Figure 1

Chronic wasting disease positivity rates in farmed cervids, South Korea, 2001–2024. A) All farmed cervids; B) red deer; C) elk; D) sika deer. Each dot represents a single farm. Positivity rates were calculated as no. animals testing positive/no. animals tested on each farm. Dots reflect the farm’s cervid population because all farmed cervids were culled and tested on farms with positive cases. For species-specific analyses, each cervid species on each farm was assessed separately.
