MI Safe Start Map is a dashboard designed to monitor the status of COVID-19 indicators across the state of Michigan. The dashboard tracks and displays the current risk level of Michigan regions and counties due to COVID-19. The goals are twofold:

  • To assist public health officials in making state, regional, and county-level decisions related to COVID-19;
  • To provide the general public with insight into some of the indicators that affect these public health decisions.

Disclaimers

This dashboard presents risk and capacity indicators that are taken into consideration during the State of Michigan's development and implementation of the MI Safe Start Plan. Each indicator is assigned a level of risk. Those levels are taken into consideration, with other epidemiologic information, in assigning the overall risk level for a region. The State of Michigan's decisions about the MI Safe Start plan also take into consideration availability of mitigation and economic factors, among other factors.

The COVID-19 pandemic is a rapidly evolving and unpredictable viral outbreak. The data and associated risk indicators represented here are derived from state and public sources that may contain inaccuracies and that are frequently updated and/or revised. Consequently, there are times that the indicators may be or appear to be inaccurate or conflicting. All data presented on this site is subject to change. The information presented on this site is for informational purposes only, does not constitute legal or medical advice, and does not replace or supersede any guidance or directives issues from the State of Michigan in connection with its MI Safe Start plan. Use caution in making any decisions based on limited or transient data presentations such as those appearing in this dashboard.

Michigan Economic Recovery Council (MERC) Regions

The regions on the map were developed by the Michigan Economic Recovery Council (MERC). MERC regions were developed by merging Michigan's Emergency Preparedness Regions and Michigan's labor sheds – the major areas of the state where people live and travel to work based on U.S. Department of Labor data – so that any outbreak resulting from a return to work could be handled effectively under public health laws.

Data Sources

Cases

Case data are from the Michigan Disease Surveillance System (MDSS), the Michigan Department of Health and Human Services’ web based communicable disease reporting system. Only laboratory-confirmed COVID-19 cases are included. Displayed dates represent illness onset dates. If illness onset date is unavailable, date of testing is used; if date of testing is unavailable, date of referral to MDSS is used. Dates are subject to change over time as better data become available. These totals do not include the cases among prisoners in Correctional Facilities. A future release of the dashboard will include the ability to compare the numbers with and without counts from Correctional Facilities.

Deaths

Death data are also from the Michigan Disease Surveillance System (MDSS). Laboratory-confirmed and probable COVID-19 deaths are included. Displayed dates represent dates of death. If date of death is unavailable, date of last status change in MDSS is used. Dates are subject to change over time as better data become available. These totals do not include the deaths among prisoners in Correctional Facilities. A future release of the dashboard will include the ability to compare the numbers with and without information from Correctional Facilities.

Testing

Laboratory testing data are those diagnostic tests reported to the Michigan Department of Health and Human Services. These totals do not include the diagnostic testing of prisoners in Correctional Facilities. A future release of the dashboard will include the ability to compare the numbers with and without testing from Correctional Facilities.

Region Risk Determinations

Official region risk determinations are provided by the Michigan Department of Health and Human Services. They are used to color-code the map regions. Changes in color codes reflect the dates of determinations of risk levels.

Data Updates

Official data are sometimes revised to correct errors or the arrival of new information about previously reported cases and deaths. Data in the dashboard about earlier dates always reflect the best currently available data, not what was known as of particular dates in the past.

Data last uploaded on September 20, reflecting cases and deaths through September 19 and tests through September 17. Reports on or after September 17 may not yet reflect complete data. For that reason, indicators and trends are not calculated for September 17 or later.

Indicator Details

Test Results

Percent Positive Tests

Percent positive tests is the number of positive tests divided by the total number of tests for a particular day. When testing levels are stable, this metric identifies increases or decreases in the epidemic relative to other causes of respiratory infection. This metric is commonly used in community monitoring studies of influenza and other respiratory viruses. Evaluations of percent positivity (number of positive tests / total number of tests) also enable a look at adequacy of testing in a population t

Number of Tests Over Prior 7 Days

This is the total number of tests performed over the previous 7 days. Testing is important to identifying COVID-19 cases, and may drive up new case volume. Use this metric to see if there has been an increase or decrease in testing over a week that could affect case counts.

New Cases

Number of daily cases/million

The number of daily cases per million is the number of new cases with onset on that day divided by the number of people in that county or MERC region. It is adjusted to a 'per million' people scale so that counties and regions can be easily compared.

Threshold Ranges

Threshold ranges in our visualizations have been promoted by public health experts. They represent absolute levels of cases which reflect potential levels of transmission in a community. A geographical area is “high risk” at or above 40 new daily cases per million residents. Below 20 new daily cases per million, there is a “medium” risk of community transmission and below 7 there is “low” risk.

Number of New Cases

The number of new cases is a count of the cases with onset on that particular day.

3 Day Case Surge

3-day case surge is defined as 3 consecutive days in which there is an increase of 10% or more in new cases each day. Given the high infectiousness of the virus, this metric provides early signals of a sudden increase in infection.

Who Built It

MI Safe Start Map has been collaboratively developed by a group of volunteer faculty, students, alumni and friends of the University of Michigan School of Information and the University of Michigan School of Public Health.
