This page provides information on Caltech's on-campus surveillance and symptomatic testing programs and the current counts of individuals in campus isolation and quarantine facilities. These numbers reflect both individuals' self-reported test results as well as results from the on‑campus testing and surveillance testing programs administered by Student Wellness Services (SWS).

This data is updated weekdays by 2 p.m. PT.

You may also opt-in to receive timely email notifications of new positive COVID-19 cases among symptomatic and asymptomatic members of the campus community.

*Final number pending confirmatory testing. More detail about the surveillance testing process can be found on the Testing page.

SWS Testing of Symptomatic/Exposed Individuals (since March 2020)

As of January 2022, Caltech will no longer be reporting granular statistics on the testing of symptomatic/exposed individuals due to the high volume of testing and reports of illness being processed by SWS. Positive cases detected from symptomatic/exposed individual testing will continue to be reported in the Total COVID-19 Cases table (above) and via emailed positive case memos.  To view historic testing data collected from March 2020 to December 2021, click here.
