HPV infections return as some women age

NEW YORK — Signs of the cancer-causing human papilloma virus in women near or at menopause may be a reawakened dormant infection, suggesting a risk for women who came of age in the ‘‘sexual revolution’’ in the 1960s and ’70s.

About 77 percent of the infections were detected in women who reported five or more sexual partners in their lifetime, according to a study in the Journal of Infectious Diseases. The findings released Thursday suggest that reactivation of the sexually transmitted virus may increase around age 50 and be responsible for more later-life infections than new ones, researchers said.
