What is contact tracing?

Contact tracing involves finding people who may have been exposed to COVID-19 and asking them to stay separate from other people (that is, to quarantine) until it is certain they did not become infected.

How does contact tracing work at the Southern Nevada Health District?

1. The Health District is notified about positive COVID-19 tests and people diagnosed with COVID-19.
Health care providers and laboratories are required by Nevada state law (NAC441A.230 and NAC441A.235) to notify the Health District when someone tests positive or might have COVID-19.

2. The Health District gets in touch with people who have COVID-19.

People who have COVID-19 are required to give the Health District the name and contact information of everyone they had close contact with during a certain time period.

There are two ways the Health District gets in touch with people who have COVID-19:

  • A public health worker calls the person.
  • The Health District sends the person who has COVID-19 an automated email or text message with a link to an online portal.

*All information shared with the Health District is confidential.

More information for people who have COVID-19 can be found here.

3. The Health District gets in touch with people who have had close contact with someone who has COVID-19.

The Health District notifies people that they have had close contact with someone who has COVID-19 using an automated email and text message system.  

People who have COVID-19 are also encouraged to tell anyone they had close contact with that they tested positive. More information for people who tested positive can be found here.

*The Health District cannot say who the person has had contact with, only that contact occurred and the date it happened.

What is the COVID Trace app?

COVID Trace is a free, easy to use mobile phone app that allows people who have COVID-19 to notify others that they may have been exposed—even if the person who has COVID-19 does not know the other person. It is anonymous, and your privacy is protected.

The Southern Nevada Health District uses an automated messaging system to send messages to people who have COVID-19 and those who have been exposed. The COVID Trace app is separate from this messaging system.

For the COVID Trace app to work, you must enroll before you test positive for COVID-19. If you have already enrolled in the app when you test positive for COVID-19, a Contact Tracer will provide a verification code when they call you. You can use the code to anonymously alert other COVID Trace app users you have been in close contact with that they might have been exposed to COVID-19.

How can I be sure that an email or text message is from the Southern Nevada Health District?

Beware of fraudulent messages. Valid automated messages from the Health District are from:

  • Email: do-not-reply@snhd.org
  • Text message: 1–844–990–0029.

The Health District will never ask for your Social Security Number, citizenship, credit card, or bank information.

I received an email or text message telling me I have an important notification from the Southern Nevada Health District.

The Health District tries to notify everyone who has tested positive for certain conditions, including COVID-19, through an automated email and text messaging system. To protect your privacy, the Health District does not share personal health information over email or text message. Instead, you will be provided with a link to log on to an online portal where you can view your notification.

If you received a message from us, please follow the link to view the notification and fill out the survey. The information you provide helps the Health District protect the health and well-being of the community. All information is kept confidential.

I did NOT receive an email or text message telling me I have an important notification from the Southern Nevada Health District.

Sometimes the Health District does not have an accurate email address or cell phone number for people who test positive for certain conditions, including COVID-19. In this case, our automated message cannot be delivered.

If you have tested positive or if you have symptoms of COVID-19, you are still required to self-isolate—even if you did not receive a notification from us. Please use the information on this page to find out when you can end self-isolation and what else is required from you.

I received an email or text message telling me I’ve been exposed to someone with COVID-19.

People who test positive for COVID-19 are required to tell the Health District about all people they have had close contact with while they are contagious. The Health District tries to notify everyone who has been exposed to someone who tested positive through an automated email and text messaging system.

If you received a message from us, please maintain quarantine until the date in your message. Monitor for symptoms and use the information and resources on this page.

I did NOT receive an email or text message telling me I’ve been exposed to someone with COVID-19.

Sometimes close contacts are not reported to the Health District or there is a problem with the phone number or email address and our automated message cannot be delivered.

If you know you have been exposed or think you might have been exposed to someone with COVID-19, you are still required to maintain quarantine—even if you did not receive a notification from us. Please use the information on this page to find out when you can end quarantine. 

I received a notification through the COVID Trace mobile app that I have been exposed to someone who has COVID-19.

If you received a notification through the app telling you that you have been exposed to someone with COVID-19, you must maintain quarantine as described here. If you develop symptoms, get tested.
