Abstract:
Objective:To investigate the epidemiology of human papillomavirus (HPV) infection and gene subtypes among women in Qingdao form 2015 to 2019, so as to provide scientific support for the prevention and treatment of HPV related cervical cancer in Qingdao.Methods:A total of 26396 female cervical exfoliated cell specimens were collected at the Affiliated Hospital of Qingdao University from January 2015 to October 2019, then 17 high-risk HPV genotypes and 6 low-risk HPV genotypes were detected by PCR and reverse dot blot in vitro, and prevalence and year, genotype and age distribution were analyzed.Results:The total prevalence of HPV was 18.17%. The prevalence of single infection, double infection and multiple infection were 13.41%, 3.40% and 1.35% respectively. The infection rate of 7 high-risk subtypes (HPV52, 16, 58, 53, 56, 51, 68) and 3 low-risk subtypes (HPV81, 42, 43) exceeded 1%. The HPV prevalence of different age groups was significantly different and the prevalence showed a bimodal pattern among different age groups. There were two peaks in the ≤25 years group and 46-50 years group, which were 23.61% and 19.63% respectively. There was no significant difference in genotype distribution among different age groups.Conclusions:The cervical HPV infection rate of women in Qingdao is at a medium level, and single infection is the main pattern in different genotypes and age groups. In addition to the vaccine coverage subtypes, the prevalence of other subtypes such as HPV 53, 56, 51 and 68 in this region is also high. Therefore, regular HPV screening is still needed after vaccination to find out HPV genotypes which are not covered by the vaccine. It is suggested that the government optimize the HPV vaccine coverage genotypes to prevent the occurrence of HPV infection associated with cervical cancer.
