The infection rates of the HPV31 and HPV35 types are extremely low among Chinese women. HPV31 and HPV35 infection rates were approximately 7.0% and 5.5%, respectively, either alone or in combination with other types [8, 9, 10, 11]. Between 2013 and 2023, a single HPV31 infection was detected in 150 women (median age 42.0 years; range 20–69 years) and a single HPV35 infection was detected in 133 women (median age 44.0 years; range 21–71 years) were selected in this study.
