When to Test for COVID-19

Updated July 28, 2021 - While fully vaccinated individuals still do not need to quarantine after an exposure, CDC now recommends fully vaccinated people be tested 3-5 days following a known exposure to someone with suspected or confirmed COVID-19 and wear a mask in public indoor settings for 14 days or until they receive a negative test result. Fully vaccinated people who live in a household with someone who is immunosuppressed, at increased risk of severe disease, or unvaccinated (including children <12 years of age) could also consider masking at home for 14 days following a known exposure or until they receive a negative test result. Most fully vaccinated people with no COVID-like symptoms do not need to quarantine or be restricted from work following an exposure to someone with suspected or confirmed COVID-19 if they wear a mask in public indoor settings for 14 days after exposure or if they receive a negative test result from a test taken 3-5 days after exposure. They should isolate if they test positive.


‘Close Contact’ (Known Exposure) - Symptoms

If you have had close contact (> 15 minutes, < 6 feet) with someone known to have tested positive for COVID-19 and you currently HAVE symptoms, please test immediately and quarantine yourself from others immediately. Please click ‘Testing Options’ to schedule a test.


If you have immediate questions please call our COVID hotline at 307-732-8628 and one of our nurses will return your call.


If you are having a medical emergency, please call 911 and let them know that you have been exposed to someone who has tested positive to COVID-19.


'Close Contact’ (Known Exposure) - No Symptoms

If you have had close contact (> 15 minutes, < 6 feet) with someone known to have tested positive for COVID-19 and you currently have no symptoms, please wait to test until at least 5 days from your last contact with the person who tested positive. 


The Teton County Public Health Department (TCHD) Isolate & Trace Team will contact you IF you were identified as a close contact by the positive case during the interview. This discussion with TCHD will assist you with testing and quarantine. If you are not contacted by the team in several days (timing depends on receipt of positive result to TCHD), please call the COVID hotline (307-732-8628) to explain the situation and that you think you are a contact so we may help you.


Please note that when individuals test too early, levels of the virus in the body may be low and undetectable (at that moment) but building, leading to a false sense of security. Close contacts may develop symptoms and become infectious after testing negative. Testing on or after day 5 gives the TCHD greater confidence in the test result.


Testing exemption: ‘Close Contact’ (Known Exposure)

  1. If you are ‘fully vaccinated’ (fully vaccinated = +2 weeks past last dose in 2 dose series or +2 weeks past single dose vaccination); unless you live in a congregate living setting. 

  2. If you have tested positive in the past 90 days

If either of these conditions are present, only test if you  have or develop symptoms. 


Not a ‘Close Contact’ (No Known Exposure) - HAVE Symptoms

If you have any symptoms of COVID-19 regardless of your vaccination status, please test and self quarantine at home. If you have had no known contact with someone who tested positive you can end your self quarantine period once you have a negative test result and you feel well enough to resume regular activities. If your symptoms worsen or change after receiving a negative test result, please contact the Teton County Health Department at 307-732-8628 or your primary care provider to see if testing again is appropriate.  Symptoms of COVID
