Infectious Disease | Recent data published in Clinical Infectious Diseases suggest that anal HPV infections among women are common but typically clear within 3 years.
However, persistence of anal HPV infections is associated with sexual behaviors, including anal intercourse and anal finger sex, and may suggest that the anus is being reinfected, according to Anna-Barbara Moscicki, MD, of the division of adolescent medicine at the University of California, San Francisco.
“It may be that, eventually, the immune system is overwhelmed and the infection is not cleared,” Moscicki told Infectious Disease News. “Persistence is important since it is necessary for anal cancer to occur. In the United States, anal cancer is more common in women than in men, and this is likely due to anal sex behaviors.”
