The HPV genotypes were detected in 10542 HPV-positive with the Luminex Array. High-risk types include 20 oncogenic types and the other 5 types are classified intolow types. Single is when one type was detected as the sole type. Multiple is when >1 type is detected. Several samples had more than one HPV type detectable by PCR, thus the sum of the number of positive cases for each type of HPV exceeds the total number of samples in cases of multiple type infections
Group1/2A type (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 and 68), coinfection with HPV types of Group 2B and/or Group 3 allowed
Group 2B HPV type (26, 30, 53, 66, 67, 69, 70, 73 and 82), coinfection with HPV types of Group 3 allowed
Group 3 HPV type (6, 7, 9, 11, 40, 42, 43, 61, 74, 81, 83, 86, 87, 89, 90, 91 and 114)
