Flow Chart of hrHPV Screening of the FRIDA Study Population. Women 30 to 64 years of age living within our target health district were invited by healthcare personnel. This study reports the results from the first 31,629 women who volunteered to participate in the Tlaxcala cervical cancer screening program. Four-hundred and eighty-three women were excluded, leaving 30,829 who had hrHPV results available, in the current analysis. Of those 30,829 women, 3,401 women were positive for hrHPV. Among those 3,401 women, 13.6 % were positive for HPV16, 5.9 % for HPV18 and 1.1 % for both HPV16 and HPV18 coinfection. These three categories indicate positivity independent of the presence of other hrHPV types. The last category of other high risk HPV types include women who tested positive for other hrHPV types (31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68), but neither HPV16 nor HPV18
