Chronic wasting disease test results

The average turnaround time from when the deer is brought to a sampling station to when the results are available is about 10 days.

Attention hunters: Due to a nationwide shortage of test kits used to test deer samples for CWD, there may be delays in notifying hunters of test results. Hunters who submitted samples on opening weekend of the 9-day gun deer season should be getting notification of test results as soon as Friday, December 8.

CWD testing history

Chronic wasting disease (CWD) was originally detected in Dane County in 2002. An extensive CWD surveillance program has been conducted in Wisconsin since then. Of Wisconsin's 72 counties 18 currently have CWD detected in the wild deer herd. Of the 18 counties 15 are within the area previously known as the CWD Management Zone (CWD-MZ), three counties of which include positives just outside of the border of the former zone (Grant, Waukesha and Juneau). Three counties with positives are outside of the former zone (Washburn, Portage and Adams).

The recent disease detections in areas such as Adams, Juneau and Portage counties as well as locational data collected within the former CWD-MZ, indicate the disease is spreading. The department welcomes public involvement in new areas of detection via the county-based citizen County Deer Advisory Councils (CDAC).

CWD results

You can search for CWD test results individually or view a summary. You will need a customer ID or CWD barcode to search for individual results. DNR adds tests results as they become available. DNR releases negative test results within a day after received. Positive test results are released as soon as DNR confirms the results and has contacted the hunter.

Interactive CWD mapping application

A CWD results mapping application is available for users to explore CWD results in all areas of the state as well as create maps. This application shows harvest locations of all deer tested for CWD including the positive test results.

Tips for CWD map

Summary

The CWD map allows you to add a layer of CWD sampled deer number ranges or CWD positive deer number ranges with additional layers. The deer numbers are cumulative. Deer results will be added to the map as soon as they are made public.

Basic tools

map layers Map layers – By clicking show layers you can choose what layers will show on the map. The legend will show the layers chosen as well as give the number ranges for the CWD results. In order to save a copy of the map you need to log in. Otherwise it is not necessary.



print Printing and saving – Clicking print/save PDF map allows you to create a PDF map. You will be able to add a title and notes and center the map as desired.

Features

measure Measurement tools – Distances or areas can be measured in different units such as miles or kilometers. One possible use could be how far a parcel of land is from a CWD positive.



find locations Find location – To find a specific township/range/section, county or city the find data tool can be used.



identify Identify – The identify tools can be used to obtain additional information on map features. If the identify tools are used to click on a CWD result range the number of samples collected, analyzed and positive will be displayed.



coordinate Coordinate tools – Can add points to specific latitude/longitude values or click a point on the map to get the latitude/longitude values. When adding coordinates the direction, N or W is required.

Editing

drawings Drawing – Text or shapes can be added to the map. To edit an item added to the map, click edit and then click on the item to be edited. Drawing can be erased one at a time or all at the same time.
