  • Minnesota uses the case definition agreed upon by the Council of State and Territorial Epidemiologists to define a Minnesota COVID-19 case: CSTE: Update to the standardized surveillance case definition and national notification for 2019 novel coronavirus disease (COVID-19) (PDF).
    • Cases meeting the confirmed or probable case criteria are included in Minnesota data unless otherwise specified.
  • Data are for cases that were tested and returned positive. At-home test results are not reported to MDH and are not included in this data.
  • All data are preliminary and may change as more information is received.
    The shaded bar at the end of graphs indicates a lag period where data may be incomplete.
  • Population estimates are obtained from the 2010 Census Bureau Population Estimates Program (PEP) and the 2019 American Community Survey (ACS) 5-year estimates for the state of Minnesota available at United States Census Bureau: Explore Census Data.

  • Case data by date is represented by the date of specimen collection unless otherwise specified.
  • All data are preliminary, and reports require verification before counting as a case. Therefore, the data may change and reports for the most recent weeks may more dramatically undercount the total number of cases occurring in that week. We continuously receive case reports and work to confirm, process, and report them as quickly as possible.
  • For some cases, sex, race/ethnicity, or age data may not be available and therefore are excluded from an analysis. This means that the total number of cases for each of the charts below may vary slightly.
  • Most of the graphs on this page show COVID-19 case rates rather than case counts. It is important to use case rates when making comparisons between groups that have different population sizes. For example, the White population is much larger than the Native American/Alaska Native population in Minnesota so we would expect to see much higher case counts among White Minnesotans. In order to compare whether one of these two groups is being disproportionately impacted by COVID-19, we must calculate the rate, which is the number of cases divided by the population size. Count data is still available and can be found in the CSV files that accompany each graph.
  • Data for the most recent MMWR week will only contain information for Sunday through Tuesday based on when the data are compiled to create these graphs.

Case Trends

Cases Over Time (7-day Moving Average)

  • Download: 7-day moving average of cases (CSV)

  • Cases over time are shown using a 7-day moving average. To get the 7-day moving average, we add all the cases from the previous 7-days (including the current date) and then divide by 7.
    • A 7-day moving average provides a more accurate representation of case counts by smoothing out any short-term spikes or dips that occur across a week as a result of external factors, such as a facility not being open on certain days or delays in data reporting.
Total positive cases, including reinfections (cumulative) 1,611,246

Case Rate by County of Residence

  • Download: Case Rate by County of Residence (CSV)

  • County rates are calculated using probable and confirmed cases by reported county of residence by week of specimen collection date divided by the county population. The rate is then multiplied by 100,000.
  • Weeks are defined as Sunday through Saturday. Therefore "Last Week" corresponds with the Sunday through Saturday of the week prior to when the data are posted.


Case Rate by Age Group

  • Download: Case Rate by Age Group (CSV)

  • Rates are calculated using probable and confirmed cases by reported age at date of specimen collection divided by the total age-specific Minnesota population. The rate is then multiplied by 100,000.

Case Rate by Sex

  • Download: Case Rate Sex (CSV)

  • Rates are calculated using probable and confirmed cases by reported sex at date of specimen collection divided by the total sex-specific Minnesota population. The rate is then multiplied by 100,000.

Case Rate by Race and Ethnicity

  • Download: Case Rate by Race and Ethnicity (CSV)

  • Rates are calculated using probable and confirmed cases by reported race/ethnicity at date of specimen collection divided by the total Minnesota population of each race/ethnicity. The rate is then multiplied by 100,000.

Variants Circulating in Minnesota

Lineage Distribution

  • Download: Lineage Distribution (CSV)

  • The Minnesota Department of Health tracks variants of SARS-CoV-2, the virus that causes COVID-19, among Minnesota residents. The figure above shows what proportion of all the specimens sequenced were attributable to each variant identified in Minnesota.
  • On a weekly basis, approximately 5% to 20% of cases of COVID-19 have sequencing information available, providing scientists with valuable information about variants circulating in the state.
  • Routine sequencing of SARS-CoV-2 specimens began in January 2021. There is a delay of a couple weeks for posting variant data due to the time it takes to transport specimens, run sequencing tests, and analyze the data.
  • Variants of Concern are separated in the figure and named using World Health Organization (WHO) naming conventions. Variants of Interest (VOI) are included as a single group.
    Additional information about the naming and categorization of variants can be found at WHO: Tracking SARS-CoV-2 variants
