COVID-19 Dashboard

These data represent the results of testing at the on-campus testing center as part of our asymptomatic testing program for those who are in residence or who have been approved to come to campus for work. Testing is conducted during weekdays. Contact tracing and notification are conducted seven days a week.

This dashboard will be updated every Monday–Friday (except for College holidays).

Please Note: Broad Institute has recently reported a sharp increase in testing demand at this time and we therefore anticipate delays as they adjust staffing levels during the early days of January. This longer result turnaround time impacts our ability to update the College dashboard in real time. However, we are making every effort to update the dashboard as soon as test result information is available to us.
