Mitchell to Decide on Whether to Extend Mask Mandate Last November, Mitchell city council members voted to institute a mask mandate to help curb the spread of the COVID-19 virus. Today, they plan to vote again to consider the possibility of extending the mandate even longer. At this time, the mask mandate in Mitchell applies to people inside buildings within city limits and requires them to wear a mask if social distancing is not possible. Dakota News Now is reporting, five of the Mitchell City Council members must vote in favor of the mandate today for it to be extended.
