The genomic distribution map of human papillomavirus in China

In this study, a total of 301,880 woman were recruited from 4 different regions of China. The overall prevalence of HPV was 18.01 %. The high-risk HPV infection rate was 79.14%, the low-risk HPV infection rate was 12.56 %, and the mixed HPV infection rate was 8.30%. The most common 4 HR HPV subtypes were HPV-52, 16, 58 and 53, which accounted for 20.49 %, 19.93 %, 14.54 % and 10.01 %. In LR HPV genotype, HPV-6 ranked the highest (28.17 %), followed by HPV-81 (9.09 %) and HPV-11 (3.78 %). HPV genotype subgroup analysis also showed that single-type infections had the highest prevalence rate (77.26 %) among HPV positive individuals. Among muti-infection genotype, double infection was the most common with frequencies of 76.04 %. This large report showed that the overall prevalence of HPV was high in China, whose distribution exhibits different patterns across different particular age and regions. Viral genotypes HPV 53, 6 were frequently detected in this population, which is worth of significant clinical attention.
