Stanford COVID dashboards

This page provides various daily and weekly updates about COVID surveillance testing, Health Check submissions, isolation, and prevalence in the Stanford community. We provide recent and historic metrics for both students and employees since the onset of COVID with comparative measures to the surrounding area.

Summary as of Monday, March 13, 2023

• Isolation: As of today, there are 65 students isolating, most of whom are in Stanford student housing. At this time last week, the comparable number was 28.
• Student testing: Positive test results for students during the week of Mar 6th – Mar 12th totaled 47. This compares to 15 for the prior week of Feb 27th – Mar 5th.
• Faculty, staff and postdoc testing: Among this population, 57 total positive test results were reported for the week of Mar 6th – Mar 12th; 9 from Color testing and 48 from either outside providers or individuals’ own rapid antigen testing at home. This compares to 54 for the prior week of Feb 27th – Mar 5th.
• Vaccination: We have at least 95% of all Health Check users having attested to being fully vaccinated.
• Updates are paused during the university’s winter closure and will resume on January 9, 2023. Positivity rates in the displays below reflect Stanford’s surveillance testing program provided by Color, not rapid antigen tests or any other testing.

Students

The data below is from student-reported positive tests, Color or Stanford PCR testing. Details of this program are available here. In addition, across all time periods, the data below reflect the results of student tests for COVID undertaken or facilitated by Vaden Health Center, as well as the results of student-athlete surveillance testing for COVID.

Stanford student metric definitions

• Vaccinated metrics reflect the number of partially and fully COVID vaccinated individuals. This category will be updated monthly and sourced from Health Check user data based on the vaccination question only. Some users may be submitting while working remotely while others prior to coming onsite. Partially vaccinated are those having received only one dose of a two series. Typically, there is a 3-4 week waiting period to receive the second dose. Individuals are considered fully vaccinated two weeks after receiving a single-dose vaccine or two weeks after the second dose in a two-dose series. This guidance applies to COVID-19 vaccines recommended by the CDC and currently authorized for emergency use by the U.S. Food and Drug Administration: Pfizer-BioNTech, Moderna, and Johnson and Johnson (J&J)/Janssen COVID-19 vaccines. This also applies to COVID vaccines that have been authorized for emergency use by the World Health Organization (e.g. AstraZeneca/Oxford, etc).
• Total Health Check surveys reflects self-reports of daily surveillance status using the university’s Health Check app since May, 2020. This includes reporting of symptoms, temperature monitoring, exposures, and recent travel history.
• Total confirmed positive cases reflects a cumulative measure of the number of Stanford students living on, or near campus and enrolled or affiliated when they were diagnosed with COVID. This dates back to March, 2020 and reflects test results from any testing provider, not just testing provided by the university as shown in the graphical display above.
• Current cases in isolation on campus reflects the number of students currently in isolation on the Stanford campus following a positive COVID test result.

Faculty, staff and postdoctoral scholars

Beginning Aug. 26, 2020, the display below shows the results of Stanford’s on-campus COVID surveillance testing program for faculty, staff and postdoctoral scholars, administered by Color. Details on this program are available here. In addition, across all time periods, this display includes the results of testing of faculty, staff and postdoctoral scholars provided or facilitated by the Stanford University Occupational Health Center. The data do not include testing performed by other providers.

• Vaccinated metrics reflect the number of partially and fully COVID vaccinated individuals. This category will be updated monthly and sourced from Health Check user data based on the vaccination question only. Some users may be submitting while working remotely while others prior to coming onsite. Partially vaccinated are those having received only one dose of a two series. Typically, there is a 3-4 week waiting period to receive the second dose.

• Total Health Check surveys reflects self-reports of daily surveillance status using the university’s Health Check app since May, 2020. This includes reporting of symptoms, temperature monitoring, exposures, and recent travel history.
• Total confirmed positive cases refers to positive cases among Stanford faculty, staff and postdoctoral scholars that were made known to Stanford through self-reporting into Health Check, hospital notification, or other reporting means, and verified by our clinicians, dating back to March, 2020. This reflects test results from any testing provider, not just testing provided by the university as shown in the graphic display above. These individuals may or may not have been working recently on campus; many university employees have been working remotely since March 2020. Please note that this count includes School of Medicine personnel including those working in patient-facing clinical settings.

Notes on data displays above

For the displays of Stanford testing results shown above, please note:

• Test results are logged based on the date a testing sample is taken or collected.
• Data on Stanford’s surveillance testing program are updated weekly to ensure validation of results. However, if there is a significant outbreak of COVID at Stanford, the university community will be informed on an expedited basis.
• Individuals may be tested multiple times. “Cumulative tests” reflects the total number of tests performed, not the number of individuals tested.
• The graphic displays of surveillance testing results only reflect results from the testing sources listed and do not include data from other testing providers.
• At the start of the pandemic through early September 2020, Stanford reported on its website a cumulative number of COVID-19 cases the university was aware of among faculty, staff, students and postdoctoral scholars, living in any location and receiving a test result through any provider. This count totaled 137 as of early September. As of Sept. 14, the university has shifted to the above data reporting, which displays results of the surveillance testing now being provided on-site to students and employees by the university, along with separate cumulative numbers of COVID-positive cases the university has learned of. These cumulative numbers only include students living on or near the Stanford campus at the time of their positive test result.

In the event of a positive test

Those who test positive through surveillance testing should self-isolate and refrain from leaving their isolation housing if living on campus or coming to campus if living off campus. Those living on campus in R&DE-assigned housing will receive isolation support and accommodations, including meal delivery at no cost to students. 

If you receive a positive test result, you will be asked to immediately complete Health Check to update your test status. Vaden Health Services (for students) or the university’s Occupational Health Center will reach out to you about receiving a confirmatory test and will initiate exposure notification for close contacts as defined here. In the meantime, you must remain self-isolated based on the positive results of the first test.  Expect an additional call or follow-up by the local county public health department for contact tracing efforts. 

If you are experiencing severe symptoms, including difficulty breathing, contact your healthcare provider immediately.
