HPV16 infection status in HIV-infected individuals over time. Oral rinses were collected from subjects at visits 1 (baseline), 2 (6-months), 3 (12-months), 4 (18-months) and 5 (24-months). Tonsillar samples were collected at visits 1, 3 and 5. Oral rinse samples and tonsillar cytology samples were evaluated for the presence of HPV16. Figure 2A shows individuals who were present for all three visits and had at least one detectable tonsillar HPV16 infection. Shaded circles are tonsillar samples which are HPV16-positive. Unshaded circles are HPV16-negative tonsillar samples. In figure 2B, individuals who had an oral HPV16 infection detected during at least one visit are depicted. Shaded circles are oral rinse samples which are HPV16-positive. Open circles indicate HPV16-negative oral rinse samples. Horizontal bar indicates a concomitant tonsillar HPV16 infection. The absence of circle signifies that an individuals did not provide oral rinse sample, was lost to follow-up or sample was unevaluable at a specific visit.
