Analysis of human papillomavirus infection characteristics and genotypes in Shenyang area of Liaoning province

Objective To investigate the distribution of human papillomavirus (HPV) infection characteristics and genotypes in Shenyang area of Liaoning province. Methods HPV genes were detected in cervical exfoliated cells from 55, 548 patients by amplification and diversion hybridization. Results A total of 9, 566 patients were positive for HPV infection with a positive rate of 17.22%. Additionally, the positive rate of high risk HPV infection was 14.57% and the positive rate of single genotype HPV infection was 13.63%. Totally, 12, 360 HPV viruses were detected. Among them, 10, 879 HPV viruses were classified into high risk genotypes (10, 879 out of 12, 360, 88.02%). The genotypes in women with ages less than 20 were 16/11/6/51/58/52 genotypes; the susceptible HPV genotypes in other women were 16/58/52/53/39/51/81 genotypes. Conclusions HPV infections in Shenyang are mainly infections with high risk viruses and single infection. The infection rate and genotype distribution of HPV are different in different age groups. More suitable HPV vaccine prophylaxis can be taken according to the epidemic characteristics of HPV in this area. Key words: Human papillomavirus; Genotype; Infection characteristics
