A fish-killing virus is creeping toward Lake Michigan.

The disease was recently discovered in the eastern Great Lakes.

Now, the state of Michigan says the virus has seeped into northern Lake
Huron, only about 20 miles from where it merges with Lake Michigan.

The disease doesn't pose any risk to humans. But fishing experts worry it
could be highly destructive to the $4.5 billion commercial and recreational

The disease has infected a wide range of species, including salmon,
whitefish and walleyes. It's been blamed for large kills of perch, musky and
freshwater drum, among other species
