Contact tracing is a critical component of Philadelphia’s response to the COVID-19 pandemic. If you are contacted by the Health Department, please answer or return these calls/texts. They are not spam.
About contact tracing
Contact tracing is an important tool that health departments use to fight diseases. In general, contact tracing involves identifying people who have an infectious disease and their “contacts” (people who may have been exposed) and working with them to stop the spread of the disease.
Participation in contact tracing is voluntary. People can decline to participate at any point, but participating fully can help stop the spread of the disease and save others’ lives.
Right now, contact tracing is one of the best ways we have to stop the spread of COVID-19, also known as the coronavirus.
If you’ve just been told you have COVID-19, learn how to notify your own contacts.
Contact tracing is confidential and secure.
Case investigators and contact tracers will never:
- Release information collected from COVID-19 tests or by our contact tracing staff to any law enforcement agencies, including ICE.
- Ask about your immigration status.
- Tell a contact who gave us their contact information.
- Ask for Social Security numbers, credit card numbers, or bank account numbers.
How to verify a call is legitimate
A Health Department contact tracer will:
- Call from (215) 218-XXXX.
- Text from 77290 or (833) XXX-XXXX or (855) XXX-XXXX.
- Offer to have you call us back using the number on the City’s website (215) 685-5488.
- Only send email messages from a phila.gov or dimagi.com address.
Some healthcare systems in Philadelphia may be doing contact tracing with their patients, but most contact tracing is done by Health Department employees.
How it works
Contact tracing for COVID-19 begins when a specially trained case investigator from the Health Department contacts a person who has tested positive.
The case investigator will help the person make a plan to isolate themselves (stay away from others) and keep an eye on their symptoms. In the home, anyone sick or infected should separate themselves from others by staying in a specific “sick room” or area and using a separate bathroom, if available.

The case investigator will also ask for the names and contact information of anyone the person with COVID-19 has had close contact with recently.
A close contact is someone who was within 6 feet of a person with COVID-19 for at least 15 minutes. This usually includes household members, intimate contacts, and caregivers, but can include others.
Next, a contact tracer will contact each of these “contacts” to tell them that they may have been exposed to COVID-19. The contact tracer is not permitted to reveal who provided their name; that information is private.
Our contact tracers will contact you via phone or text with one of these phone numbers:
- (215) 218-XXXX (phone)
- 77290 (text)
- (833) XXX-XXXX (text)
- (855) XXX-XXXX (text)
The contact tracer will tell the “contact” that they need to quarantine, or stay at home away from others, for 10 days. They will also give guidance for shortening the length of quarantine to 7 days with a negative test. The contact tracer will enroll the “contact” in automatic symptom monitoring by text (SMS) every day for 14 days after their exposure to check on their symptoms (or provide a phone call instead if preferred)
