When talking to practitioners, they will tell you that porcine reproductive and respiratory syndrome control feels like a moving target. Despite ever-growing investments aimed at preventing between-farm spread, PRRS incidence at the national scale remains relatively steady year-over-year. However, underneath this apparent steady-state, epidemic-like spread events occur every few years with the emergence of novel genetic variants (Figure 1). For instance, the Lineage 1A 1-7-4 virus (blue line) emerged in ~2014 and rapidly spread throughout the country.
