Porcine reproductive and respiratory syndrome virus (PRRSV) was considered as an important pathogen, which caused huge economic losses for the world swine industry annually. Until now, according to antigenic and genetic characteristics, two genotypes were identified, European (EU genotype, or type 1) genotype and North American genotype (NA genotype, or type 2), respectively. In China, both of them co-existed in swine herds, and even some novel viral strains emerged in the lastest years. The aim of the review was to describe genetic diversity of PRRSV based on non-structural protein 2 (Nsp2) in China, which could help us better understand molecular
