Nationwide Prevalence and Genotype Distribution of High-Risk Human Papillomavirus Infection in China.

Nationwide hrHPV genotyping results from KingMed laboratories offer a baseline for measuring the future impact of large-scale HPV vaccination. High hrHPV infection rates in older (≥50 years) Chinese women likely reflect the limited extent of cervical screening in China. High rates of hrHPV infection and variable regional hrHPV genotype distribution may represent limiting factors for cost-effective implementation of hrHPV-based cervical screening in China.
