Abstract: Infection with porcine reproductive and respiratory syndrome virus (PRRSV) in breeding herds causes significant changes in key production indicators (KPIs). Still, the swine industry lacks a clinical case definition for PRRSV outbreaks based on KPIs, hindering early detection and outbreak characterization. This study analyzed data from 75 outbreaks resulting in a definition based on KPI signals and diagnostic insights. An Excel tool for decision makers was created avoiding complex statistical methods. Using a 15-week moving average and a 2 SD threshold minimized false negatives and false positives, enabling proactive management and early outbreak detection through a reliable, accessible framework.
