COVID-19 Dashboard

Updated July 28, 2021 at 1:16 p.m. PDT

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 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.

Total COVID-19 Cases

This table is intended to inform the Caltech community about known cases of COVID-19 within our community in a manner that is respectful of individuals' privacy and wellbeing and in alignment with public health guidance. The counts reported here reflect individuals' self-reported test results as well as results from the on-campus testing and surveillance programs.

The counts include members of the on-campus community as well as employees at off-site facilities (with the exclusion of JPL, which tracks its case count separately). This chart will be updated as SWS receives reports of positive tests from community members, even if their illness occurred more than 14 days ago.

Campus Testing Data

Caltech offers two types of COVID-19 testing through Student Wellness Services (SWS). These services are provided free of charge to members of the community as part of an ongoing effort to proactively screen for and mitigate the risks of infection within the Caltech community.

Caltech's surveillance program, which began November 30, 2020, is intended to identify asymptomatic individuals in the community who are reporting to campus for work.

Beginning June 1, the Institute is excusing individuals who have submitted proof of their fully vaccinated status from participating in the surveillance program. All employees, students, and campus affiliates reporting to campus, even on an occasional or one-day-a-week basis, who have not submitted proof of vaccination must continue to participate.

On-campus Surveillance Testing (November 30, 2020 – June 20, 2021)

The numbers in the tables 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).

Campus Isolation and Quarantine

Isolation of ill individuals is initiated to reduce or eliminate contact between an ill person and others to reduce the spread of illness, while quarantine of potentially exposed individuals is intended to prevent potential spread while testing to see whether these individuals in fact have COVID-19. Please note that isolation or quarantine does not necessarily indicate a positive COVID-19 case; students exhibiting symptoms may be transferred to quarantine housing while they await test results.

Individuals in Avery (since May 2020)

Current Total
Isolation 0 20
Quarantine 0 15

Individuals in Bechtel (since September 2020)

Current Total
Isolation 0 0
Quarantine 0 147

Graduate students arriving at Caltech to live in student housing are required to undergo a COVID-19 test, then quarantine in Avery House or Bechtel Residence for a minimum of one week, and then undergo a retest. Following quarantine and a negative test, they will move into their student housing assignment. Quarantined students will be provided with meals and supportive services during their stay.
