HPV infection of anus and perianal skin is common, even without anal intercourse. The incidence of anal HPV infection in straight men is 12-24% and in women 27-50%. HPV is detected in 60% of gay and in 90% of HIV+, even without anal intercourse.<\/p>\n\n\n\n
The perianal area can be infected with direct intercourse, vaginal discharges, washing, fingers and sexual toys. Viral infection in lesbians is not unusual. Only skin cells in a 5-6 cm from anal verge are infected. The epithelium (lining) of intestine which is located deeper is not infected by HPV virus. The virus is usually cleared from anus after 1-3 years of infection. Multiple partners, absence of condom prophylaxis, douching, smoking, anal intercourse and corticosteroid creams are adverse factors that obstruct viral clearance. Condoms are not a completely safe method of prophylaxis.<\/p>\n\n\n\n
HPV infection is usually asymptomatic. There are about 40 HPV subtypes that infect anogenital area. These subtypes can infect mouth and tonsils. The benign subtypes make papilloma-like warts. Other subtypes are the cause of intraanal neoplasia that can progress to anal cancer. These dysplastic lesions can be detected with anal cytology and subsequent high resolution anoscopy.<\/p>\n\n\n\n
