To investigate the human papilloma virus (HPV) infection status, main subtypes and age distribution characteristics of women in the Putuo area of Shanghai.
A total of 13,936 subjects were enrolled in this study. These subjects were 15–89 years old, with a mean age of 41.68. Real-time fluorescence quantitative polymerase chain reaction technology was used to detect 21 types of HPV.
A total of 2,500 subjects with HPV infections were detected in 13,936 cervical exfoliated cell specimens (total infection rate 17.9%). There were 15 people aged below 20,486 people aged 21-30,876 people aged 31-40,484 people aged 41–50, 338 people aged 51–60, and 301 people aged > 60. In total, 1,893 (75.7%) subjects had a single type of HPV infection, 424 (16.9%) had a double infection, and 183 had triple or more infections (7.4%). The top 6 subtypes of HPV infection in the Shanghai Putuo District were HPV 52 (3.81%), HPV 58 (2.46%), HPV 16 (2.43%), HPV 53 (2.30%), HPV 81 (1.74%) and HPV 39 (1.5%). The number of high-risk HPV infections was 1,978, and the total infection rate was 14.19%. The number of intermediate-risk HPV infections was 578, and the total infection rate was 4.15%. The number of low-risk HPV infections was 338, and the total infection rate was 2.43%.
The top 3 populations with HPV infection rates in the Putuo District, Shanghai, were ≤ 20 years old, older than 60, and 21–30 years old. The infection rate of HPV in cervical outpatient clinics was significantly higher than that of other departments. The 9-valent vaccine is recommended for HPV vaccination in this area.
