Dr. Wineland says this outbreak is much different than the one seven years ago because of the way the virus is spreading.
"We're seeing point source introductions continue from the wild birds, we had hoped to see that diminish as temperatures warmed and the bird migrations moved on. And we haven't seen that diminishing happening yet," said Dr. Wineland.
The announcement comes on the same day the state confirmed its first bird flu outbreak at a commercial poultry farm in Muskegon County.
According to the U.S. Department of Agriculture, over 35,000 turkeys will have to be culled at the Muskegon facility.
"It's hard to have a historical context, when the last time we had highly pathogenic avian influenza in Michigan, we didn't see it in any poultry. I think we had it only in wild birds," said Dr. Wineland.
So far this year, Michigan has responded to 12 cases of bird flu in non-commercial backyard flocks from nine different counties across both the Upper and Lower Peninsulas.
