Human coxsackievirus A24 (CVA24) belongs to the species Enterovirus C, and variants of this virus frequently cause acute hemorrhagic conjunctivitis (AHC). The complete genome of the K282/YN/CHN/2013 strain, isolated from a healthy child in Yunnan, China, in 2013, is reported here for the first time. The strain showed 80.0 % and 79.9 % nucleotide sequence identity to CVA24 prototype strain Joseph and CVA24 variant prototype EH24, respectively. The K282/YN/CHN/2013 strain belongs to the CVA24 serotype. Twelve amino acid differences, most of which are in structural regions, were found between the CVA24 and CVA24v strains. In the whole-length genome sequence, only the structural region of K282/YN/CHN/2013 was similar to that of the CVA24 strains; the other genome regions were more similar to those of other members of the species Enterovirus C. Recombination analysis showed evidence of recombination with other viruses of the same species.
