What is the Contact Tracing Process?

Contact Tracing

Contact tracing is the process of identifying, notifying, and monitoring anyone who came in close contact with an individual who tested positive for COVID-19 while they were infectious (2 days before onset of symptoms until the end of the person's isolation period).  Contact tracing is a key strategy for preventing the further spread of infectious diseases, such as COVID-19. Close contacts of a case are considered to have been exposed to COVID-19 and may go on to develop the disease.  Identifying and quarantining close contacts limits their ability to spread disease should they become infectious and helps to limit community spread

What Does Contact Tracing Look Like?

  1. When an individual is tested and confirmed positive for COVID-19, they are asked to isolate for a minimum of ten days.  They must also be fever free for 72 hours without the use of anti-fever medication and show an improvement in symptoms before isolation can be discontinued.  These individuals are called cases.
  2. Positive COVID-19 test results are reportable to the PA Department of Health.  Within 24 hours of receiving the positive result, trained public health staff conduct an interview with the case to obtain a list of close contacts they had while infectious.  Cases are considered to be infectious beginning two days before onset of symptoms or two days before the date of the positive result if the person did not have symptoms. The cases are encouraged to utilize calendars, social media, etc. to remember where and who they were around during their infectious period. During the case investigation, the public health staff attempt to obtain as much information as possible on the contacts (address, phone, email, etc.) and then share the contact information with the designated contact tracers.
  3. Contact tracers reach out to educate, inform and support those who had a known close contact with a COVID-19 positive individual through phone calls, texts, emails and mailings. To protect patient privacy, close contacts are only informed that they may have been exposed to an individual with COVID-19.
  4. Close contacts are told to:
    • Stay home and maintain social distancing through the end of their quarantine period (10 days from the date of their last exposure to a case). 
    • Monitor themselves daily for symptoms of COVID-19, including checking their temperature
    • Be aware that they could possibly spread the infection to others, even if they do not feel sick.
    • Exceptions to these instructions may occur for healthcare workers and critical infrastructure workers who have no symptoms.  They may be permitted to work with special precautions in place, such as daily symptom checking prior to reporting to work and masking while at work.
  5. With consent, contacts are enrolled into a daily symptom monitoring system called Sara Alert.  The Sara Alert system sends the contacts a daily symptom questionnaire via text, email, or robo-call, using whichever method is preferred by the contact.  Public health staff and contact tracers review the contacts' responses on a real-time dashboard and promptly reach out to anyone who answers "yes" to having a symptom(s). 
  6. If a contact develops symptoms, they should isolate themselves and let their healthcare provider and public health staff know. The contact will be evaluated to see if they need medical care and/or COVID-19 testing.                      

A Contact Tracer Will Never Ask You For:

  • Your social security number, financial or bank account information, or personal details unrelated to COVID-19;
  • Photographs or videos of any kind;
  • Your passwords; or
  • Money or payment. 
  • Your personal information or send you any website link via a SMS/text message.

A Contact Tracer WILL Ask:

  • For verification of your date of birth, address, and any other phone numbers you may have; and
  • If you have already tested positive for COVID-19 they may also ask the date of your test and the name of your insurance company as additional verification.

If you would like to verify if the caller does in fact work in contact tracing, call the PA Department of health at 1-877-PA HEALTH to verify.

What Terms Should I Know When It Comes to Contact Tracing?

  • A contact is an individual who had close contact while the case patient was infectious. This person should quarantine themselves, meaning they should stay at home to limit community exposure and watch to see if symptoms develop.
  • A contact of a contact is an individual who had or continues to have close contact with a contact. This person should take everyday preventative actions, like washing hands, covering coughs and sneezes, and cleaning surfaces frequently, however quarantine is not necessary. This person should also be alert for symptoms.
