- Recovered note: Recovery for mild to moderate illness is defined as no fever for over 24 hours and improving symptoms and at least 10 days since symptoms started or since the first positive test.

- Reports of positive cases to the health department from testing institutions may be delayed by a day or more. Due to this, the current day has been excluded from the New COVID-19 Cases Reported per Day chart.
- Due to a backlog of test results, counts of cases reported on 3/31 (purple) were abnormally elevated. This number has been changed to reflect the average diagnoses per day of that week (43 cases). The true number of reported cases on 3/31 was 90.

Disparities
We know viruses do not discriminate based on location, race, ethnicity, or national origin. However, viruses like COVID-19 can highlight health disparities that are deeply rooted in our society. COVID-19 is disproportionately affecting some communities in Washtenaw County, including Ypsilanti and Ypsilanti township zip codes and our county’s African American population. Similar disparities have also been seen in Michigan and elsewhere in the United States. Read more about why these inequities may be present, how the Washtenaw County Health Department is working with communities facing health disparities, and community resources.
People of every race, economic status, and age are at risk for coronavirus and should continue taking every precaution to help slow the spread of illness. We must continue to push for policies that address the inequities that this pandemic has brought to light, including paid time off and access to health insurance. Discrimination and disparities are unjust and put us all at greater risk. Individuals in need of essential resources can view Washtenaw County Office of Community and Economic Development’s list of community services or call 2-1-1.
We have a responsibility to provide data that reflects health inequities so that everyone can take action and have the ability to protect themselves from COVID-19. We continue to work with community partners to address these inequities.
Evidence of Community Spread
There is evidence of community spread locally. We have seen cases with no known contact with confirmed cases of COVID-19 or recent travel. Washtenaw County Health Department continues to work with diagnosed individuals to identify close contacts so they can be notified, quarantined, and alert to the possibility of symptoms.
Because there is evidence of community spread, the Washtenaw County Health Department is no longer naming public low-risk exposure locations. Residents can assume there is a possibility the virus may be present when they are in public places in the community. The Health Department is not announcing evidence of community spread to cause panic, but to reinforce that people should be taking all recommended prevention measures.
