Testing for COVID-19

Sheridan County Public Health does not conduct COVID-19 testing. Below are your options for testing for COVID-19.

Test at home
Wyoming offers free at-home COVID-19 testing through a company called Vault. These tests are available to Wyoming residents at no cost; insurance is not necessary. For this test, saliva is collected during a supervised, online telehealth visit with a Vault test supervisor, which requires an internet connection. Learn more and order your test on the Wyoming Department of Health’s dedicated testing webpage.

In-person testing options
Testing is available at some private healthcare providers, hospitals and some pharmacies. We are aware of the following locations:

Please call ahead to make an appointment and/or follow the location’s precautionary measures to test safely.

Positive tests results from all locations are reported to the local Pubic Health office for contact tracing.

Testing Children 18 years of age & Younger
Please contact your pediatrician if your child has been in close contact with a COVID-19 positive individual or if you suspect they are ill.

Businesses & Organizations: Obtaining Tests
The Wyoming Department of Health is offering free COVID-19 testing to businesses and organizations in Wyoming. Tests are available on a first come/first served basis as supplies are limited. Go to to order.

Contact Tracing

Sheridan County Public Health is prioritizing contacting laboratory-confirmed individuals who are 65+ years of age, as their age may increase their risk of serious illness.

Attempts are made to text all other laboratory-confirmed individuals. Individuals who test positive are encouraged to reach out to those they have been in close contact with to inform them of their increased risk of contracting COVID-19.

If you test positive for COVID-19 and are experiencing severe symptoms, call 911. If you have questions about quarantine and isolation, please contact Sheridan County Public Health at 307-672-5169.

About Contact Tracing

Also known as case investigation, contact tracing involves Public Health or trained personnel to work with a person who has been diagnosed with COVID-19 (symptomatic and asymptomatic) to identify and provide support to people (contacts) who may have been infected through exposure to the patient.

Contact tracing helps protect you, your family, and your community by letting people know they may have been exposed to COVID-19, helping people who may have been exposed to COVID-19 get tested, and asking people to self-isolate if they have COVID-19 or self-quarantine if they are a close contact. This process prevents further transmission of disease by separating people who have (or may have) an infectious disease from people who do not.

Close Contact
The Center for Disease Control and Prevention (CDC) and Wyoming Department of Health (WDH) use a combination of both proximity and time to define close contact. You are considered at highest risk for having been exposed to the virus if you meet the following criteria:

  1. Closer than 6 feet to a positive AND
  2. For longer than 15 minutes cumulative AND
  3. The contact happened during the positive individual’s exposure period. This includes:
    1.  The 48 hours prior to symptom onset or 48 hours prior to the date of the positive test if no symptoms are present.
    1. The entire length of time the person is symptomatic or 10 days from the date of a positive test if no symptoms are present

Both mean you need to stay home. Isolation is used for the person who tested positive for COVID-19 and guides individuals to stay away from others in the household. Quarantine is used for close contacts and has less restrictive guidelines.
