The first three people in Michigan under investigation for possible coronavirus have been cleared by the U.S. Centers for Disease Control and Prevention. The Michigan Department of Health and Human Services says two were in Washtenaw County and one was in Macomb County. A fourth possible case is now being tested by the CDC. Until recently, this virus had not been detected in animals or humans, and the source in Wuhan, China remains unknown. There are no suspected cases of coronavirus on the west side of Michigan.
