A highly pathogenic strain of porcine reproductive and respiratory syndrome virus (PRRSV), characterized by a discontinuous
30-amino-acid deletion in its Nsp2-coding region, has been emerging in China since 2006. Here, we report the complete genomic
sequence of two novel Chinese virulent PRRSV variants with additional NSP2-gene deletions, which will help us understand the
molecular and evolutionary characteristics of PRRSV in Asia.
