Stay home.

If you have had close contact with someone who has COVID-19, you may be required  (per NAC 441A.280) to maintain quarantine (stay home and away from others) as outlined below.

  • People who are unvaccinated should quarantine for 5 days followed by strict mask use around others for 5 more days.
  • People who are more than six months out from their last dose of Pfizer or Moderna vaccine (or more than two months after receiving the Johnson & Johnson vaccine) and have not yet received a booster dose should quarantine for 5 days followed by strict mask use around others for 5 more days. If a 5-day quarantine is not possible, the exposed person must wear a well-fitting mask around others for 10 days.
  • Individuals who have received a booster dose do not need to quarantine following an exposure but should wear a mask around others for 10 days.

After exposure to someone with COVID-19, it is recommended to get tested 5 days after exposure. If symptoms develop at any time, you should immediately quarantine until a negative test result determines your symptoms are not related to COVID-19.

After your quarantine period you should continue to limit your contact with others as much as possible, and always wear a face mask when you are around people who do not live with you.

  • You were within 6 feet of someone who has COVID-19 for a total of 15 minutes or more, either during one 15-minute block of time or cumulatively throughout a given day

  • You had direct physical contact with the person (hugged or kissed them)
  • You shared eating or drinking utensils
  • They sneezed, coughed, or somehow got respiratory droplets on you
  • Stay home. Do not leave your home, except to get medical care. Do not visit public places or other people’s homes and do not invite anyone to your home.
  • If you need medical carecall ahead to let your provider know you have been exposed to COVID-19.
  • Use grocery delivery or curbside services.
  • Stay in a specific room and away from other people and pets in your home as much as possible. Use a separate bathroom, if available.
  • Avoid sharing personal items with other people in your household, like dishes, towels, and bedding.
  • Take everyday actions to prevent the spread of germs.
    • Clean your hands often with soap and water for at least 20 seconds, or use an alcohol-based hand sanitizer that contains at least 60% alcohol.
    • Cover your cough/sneeze.
    • Avoid touching your eyes, nose, and mouth.
  • Clean all surfaces that are touched often like counters, tabletops, and doorknobs. Use household cleaning products according to the label instructions.
  • Make the best of your time at home by teleworking if you’re able or catching up on reading, your favorite shows, or other at-home hobbies.
  • Keep in touch with your family and friends by telephone or video calls. 

According to CDC, if you do not have any symptoms AND you have a negative COVID-19 test 5 days after you were exposed, you may end quarantine 7 days after you were exposed. You must monitor for symptoms for the full 14 days.

Monitor your symptoms for 14 days after your exposure.

If you develop symptoms at any time, continue to separate yourself from others and get tested.

Stay home, wash your hands frequently, wear a mask and stay at least 6 feet away from others. Follow the guidance for people who have tested positive or have symptoms of COVID-19.

If you need medical care, make sure to let your provider know you are experiencing symptoms and had contact with someone who tested positive for COVID-19.

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.

Beware of fraudulent messages. Valid Health District emails are from and text messages are from 1–844–990–0029. The Health District will never ask for your Social Security Number, citizenship, credit card, or bank information.

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.

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.

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.

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 at the top of this page. If you develop symptoms, get tested.
