COVID-19: Updated Quarantine Options

CDC shortens recommended isolation and quarantine period for those who are asymptomatic

December 28, 2021 CDC has shortened the recommended isolation time for people with COVID-19 who are asymptomatic, from 10 days to five days, followed by five days of wearing a mask when around others. If the positive person cannot wear a mask, then they should stay home for the second five-day period.

Regardless of the quarantine period length, people should continue to monitor their symptoms for 14 days.

Anyone who would have symptoms in the 14 days would still be considered to be a probable case and would need to follow isolation guidance.


Guidance for those who are fully-vaccinated

Definition of fully-vaccinated – this means that two weeks or more have passed since receiving the second dose in a two-dose series (Moderna and Pfizer) or two weeks or more have passed since receiving one dose of a single-dose vaccine (Janssen/Johnson & Johnson)

Fully-vaccinated persons with an exposure to someone with suspected or confirmed COVID-19 are advised to:

  • Be tested 5-7 days after exposure
  • Wear a mask in public indoor settings for 14 days or until they receive a negative test result.
  • Monitor for symptoms of COVID-19 for 14 days following the exposure
  • Follow recommended isolation protocols if they develop symptoms of COVID-19


However, they are not required to quarantine if they meet the following criteria:

  • They are fully-vaccinated with a vaccine currently authorized for emergency use by the U.S. Food and Drug Administration or the World Health Organization
  • Have remained asymptomatic since the current COVID-19 exposure
