If an individual meets any of the following criteria, they should self-quarantine/isolate in their home for 14 days.
- If anyone in the household is being tested for COVID-19 through either the Missouri State Public Health Laboratory or a private laboratory, everyone in the household should remain home while the test results are pending.
- If anyone in the household has been diagnosed with COVID-19 through a lab confirmed test, everyone in the household should remain quarantined for 14 days from their last exposure.
- If an individual has had close contact with someone that is symptomatic and is being tested for COVID-19, that individual should remain home while results are pending. If there is high suspicion for positive results and spread, PCHD may decide contact investigation needs to be started sooner but will be determined on a case-by-case basis.
- If an individual has had close contact with someone that is symptomatic and has been diagnosed with COVID-19 through a lab confirmed test, that individual should remain quarantined for 14 days from their last exposure.
No special considerations, including home quarantine, are recommended for people exposed to asymptomatic people with potential exposures to COVID-19 (such as in a household), i.e. “contacts of contacts”. These people are not considered exposed to COVID-19.
As of April 9, 2020 CDC issued new Guidance for Implementing Safety Practices for Critical Infrastructure Workers Who May have had exposure to a person with suspected or confirmed COVID-19. To ensure continuity of operations of essential functions, CDC advises that critical infrastructure workers may be permitted to continue work following potential exposure to COVID-19, provided they remain asymptomatic and additional precautions are implemented to protect them and the community.
