In order to begin implementing recent CDC updates to isolation and quarantine guidelines, the Delaware Exposed Quarantine Clearance Letter web portal is currently offline and clearance letters are unavailable.

Please also be advised that Division of Public Health (DPH) systems may continue to automatically generate clearance letters for individuals who finish their isolation or quarantine period based on previous guidance. DPH will not be able to issue corrected letters using the newly released guidance, at this time.

As a reminder, clearance letters are NOT required by Delaware Division of Public Health (DPH) to return to work or school. Please consult your employer or school for further guidance.

Contact Tracing IconWhat is Contact Tracing?

In contact tracing, public health staff work with an individual who has a positive test for COVID-19 to help them recall everyone with whom they have had close contact during the time-frame while they may have been infectious.


If you get a call from (302) 446-4262, or your caller ID says DE PUBLICHEALTH, please answer the call.

That’s a representative from the Delaware Contact Tracing Program calling to give you important information about your health. Please answer the call and take the time to speak with our contact tracers to help with our fight against COVID-19.


How you can help:

  • Provide a valid, up-to-date phone number when you get tested so we have the best contact information to reach you.
  • Ensure your doctor has your current phone number on file if you get tested by your primary care provider.
  • If you test positive, start thinking about the people you have had close contact with recently.
