Your health and the health of our community is our primary concern. Our collective safety requires everyone to consistently follow best practices for preventing the spread of COVID-19—including getting vaccinated, wearing a mask if you are not vaccinated, following proper hygiene, and reporting any symptoms. 

Any Johns Hopkins community member who feels ill or is concerned about exposure is encouraged to call the Johns Hopkins COVID-19 Call Center at 443-287-8500, seven days a week, between 7 a.m. and 7 p.m. The JHCCC supports all JHU students, faculty, and staff, although it is primarily intended for people experiencing COVID-19 symptoms who are currently within driving distance of Baltimore. Employees should also use the call center (not Occupational Health) if you need clearance to return to work after being tested or recovering from COVID-19.

Compliance with Safety Guidance

All members of the university community are expected to fully comply with the policies, protocols, and guidelines outlined on this website and communicated via email. Noncompliance with COVID-19 campus health and safety guidelines could result in loss of access to university facilities as well as corrective and/or disciplinary action. 

If you have a concern or complaint regarding noncompliance of JHU COVID-19 safety measures by a member of the Hopkins community, please make a confidential report immediately via the online form or by calling 844-SPEAK2US (844-773-2528). 

For live, immediate response, also consider using the LiveSafe app to report concerns directly to Campus Safety & Security (with options for anonymous reporting).

Asymptomatic Testing

The university currently has six campus testing locations where specimens can be collected. Affiliates must come to one of these locations in order to provide their specimens for mandatory or voluntary testing. 

Effective July 1, the following testing rules apply: 

  • Once-weekly COVID testing will be required for vaccinated, residential undergraduates  
  • Twice-weekly testing will be required for all unvaccinated faculty, graduate students, postdoctoral fellows, and staff
  • Testing on demand will remain available for all affiliates 

Required Daily Health Checks

Faculty, staff (including bargaining unit staff), and students who come to campus to work, study, or for any other reason are required to complete a daily health check on the Prodensity mobile app or website.  

There are two ways to complete the health check:  

  1. Download the Prodensity app (for iOS or Android devices) 
  2. Visit the COVID Health Check website 
Personal Safety Practices

Read protocols and recommendations related to face coverings, physical distancing, handwashing, and more

Monitoring Symptoms

The university is relying on everyone to engage in daily self-monitoring; you may not report to campus unless you are free of all symptoms potentially related to COVID-19

Frequently Asked Questions

I feel ill or am concerned about exposure to the SARS-CoV-2 virus. What should I do?

All Johns Hopkins affiliates (students, trainees, staff, and faculty) are strongly encouraged to use Johns Hopkins resources when symptomatic or concerned about exposure. Anyone who feels ill or is concerned about exposure is encouraged to call the Johns Hopkins COVID-19 Call Center at 833-546-7546, seven days a week, between 7 a.m. and 7 p.m. The call center is staffed by Johns Hopkins nurses and physicians and specially trained nursing and medical students. When you call, a representative will instruct you about next steps depending on your circumstances. They will arrange for testing if needed, assist in transmitting information to Occupational Health, and conduct contact notification. Further, the caller will be given instructions regarding quarantine before a test can be secured. The criteria for testing are updated on a regular basis, and the most current criteria will be used when there is an assessment over the phone.

As has always been the case, individuals who have symptoms of COVID-19 or have tested positive for infection with SARS-CoV-2 should self-isolate at home except to get medical care until it’s safe to be around others.

Can you receive vaccines other than the flu vaccine on the same day as the COVID vaccine?

No vaccines other than the flu vaccine should be given during the time period of two weeks prior to the first COVID vaccine through two weeks following the final COVID vaccine.

How long after a natural COVID infection should you wait before getting the vaccine?

In most cases, you should wait until you are out of isolation (all COVID symptoms have resolved) to get the vaccine, but no longer than 90 days. If you were treated with monoclonal antibodies and/or convalescent plasma, you should wait 90 days before getting the vaccine. Affiliates may request a medical exception to wait to get the vaccine until the 90 days has elapsed.

Where can I get more information about COVID vaccine safety and effectiveness?

