An additional 507 new COVID-19 cases and four deaths were reported Wednesday by the Minnesota Health Department.
Confirmed case counts have generally been increasing since mid-June, when testing was finding about 300 to 400 cases each day.
So far the pandemic has claimed 1,552 lives and 47,961 people have been sickened.
With Minnesota now reporting a seven-day average daily case count of about 600 new infections, Gov. Tim Walz is expected to announce Wednesday afternoon a mandate that face masks must be worn in stores, public buildings and other indoor gathering spots.
Public health officials have long recommended the use of face masks to curb the spread of the new coronavirus.
"Data has shown that in areas and countries with mask mandates, it does increase the usage rate of masks," Minnesota Health Commissioner Jan Malcolm said Monday.
"The mandate would serve to just reinforce the expectation that it is the norm to wear a mask in most circumstances," she said.
Minnesota's increase in confirmed COVID-19 cases was sparked in part by an increase in infections among young adults.
