What are common misconceptions about contact tracing?

Last Updated: 11/09/2021

Q: If I test positive for COVID-19, do I have to tell the contact tracer everyone I was in close contact with?

Your help is the key to stopping the spread of COVID-19 and protecting your loved ones.

If you tested positive, you may have spread the virus to others without knowing it. Those individuals could now be infected and putting their loved ones at risk.

That's why if you test positive, we ask you to share your close contacts –anyone you spent 15 minutes or more with over a 24-hour period and were within 6 feet of while you were infectious (2 days before onset of symptoms to 10 days after) – solely for the purpose of helping those people get tested or quarantine as they could be infecting others.

Your information is confidential. Your name will not be released to your contacts or your COVID-19 status – that information will only be known to public health officials and our local health department partners, if needed.

Contact tracing goes hand in hand with testing, and is critical to supporting patients with suspected or confirmed infection. For COVID-19, the ability to scale our contact tracing capacity is how we will break the chain of transmission, slow community spread, and restart the economy – but we cannot succeed without your help.

Q: If I'm exposed, will I be forced to separate from others who have not been exposed? What if I'm a single parent or living with another family?

Individuals who may have been exposed to COVID-19 are expected to follow the direction of public health officials when asked to self-quarantine.

Self-quarantine means that you will stay in your home as much as possible so that you don't infect others. Your family members will stay with you. However, there are things you can do to help ensure that your family isn't infected and contact tracers can provide more information about how to do that.

When a contact tracer calls, they will discuss any needs you may have, inquire about your living situation, and connect you with additional support if you require help. The State is securing beds at hotels, field medical stations, and other locations for individuals who cannot safely quarantine at home.

In addition, you will learn more about community support available to you such as job security, unemployment, child care resources and food assistance such as SNAP. For example, New Jersey has taken steps to protect workers during the COVID-19 pandemic. Under a new law, your employer can't terminate or refuse to reinstate you if you have, or are likely to have, an infectious disease which forced you to miss time at work.

Q: Will they put any kind of sticker, sign or poster on my house so others know I may have been exposed and should be quarantined?


Your information is confidential. Your name will not be released to your contacts or your COVID-19 status – that information will only be known to public health officials and local health department partners, if needed.

Q: Will NJ allow other third-parties to access the information? If so, which ones and for what purposes?

No. Third-parties will not have access to the personal information you share.

We have placed strict limits on the contact tracing program – we collect limited data (only what is needed to keep you and your close contacts safe), use it for limited purposes (stop the spread of COVID-19), and limit who it is shared with (public health officials and our local partners).

Q: How did a contact tracer get my name and phone number?

Contact tracers are calling individuals who have tested positive for COVID-19 or may have come in close contact with someone who tested positive for COVID-19.

Individuals who tested positive for COVID-19 work with a contact tracer to list all of their close contacts – anyone who was within six feet of them for more than 10 minutes starting two days before they first had symptoms.

The COVID-19 positive individual then gave your number to a contact tracer, so they could reach out solely for the purposes of letting you know about the risk to you and the need to self-quarantine. This will help limit exposure to your family and others if you develop symptoms.

Q: How will I know if the person calling me is an official contact tracer and not a scam? Is there a way to verify it is not a scam?

Contact tracers will reach out via phone, text message, or letters dropped off at your door. Contact tracers will provide their name, agency, and a phone number.

When a contact tracers reaches out, it is to let you know about the risk to you and your family and what you can do to protect your loved ones and community.

A contact tracer will never ask for your social security number. A contact tracer will never ask for confidential financial information like your bank or credit card number.

A contact tracer will never ask about your immigration status and ICE will not be notified about your location.

If someone is requesting personal information covered above, it is likely a scam. You can report these calls online to the New Jersey Division of Consumer Affairs or by calling 973-504-6240.

If you have any doubts about the legitimacy of your conversation with a contact tracer, you may hang up and call your local health department. You should also feel free to request the name and ID of anyone who calls.

You can find your local health department's contact information through the Department of Health's directory.

Q: Is my cell phone being tracked or my GPS location followed?

No. An individual's cell phone is never tracked, a GPS location is not followed, and geolocation data is not collected or used.

Contact tracing relies on individuals sharing who they may have come into close contact with and who may have been infected with COVID-19.

Q: What about the COVID Alert NJ app? How is that different from contact tracing?

Contact tracing is a decades-old common practice in public health. It is not the same thing as "exposure notification" or "digital alerting" tools. These consumer apps, such as those created with Google and Apple's API like COVID Alert NJ, are not contact tracing tools. These apps function as a way for the public to track if they have come into contact with a person who has tested positive and entered that information into their phone.

COVID Alert NJ is New Jersey's free and secure mobile app that anonymously alerts users if they have been in close contact with someone who has tested positive for COVID-19. The app is an additional tool in New Jersey's efforts to fight the spread of COVID-19.

COVID Alert NJ does not use, track, or collect any geolocation or GPS data. It works exclusively through Bluetooth proximity detection. Alerts do not share the identities of other users to one another, the New Jersey Department of Health, or any other entity. The app does not collect or store personal information including name, date of birth, address, phone number, email address or location in order to show exposure notifications.

Q: Will I be asked about my immigration status and will ICE be notified about my location?


You and the information you share will not be used for the purposes of law enforcement or immigration enforcement in any way. In addition, it will not negatively affect your public charge assessment or be used to deny access to health care or any other essential service.

Q: Can my employer fire me if I was told to quarantine and am not able to go to work?

On March 20, 2020, Governor Murphy signed a law that prohibited an employer from firing or otherwise punishing an employee who requested time off or took time off from work based on a medical professional's determination that the employee had, or was likely to have, COVID-19.The law has expired and only applies to actions taken during the public health emergency, from March 20, 2020 through June 4, 2021.

If you are currently unable to work due to COVID-19 or must take care of a loved one or a child, you may use earned sick leave.

NJ employers of all sizes must provide full-time, part-time, and temporary employees with up to 40 hours of paid sick leave per year so they can care for themselves or a loved one, including for COVID-19 testing, illness, quarantine, or vaccination.

In addition, depending on your situation, you may be eligible for Temporary Disability Insurance or Workers' Compensation. To learn more, refer to the NJ Department of Labor's COVID-19 Worker Benefits and Protections page.
