Weekly COVID-19 Tests

The graphs and tables below show weekly trends in University-wide tests and new positive cases since June 1, 2020. Only a limited number of students and personnel are authorized to be on campus and participate in Harvard’s COVID-19 screening program.1

The majority of Harvard’s community continues to work and learn remotely. Individuals authorized to participate in Harvard’s COVID-19 screening are tested regularly (see testing protocols). Data is not combined with other testing sources or providers.

The data below is updated weekly and is current as of 10:30 am on 22-Feb-2021; for daily updates and cumulative tests, cases, quarantine, and isolation data, see the results dashboard.
