
- Incidence of oropharyngeal cancer associated with HPV is showing an increasing trend in USA(23297039)(21969503)
- 70% of oropharyngeal cancers are associated with HPV[4]
- Anal cancer
- In USA, the incidence of anal cancer has increased in the last three decades(23297039)((19293308)(19156144)(23042932)
- There is increased incidence among HIV positive individuals and incidence has not shown a decline after the advent of antiretroviral therapy.(7062503)
- Recurrent respiratory papillomatosis
- Rare with rates of about 2 cases per 100,000 children in the United States[5]
- Common in children born to females having active genital warts at the time of vaginal delivery
Demographics
Following demographic factors may affect the incidence and prevalence of HPV infection:
Age
Cutaneous warts
- More common in children aged 12-16 yrs of age[6] (2599836)
- 10% of children and 3.5% of adults are affected, worldwide
Genital warts
- Incidence of genital HPV infection increases at the age when individuals begin to engage in sexual activity.[7][8]
- Highest incidence of genital warts is seen in females aged 20-24 yrs and males aged 25-29 yrs of age[9] (CDC)
- Prevalence of cervical HPV in females may decline after age 30(12571255)
HPV associated cancer
- Incidence is more common in younger age group(sexually active)(18334711)(2196503)(18798277)(22641955)
Recurrent respiratory papillomatosis
- Increased incidence is seen in children as compared to adults(18496162)(23013073)

†Data from CDC
Gender
Genital warts
Prevalence per 1000 person-years Among participants in private health plans aged 10–39 years by sex, age group, and year, 2003–2010 is shown in the graph below:
†Data from CDC
HPV associated cancers
- Out of total 38,793 HPV-associated cancers that occur in the United States each year, 23,000 occur among women, and about 15,793 among men[4]
- Three fold increased prevalence of HPV associated anal and oropharyngeal cancer in men as compared to women.
- Increased incidence of oropharngeal and anal cancer among men who have sex with men (MSM)[10](22282321 JAMA)(22706220)(24625808)(25291584)
- Worldwide, the point prevalence of HPV in females is 10%, with highest prevalence among african females(17597569)
Race
- There may be increased incidence of high risk HPV infections in african american females as compared to caucasians[8][11]
