The confirmed cases chart will be updated Fridays by 1 p.m. Our goal is to be open and transparent, which we believe is essential to help stop the spread of the virus.

A Note on the Data
Northwestern introduced self-reported at-home and off-site test results into the data beginning the week of Dec. 17. Community members generally report off-site or at-home test results only in the case of a positive test, inflating the resulting positivity rate. Self-reported test results will continue to be reflected in the data going forward. Northwestern offered minimal on-site testing during the weeks of Dec. 17-23 and Dec. 24-30 due to Winter Recess, so those weeks are largely reflective of off-campus self-reported cases.
On Jan 21, 2022 we posted adjusted totals for Dec 31-Jan 13 to remove multiple positive results from the same individuals who re-tested after their 5-day isolation period.
