Analysis of human papillomavirus infection status and genotype distribution in women in Huzhou, China / 中华实验和临床病毒学杂志

ABSTRACT

Objective@#To observe the infection status and the distribution of the gene subtypes of human papillomavirus (HPV) in Huzhou.@*Methods@#Cervical exfoliated cells were collected from the women who attended the physical examination and the cervical HPV examination from June 2017 to December 2017 in Huzhou Maternal and Child Health-Care hospital. A total of 2 830 women were tested for 21 HPV genotypes (including HPV-16, 18, 31, 59, 66, 53, 33, 58, 45, 56, 52, 35, 68, 51, 39, 82, 26, 73, 6, 11, 81), using real-time polymerase chain reaction (RT-PCR), investigated the infection status and subtype distribution.@*Results@#Among the 2 830 women, 269 were positive for HPV, the total infection rate was 9.51% (269/2 830). The infection rate of single gene and double gene was 86.99% (234/269) and 11.90% (32/269), respectively. The infection rate of high-risk subtypes was 9.11% among the detected women (258/2 830), accounting for 83.77% of HPV gene detections (258/308). The HPV-58, 16, 52 were the most commonly found gene subtypes among the high-risk HPV. The rate of HPV infection and high-risk subtypes of HPV infection in women was the highest in the 56-60 year old group, and the lowest in the 31-35 year old group. In different age groups, the difference in high-risk HPV infection rate was statistically significant, the total infection rate had no statistical significance.@*Conclusions@#In Huzhou area, the HPV infection rate of women found through normal physical examination was 9.51%, the high risk type was 58, 16 and 52, and the 56-60 year old group was the high incidence group. This study provides the HPV infection status and HPV gene subtype distribution characteristics in women in Huzhou, which has important guiding value for the vaccine development and application, and for prevention of HPV infection.
