Wisconsin sport fish carry suite of new viruses

Researchers at the University of Wisconsin-Madison have detected a suite of new viruses in five species of Wisconsin sport fish. Although none pose a threat to human health, one is a type of coronavirus that’s usually associated with birds. It was found in healthy walleyes from Wisconsin lakes. The finding is part of a Wisconsin Sea Grant-funded study by Tony Goldberg, a professor in the Department of Pathobiological Sciences, of the natural diversity of viruses of fish in Wisconsin and is the first project of its kind in North America.
