On-campus Surveillance (since June 21, 2021)
*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.

Both Pasadena Public Health and the Los Angeles County Department of Public Health maintain COVID-19 dashboards. To see the latest data for each, click the links below.
Undergraduate Testing Compliance
Each undergraduate, regardless of place of residence, is required to submit two samples per week for COVID-19 testing.
Please note that the numbers from the Week of 6/6/22 reflect the fact that many undergraduate students left campus that week for the end of the term before needing to complete a second surveillance test.
Graduate Student Testing Compliance
Each graduate student who lives in Caltech housing is required to submit two samples per week for COVID-19 testing.
* Undergraduate and graduate students may be exempt from testing if they have recovered from COVID-19 within the last 90 days, or if they have been traveling or not otherwise in residence/accessing campus during this period.
Campus Isolation Housing
Caltech has set aside space in Caltech housing for the isolation of ill individuals, with the intention of reducing the spread of illness.
