title: Prevalence of human papillomavirus and the correlation of HPV infection with cervical disease in Weihai, China.
abstract: OBJECTIVE
  This study investigates the human papillomavirus (HPV) infection rate in female genital tracts, as well as the HPV genotype distribution and HPV correlation with cervical disease in Weihai, Shandong Province, China.
  
  
  METHODS
  A random sample of 9,460 volunteers was simultaneously screened using gene chips and examined by ThinPrep liquid-based cytology test (TCT). Cervical biopsy samples were collected from women with positive HPV-DNA and abnormal TCT for pathological diagnosis.
  
  
  RESULTS
  The overall HPV prevalence was 6.93% (656 of 9,460). A total of 753 subjects were infected with HPV subtypes (including multiple HPV infections). Of those with infections, 688 were infected with high-risk (HR) types (91.37%), and 65 were infected with low-risk subtypes (8.63%). The single-infection rate was 63.1%.The prevalence rates of HPV in women aged 20 to 39 years and 40 to 59 years were 7.29% and 6.71%, respectively. The most common genotype was HPV16. The HR genotypes were associated with cervical diseases such as atypical squamous cells of undetermined significance (ASCUS) (37.9%), atypical squamous cells high grade (ASC-H) (42.5%), low grade squamous intraepithelial lesion (LSIL) (50%), and high grade squamous intraepithelial lesion HSIL (66.7%). Cervical biopsy results show that the HPV detection rate increased in the following biopsy samples: cervical intraepithelial neoplasia (CIN) I (74.11%), CIN II (84.31%), CIN III (90.32%), and squamous-cell carcinoma (SCC) (100%).
  
  
  CONCLUSIONS
  The HPV infection rate with associated cervical disease in Weihai is equal to those in foreign countries but is lower than the average rate in China. The prevalence of HPV was higher in young people. The most common HPV genotype was 16, followed by 52 and 58. HR HPV is the most probable infection factor for cervical diseases.
