U-M COVID-19 Data

Oct. 12, 2021 Update:

U-M officials report the rate of new cases of COVID-19 among the student population remains at a low-level plateau. Case counts have remained stable in the employee population while the pattern of activity in the state and region continues to track upward. The largest growth of cases is occurring in the 5-18 year old age range, which may impact employees and students with children. Resources for care are available here. 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 testing at University Health Service remained steady last week: 663 tests were performed and 19 (2.9%) were positive while test positivity for strep was 5.7%, and 1.4% for RSV and one case of influenza (0.5%). 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 at 2% occupancy.
