HPV specificity and multiple infections and association with cervical cytology in Chongqing, China: a cross-sectional study.

Background: It is important to assess the relationship between specific HPV genotype or multiple infection and cervical cytology. The protection provided by the HPV vaccine is type-specific, and the epidemiology feature of coinfections needs to be investigated. The aim is to provide baseline information for developing HPV vaccination and management of HPV-positive populations in the region.

Epidemiologic characteristics of high-risk HPV and the correlation between multiple infections and cervical lesions.

Methods: The current study involved population-based sample of 20,059 women who underwent cervical screening for 15 HR-HPV genotypes with ThinPrep cytologic test (TCT) results. The correlation between multiple HPV genotype infections and cervical lesions was also determined.
