“…Since 2013, NADC30‐like PRRSV2 (lineage 1) variants have been prevalent in China (Brockmeier et al., 2012; Zhao et al., 2015; Zhou, Wang, et al., 2015). Since 2017, NADC34‐like PRRSV2 (lineage 1) has been detected and has the potential to be an endemic strain in China (van Geelen et al., 2018; Xu et al., 2020; Zhang et al., 2018). In addition, PRRSV1 isolates were also sporadically detected in China in recent years (Chen et al., 2011, 2017; Liu et al., 2017; Zhou, Liu, et al., 2015).…”
