83 of Minnesota's 87 counties now have high or substantial COVID-19 transmission

Less than a month ago, just 14 counties fell into those categories.

Just over three weeks ago, when federal health officials recommended everyone in COVID hotspots wear a mask while in public indoor spaces, just 14 Minnesota counties reached that face-covering threshold.

That number is now up to 83.

All but four of the state's 87 counties have what the Centers for Disease Control and Prevention (CDC) considers "substantial" or "high" transmission, according to Friday morning's data. Under CDC guidance, every person — whether vaccinated or not — should wear a face covering while in public, indoor spaces in these areas.

What's more, the vast majority of these counties have the most severe "high" level of transmission. (That's the red in the map to the right.)

The continued increases in COVID-19 infections, hospitalizations and positivity rate have prompted many governmental units, businesses, schools and venues to reimplement mask mandates or add new vaccination requirements. On Friday, the state said it had recorded 1,708 new cases and 10 newly reported deaths, with a positivity rate of 5.57%.

The four Minnesota counties with only "moderate" transmission are: Big Stone, Kittson, Koochiching and Red Lake. Below you'll find lists of counties with high and substantial transmission, organized alphabetically.
