Johns Hopkins COVID-19 Testing Dashboard

If you are a Johns Hopkins affiliate who feels ill or are concerned about exposure, you are encouraged to call the Johns Hopkins COVID-19 Call Center (JHCCC) at 833-546-7546, seven days a week, between 7 a.m. and 7 p.m.

On this page, we summarize data on COVID-19 testing and test-positive cases among affiliates whose testing is conducted by the JHCCC and whose results have been reported in the Johns Hopkins Electronic Medical Records system. Employees or students who have received a COVID-19 test outside of the Johns Hopkins network may not be included in these data.

These data reflect testing of (i) symptomatic Johns Hopkins affiliates who contact the JHCCC; (ii) Johns Hopkins undergraduate students in residential housing; and (iii) beginning September 14, testing of participants in the Johns Hopkins epidemiological surveillance study.

Note that due to differences in testing parameters and the focus of our testing on individuals who are symptomatic, a ‘test positivity’ rate for COVID-19 derived from this data would likely be higher than one calculated for the general population or when compared to peer institutions and/or data reported from widespread, community-based testing civic authorities.

In addition to summary data for the fall term, we include a cumulative record of COVID-19 testing results since testing began in March 2020. Student data includes both undergraduate and graduate students. Post-doctoral fellows, medical residents and fellows, and medical house staff are included in the employee counts.

These data are presented to provide a general sense of the status of the COVID pandemic in the Johns Hopkins Community. We have taken care to protect individual privacy, which is why these data do not identify the workplace or division of Johns Hopkins affiliates who test positive.

Frequently Asked Questions

Will the university provide a more detailed breakdown of positive cases by location?

No. Specific locations of cases will not appear on this page out of concern for the privacy of COVID-positive Johns Hopkins affiliates. Providing more detailed statistics by location could allow people to—by inference—determine who is COVID-positive given the relatively small number of cases.

How is the university using information about positive test results to protect the Johns Hopkins community?

University officials are alerted of positive cases when employees or students are tested at JH testing sites. If it appears that you may have been in contact with an employee or student who has tested positive, you will be contacted directly and evaluated for possible testing, isolation or quarantine. If you are not contacted by the JHCCC, it means the JHCCC has determined that no meaningful contact with, or exposure to, a COVID-19-positive affiliate has taken place.

More information about testing, investigation, and notification can be found in our Return to Campus Guidance and the JHCCC web page.

How is meaningful contact defined?

JHU defines meaningful contact as being less than 6 feet from a person who has tested positive for COVID-19 (with or without a mask) for more than 15 minutes.

Who is included in these counts?

The university maintains a record of any employee or student who is tested for COVID-19  through the Johns Hopkins electronic health record (Epic) or at a location that shares data through a cooperative electronic medical records agreement via a system called CRISP (connected providers are shown here). If an employee or student was tested at a location that is not affiliated with Johns Hopkins either directly or through CRISP, they will not be included in these counts. Student data includes undergraduate and graduate students. Post-doctoral students, medical residents and fellows, and medical house staff are included in the employee counts.

Why is the positivity rate not included in this dashboard?

Test positivity rates are a metric used to help public health officials determine if their state or county is testing enough of its population for the size of its epidemic. Importantly, positivity is a measure of testing capacity, and can be used to inform our interpretation of case trends, but it is not a measure of how prevalent a disease is in a community. Because the current Johns Hopkins approach to testing is based on three different approaches — twice-weekly testing of the small number of students living on campus, medical management testing of symptomatic individuals and soon the repeated testing of participants in an epidemiological surveillance study — the positivity rate would not have the same relevance in our context as it does for state and local health departments, and so the university is not publishing it at this time.
