* * UPDATE * * The Genesee County Health Department is reporting that incorrect information was provided to Michigan.gov earlier today and positive coronavirus diagnoses were erroneously reported in Genesee and Isabella Counties. The number of cases in Michigan has been corrected to 334.

However, news reports now indicate that General Motors is confirming that a worker at the Flint Assembly plant has tested positive for the virus. GM says the employee has not been inside the plant during the last 14 days, so its workforce will not be forced to self-quarantine.
