West Nile virus is back in Michigan.
The state's first case of the year has been confirmed in a bird found in Muskegon County.
Health experts are not surprised that West Nile has resurfaced in the state.
The Michigan Department of Community Health says cases of the mosquito-borne virus can be expected in birds, horses, other animals and humans in 2006.
But officials say the extent of the virus can't be predicted.
Health experts say people should try to avoid being bitten by mosquitoes.
There were 62 reported human cases of West Nile in Michigan last year. There were four deaths.
