CLAM LAKE, Wisconsin — Testing a black bear for COVID-19 doesn’t look much different from doing an at-home rapid test on yourself. 

Prepare the testing solution in a tube. Unwrap a swab. Insert into your nose and swirl it around for a few seconds; repeat on the other side. Put the swab into the tube of the testing solution and prepare it for shipment to a United States Department of Agriculture lab in Colorado.
