Abstract:

Objective To investigate the infection status and subtype distribution of human papillomavirus (HPV) in Shaanxi Xianyang. Methods A total of 7 708 cervical cell specimens were analyzed by polymerase chain reaction (PCR)- reverse spot hybridization technology for HPV genotyping. Results A total of 2 477 patients with HPV infection were determined in 7 708 women. The total infection rate was 32.14%(2 477/7 708),and the infection rate of high-risk subtypes was 23.96%(1 847/7 708),including multiple high-risk subtypes. The most common high-risk subtypes were 16,52,58,51,56 and 66 in the 18 high-risk subtypes. The infection rate of single subtype in patients with HPV infection was 27.58% (2 126/7 708). The infection rate of single high-risk subtype was 19.94%(1 537/7 708). The common single high-risk subtypes were 16,52,58,51,33 and 39. The infection rate of multiple subtype was 4.55%(351/7 708). The infection rate of multiple high-risk subtype was 4.53% (349/7 708). The infection rate of 31-40 years old group was the highest (10.20%). The common high-risk subtypes were 16,52,58,51,56 and 33 in 31-40 years old group. There was different subtype distribution in other age groups. Conclusions The infection rate of HPV in Shaanxi Xianyang is high,and the common high-risk subtypes are 16,52,58,51,56 and 66. HPV subtype distribution of different ages has a certain difference. The women of 30-50 years old should be monitored for HPV.
