Hospitalization Data
Viral Respiratory Illness in Minnesota

Downloadable data: Weekly rates of respiratory virus-associated hospitalizations by season (CSV)

• The Twin Cities metro includes the 7-county metropolitan area (Anoka, Carver, Dakota, Hennepin, Ramsey, Scott, and Washington counties). Greater MN includes all counties in Minnesota that are not part of the 7-county metropolitan area. Statewide includes data for all counties in Minnesota.
• Confirmed RESP-NET cases include hospitalizations that had laboratory confirmation of COVID-19, influenza, or RSV any time from 14 days prior to hospital admission through hospital discharge.
  • Multiple hospitalizations within a two-week period are counted as a single hospitalization.
  • If a person is hospitalized and tests positive for more than one of the included diseases (COVID-19, influenza, RSV) they will be included in the total counts for each disease.
• Rates are calculated by dividing the number of RESP-NET hospitalizations in a given week by the total 7-county metropolitan area population and multiplying by 100,000. Results represent the number of hospitalizations that would occur in a population of 100,000 people.
  • The “combined” rate line is the total of all hospitalizations across all pathogens in this graph divided population. The rate is then multiplied by 100,000.
• Surveillance for COVID-19, influenza, and RSV in RESP-NET relies on clinical testing ordered by a health care provider and does not include at-home tests. Hospitalization rates are unadjusted and do not account for undertesting, differing provider or facility testing practices, and diagnostic test sensitivity. The true burden of COVID-19, influenza, and RSV-associated hospitalizations may be greater than what is shown by these numbers.
• Minnesota RESP-NET data are preliminary and subject to change as more data become available. Rates for recent hospital admissions are subject to reporting delays that might increase around holidays or during periods of increased hospital utilization. As new data are received each week, previous rates are updated accordingly.

• Data in this graph have been smoothed using a 4-week moving average. Moving averages combine the raw counts for the data from preceding days or weeks and then average them (e.g., a 4-week moving average combines data from the current week and the previous 3 weeks and averages them). They are useful for observing trends in data which have larger fluctuations over short periods of time because of small population sizes or rare outcomes. Raw data of the count and rate per week are still available in the downloadable CSV file.

Downloadable data: RESP-NET by County (CSV)

• Confirmed RESP-NET cases include hospitalizations that had laboratory confirmation of COVID-19, influenza, or RSV anytime from 14 days prior to hospital admission through hospital discharge.
  • Multiple hospitalizations within a two-week period are counted as a single hospitalization.
  • If a person is hospitalized and tests positive for more than one of the included diseases (COVID-19, influenza, RSV) they will be included in the total counts for each disease.
• Rates are calculated by dividing the number of RESP-NET hospitalizations in a given week by the county population and multiplying by 100,000. Results represent the number of hospitalizations that would occur in a population of 100,000 people.
• Risk thresholds differ by pathogen and are calculated using cut-points at the 50th and 75th percentiles for the weekly hospitalization rates across multiple seasons/years.  
  • For COVID-19 the thresholds were estimated using data from 2020 – 2024 and the thresholds per 100,000 people are:  
    • Low: < 8.4
    • Moderate: 8.4 – 14.6
    • High: >= 14.7.  
  • For influenza the thresholds were estimated using data from 2014-2024 and the thresholds per 100,000 people are:  
    • Low: <4.5
    • Moderate: 4.5 – 8.1
    • High: >= 8.1
  • For RSV the thresholds were estimated using data from 2020-2024 and the thresholds per 100,000 people are:  
    • Low: <2.0
    • Moderate: 2.0 – 4.0
    • High: >= 4.1
