Historic On-campus Surveillance Testing Data

The table below contains historical surveillance-testing data from November 30, 2020 to June 20, 2021. To view data from June 21 onwards, visit the main COVID-19 Dashboard and refer to the Campus Testing Data section.

The numbers in the table above reflect only surveillance testing for the Caltech campus community. Off-campus facilities also have surveillance programs of their own. Positive results detected through those programs will continue to be reported in the positive case table above, as well as through timely email notifications (opt-in required).
