Beginning July 1, 2022, MIT offers unobserved PCR testing to individuals approved to live, study or work on campus who attest to experiencing COVID-19 symptoms. Due to this change as well as the increase in at-home rapid antigen testing, we are no longer reporting positive test results through the Institute’s testing program on MIT’s COVID-19 dashboard. Without required surveillance testing in place, dashboard data no longer provide an accurate picture of the prevalence of COVID-19 in the MIT community. A better benchmark is the MWRA wastewater testing data, which is independent of testing rates and has correlated well with the virus’s prevalence in our community. Institute leaders closely monitor the MWRA wastewater testing data to determine whether changes to MIT’s COVID-19 policies are necessary.

For past data from MIT’s COVID-19 dashboard, see the summary of required COVID testing (August 15, 2021 to March 13, 2022) and optional COVID testing (March 14, 2022 to June 30, 2022).
