Being a “secondary contact” does not require you to be quarantined under current CDC guidelines. You would only be required to quarantine if you have had close contact with someone diagnosed with a presumptive or confirmed case of COVID-19. You should inform HR/Risk if someone in your household is ordered to quarantine.
You should do your best to avoid close contact with the exposed person for the duration of their quarantine because there is a possibility that they may not develop symptoms, but still be contagious as a carrier for the virus.
Monitor yourself for symptoms and regularly clean frequently touched surfaces. You can still report to work following the CDC’s Safety Practices for Critical Infrastructure Workers Who May Have Had Exposure to a Person with Suspected or Confirmed COVID-19.
If you do notice symptoms, contact your primary health care provider, notify your supervisor/manager, and stay home. DO NOT report to work if you have symptoms.
