Fig. 4From: Molecular characteristics of the VP1 region of enterovirus 71 strains in ChinaSubgenotype percentages of EV71 for every year in China. In this study, 12 genotypes were detected among 3712 strains. The B4 genotype was the predominant strain between 1999 and 2003 and C3 genotypes from 2004 to 2005; the C4a subgenotype was the most common epidemic strain from 2006 to 2018Back to article page
