U-M COVID-19 Data

Oct. 19, 2021 Update:

U-M officials report a slight uptick in employee COVID-19 case counts while the rate of new cases among the student population remains at a low-level plateau. Consistent with the individual testing data, wastewater surveillance continues to show findings of low COVID-19 activity on and around the U-M campus. U-M student cases currently represent 5% of the cases in Washtenaw County. COVID-19 testing at University Health Service remained steady last week: 783 tests were performed and 17 (2.2%) were positive while test positivity for strep was 4.8%, and 3.7% for RSV, and zero cases of influenza. The majority of student COVID-19 cases were classified as having mild symptoms. The U-M community is reminded to get a flu shot. U-M Quarantine & Isolation Housing is currently about 3% occupancy.
