Persistence of baseline-detected and newly detected carcinogenic genotypes of human papillomavirus (HPV) infection by age group. The proportion of carcinogenic type-specific infections still persisting among those tested at each time point was calculated for prevalent and newly detected infections by age groups. They were color coded as follows: red, prevalent infections among women 18–25 years old; gray, prevalent infections among women 26–33 years old; yellow–green, prevalent infections among women 34–41 years old; black with stars, prevalent infections among women aged 42 years or older; dark blue, new infections among women 18–25 years old; magenta, new infections among women 26–33 years old; dark green, new infections among women 34–41 years old; light blue, new infections among women aged 42 years or older. The percentages of carcinogenic HPV infections that persisted 6 years after enrollment among passively followed prevalent infections were 5.1% among women 18–25 years old, 14.4% among women 26–33 years old, 12.2% among women 34–41 years old, and 18.2% among women aged 42 years or older.
