All HPV types from single to multiple infections were computed individually, for% calculation the denominator is represented by the total number of infections (single or multiple) by type. From alfa-9 HPV group: 16, 31, 33, 35, 52 and 58. From alfa-7 HPV group: 18, 39 and 45. ST: single type, MT: multiple type, hr-HPV: high risk HPV, lr-HPV: low-risk HPV.