We have a tremendous amount of information and support available for those who have questions about the vaccine or want to learn more. JHM has compiled a set of resources on Covid vaccine effectiveness and safety and what to expect when getting vaccinated. JHU’s Coronavirus Resource Center has extensive information about how the vaccines were developed and tested, as well as data on their distribution in the U.S. and internationally.

How can I be sure that the facilities are ready to receive everyone back at the same time?

Divisional business officers, HR managers, IT managers, and others have worked to ensure that facilities will be open and ready for staff and faculty to return, and will be communicating plans to unit leaders. If you have specific questions, please contact your supervisor or HR manager.

Do I still need to use Prodensity once I have uploaded proof of vaccination or received an exception?

Yes. All students, employees, and contractors who are on-campus must complete a daily health check using Prodensity. If you are 100% remote or online, you should change your status to indicate you will not be coming on campus using Prodensity. For more information, read a Prodensity tutorial on how to ensure your status is up-to-date.

How does the university learn if an employee or student working in a lab tests positive for COVID-19?

All students, faculty, and staff who are participating in on-campus activities should monitor themselves daily for any symptoms. Anyone who has symptoms associated with COVID-19 or who has concerns about exposure to COVID-19 is strongly encouraged to call the Johns Hopkins COVID Call Center, or JHCCC, at 833-546-7546 to be triaged to determine if they meet the criteria for testing. In the case of employees, their supervisor will be informed that the employee is “off-duty” until cleared. In the case of students, their school’s Student Affairs representative will be notified that the student is “off-duty.” The student’s name will be shared with the student’s consent.

The JHCCC will inform you of your test result if you are tested at a Johns Hopkins facility. If your test is negative, your supervisor or Student Affairs Representative will receive a message that you have been cleared. If you test positive, you will remain “off-duty” and there will be no additional communication to your supervisor or Student Affairs representative until you are cleared. You are encouraged but not required to share the information with your supervisor or Student Affairs representative.

How do I get cleared to go back to work or class after I recover from COVID-19?

Current CDC guidelines allow for anyone who is not severely immunocompromised to return to work if they meet the following criteria:

  1. At least 10 days have passed since symptom onset or asymptomatic testing
  2. At least 24 hours have passed since last fever without using fever-reducing medications
  3. Symptoms have improved.

Employees who believe they have met this criteria should call the Occupational Health Services at the Johns Hopkins COVID Call Center (410-614-6000) for an evaluation and clearance to return to work. Individuals who were first notified of the employee’s “off-duty” status will be informed by OHS that they are cleared to “return to duty.”

Students who need clearance to return to class should be instructed to do the following:

  • Students from the schools of Medicine, Public Health, and Nursing should contact University Health Services at 410-955-3250 for an evaluation and clearance to return to class. Individuals who were first notified of the student’s “off-duty” status will be informed by UHS that they are cleared to “return to class.”
  • Students of any other JHU school should contact the Student Health and Wellness Center at 410-516-8270 for an evaluation and clearance to return to class. Individuals who were first notified of the student’s “off-duty” status will be informed by SHWC that they are cleared to “return to class.”

Why are residential undergraduates required to test even if they have been vaccinated?

Our testing policies are informed by the most successful practices that have emerged from our peer institutions and from emerging data about the pandemic.  

Undergraduates, because they typically live in congregate settings, tend to be at higher risk of contracting COVID, and of spreading it to a larger number of people, making early detection of asymptomatic cases particularly important in this group. As such, testing is an additional measure of protection for our community.

What are the current distancing requirements?

Physical distancing requirements have been lifted indoors and outdoors, including in elevators and bathrooms. Capacity restrictions have also been lifted on buses and shuttle vans.

Physical distancing is required for unvaccinated affiliates when eating indoors (in addition to the masking and testing requirements outlined on this website). Spaces for eating will be available both in distanced and undistanced formats.

What is being done about air ventilation in buildings in light of the danger of airborne transmission?

Following CDC and ASHRAE guidance, JH Facilities assessed and improved building ventilation where possible—the number of air exchanges per hour, filtration,  and amount of fresh air intake. Facilities is also performing preventative maintenance checks to ensure filters have been changed and that systems are working properly.
