NADC30-like porcine reproductive and respiratory syndrome virus (PRRSV) has widely spread in China and become locally dominant virus strain in some provinces. Although they are not pathogenic as highly pathogenic PRRSV (HP-RRRSV) that outbreaks since 2006, NADC30-like PRRSVs distinguished themselves by high incidence of recombination with other virus strains which lead to change of virulence. The outbreaks of NADC30-like PRRSV in the vaccinated pig herds suggested that current commercial PRRSV vaccines cannot provide complete protection to the infection. In this review, we have described in detail the current situation of NADC30 PRRSV including epidemiology, genomic characterization, pathogenicity, and efficacy of current commercial vaccines in China.

Porcine Reproductive and Respiratory Syndrome (PRRS) is caused by Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), which is characterized by sow reproductive disorder and piglet respiratory syndrome. The complex pathogenesis of PPRS includes antibody-dependent enhancement, immune suppression and persistent infection in the body and viral genetic diversity. In order to have a better understanding of the occurrence and prevalence of porcine reproductive and respiratory syndrome in China. The review of PRRS etiology, epidemiology, pathogenesis, genetic variation, diagnosis and control technology and other aspects of the progress were carried out.
