LANSING, Mich. (AP) — Officials say three cases of canine flu that hit the Midwest earlier this year have been confirmed in Michigan.

The Michigan Department of Agriculture and Rural Development said one case was reported in Macomb County and two cases in Kent County. Department spokeswoman Jennifer Holton says the notification from a lab was made to the state last week.

Holton tells The Detroit News that veterinarians aren’t required to report the virus.

Experts blame the epidemic on a strain called H3N2 that is seen in Asia and leaves pets feeling lousy for about two weeks. The virus gets passed through the air when dogs sneeze or by people when germs jump on hands or clothing, where they can live for hours.

Canine flu doesn’t sicken people.
