Characteristics of genotypes and prevalence of high-risk human papillomavirus in different economic development regions in China

A study with population-based published by He-Ling Bao and colleagues entitled “Prevalence of cervicovaginal human papillomavirus infection and genotypes in the pre-vaccine era in China: A nationwide population-based study” in this journal [1].We read with great interest. Yet, some points remain to be discussed, including whether the prevalence of high-risk human papillomavirus (HR-HPV) was different in level of economic development, geographic locations. A lot of previous studies have showed that disparities significantly in HPV prevalence exists across varying economic development and regions [2, 3, 4, 5].
