Use caution when interpreting case count information.
**Notice** The dashboard will NOT be updated this weekend (May30, 31st) due to a testing event.
*The dashboard will be updated daily by 4:30 p.m., with COVID-19 figures included as of 2:00 p.m.
*Confirmed cases only include people who test positive for COVID-19.
*The true number of COVID-19 cases is likely higher than we know.
*Probable cases of COVID-19 are defined as individuals who have been directly linked epidemiologically to a confirmed case and have symptoms consistent with COVID-19, but who were not tested. Given that a positive COVID-19 test result would not change the measures taken by public health, since a probable COVID-19 case would already be quarantined when symptoms appear, these cases are labeled as probable instead of confirmed. Probable cases are treated as if they were a positive laboratory confirmed case and the actions taken are the same as for a confirmed case. This includes: self-isolation, active contact tracing and daily follow-up by DHD4 communicable disease team.
*Zip codes with 1 or more cases are shown. For zip codes with 1-5 cases, “<5” will be reported as to protect potentially identifiable information. For counties with more than 5 cases, the actual number of cases is shown.
*COVID 19 Cases by Onset Date Chart shows the progression of the COVID-19 outbreak in the DHD4 jurisdiction over time and is known as an epidemiologic curve. Cases are shown by the date of symptom onset – the date when the person began to feel sick – which is important for determining the “incubation period,” or time between exposure and symptoms. It is important to recognize that some people may have had or have COVID-19 and have not been tested. However, the shape of the curve is still informative. The epidemiologic curve is the curve referred to in the phrase, “flatten the curve.”
*Michigan Department of Health and Human Services (MDHHS) defines recovered as an individual who, within the Michigan Disease Surveillance System, has gone 30 days from onset of their symptoms or 30 days from testing positive with COVID-19 and has not died. DHD4 will report cases recovered as they meet this definition. DHD4’s first case was on March 29, 2020.
*Contact tracing represents the number of individuals DHD4 identify as close contacts to positive COVID-19 cases who are being monitored but are not showing symptoms. Numbers shown include the total of those actively being monitored or those that have completed the monitoring process.
*Given the national shortage of testing supplies, not everyone with COVID-19 symptoms will receive a test. In general, tests are given to people who meet priority criteria. Click here to view the criteria for testing. Click here to find a testing site in your area.
*Some people who have COVID-19 will not show symptoms and therefore may not be tested.
*Please note: As the number of cases grow, MDHHS is only able to update their website once per day. We may report a local case before the state is able to include it in their counts. Given that it is our mission to ensure the health of our communities, we feel that it is important to share these results quickly whenever possible.
*Numerous agencies around the State of Michigan enter data into the COVID 19 tracking system and counts on the State of Michigan website might differ due to data entry or reporting errors such as incorrect addresses.
*DHD4 is working diligently with community partners to expand testing capacity, to track COVID-19 in our region, and to quickly share information as we learn more.
