Wisconsin CWD Surveillance Dashboard
An interactive choropleth mapping 25 years of Chronic Wasting Disease surveillance data across Wisconsin's 72 counties. Watch CWD radiate outward from the Dane/Iowa County epicenter beginning in 2001, track county-level prevalence rates, and explore the relationship between disease spread and deer harvest trends.
All data sourced from Wisconsin DNR CWD surveillance reports (1999-2025). 351,800+ deer tested, 16,300+ CWD positives. Dashboard is a work in progress.
