ABSTRACT
<p><b>OBJECTIVE</b>To understand the evolutionary relationship between the C4a evolutionary lineage of human enterovirus 71 (HEV71) strains circulating in mainland of China during 2008-2010 and 2008 Fuyang strains and study the prevalence and transmission patterns of 2008 Fuyang strains.</p><p><b>METHODS</b>Download all the complete VP1 ( > or = 891 bp) or approximate complete VP1 (> or = 876 bp) gene nucleotide sequences from GenBank of HEV71 strains circulating in Mainland of China during 2008-2010. And analyze the phylogenetic relationship between Fuyang strains and other provinces' strains using the MEGA software, version 5.0.</p><p><b>RESULTS</b>All of the HEV71 isolates circulating in Mainland of China during 2008-2010 were clustered into evolutionary lineage C4a except for eight strains grouped in the genotype A and one isolate belongs to evolutionary lineage C4b; the homology analysis showed there were 96.5%-100% identity between C4a viruses circulating in mainland China during 2008-2010 and 2008 Fuyang strains, and they were evolved from C4b viruses of 1998. The transmission chains of Fuyang strains were mainly transmitted in Guangdong, Jiangsu, Shanghai, Hunan, Shandong provinces.</p><p><b>CONCLUSION</b>The predominant viruses circulating in Mainland of China during 2008-2010 were evolutionary lineage C4a of human Enterovirus 71; Fuyang transmission chains mainly distributed in southern of China and the Central China around Anhui provinces.</p>
