COVID-19 Dashboard

Updated December 3, 2021 at 1:38 p.m. PST

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.

All undergraduate students (regardless of living location) and graduate students who live in Caltech Housing, as well as any employees, graduate students, or campus affiliates who have an approved exemption from Caltech's full vaccination requirement are required to participate in the surveillance testing program. These individuals must submit two samples each week.

All other members of the Caltech community are eligible to voluntarily participate in the surveillance program on an opt-in basis, submitting up to two samples a week.

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

Positive Negative Pending Total
Students 31 1,460 0 1,491
Staff, Faculty, and Postdocs 45 1,526 0 1571

On-campus Surveillance (since June 21, 2021)

Bolded counts represent the number of samples that were picked-up but are awaiting lab processing.

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).

Undergraduate Testing Compliance

Each undergraduate, regardless of place of residence, is required to submit two samples per week for COVID-19 testing.

* 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.

Graduate Student Testing Compliance

Each graduate student who lives in Caltech housing is required to submit two samples per week for COVID-19 testing.

* 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 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.

At Caltech, the dedicated quarantine space is only used to house unvaccinated individuals (those with a verified medical exemption that has been approved by SWS) in the event of an exposure to a confirmed case of COVID-19. Following public health guidance, vaccinated individuals who have been identified as close contacts are directed to monitor symptoms twice per day, test at day 5-7 post exposure, and are permitted to participate in essential academic activities and may remain in their housing assignments.

*An earlier version of this section also included a record of the 147 graduate students who were all required to quarantine in Bechtel before accessing campus in Fall 2020. Students are no longer necessarily mandated to quarantine upon arrival to campus unless they meet certain criteria. For consistency and simplicity, the table has been streamlined to omit those 147 previous quarantines.
