CDC Shortens Recommended COVID-19 Isolation and Quarantine Periods

On December 27, 2021, the US Centers for Disease Control and Prevention (CDC) revised recommendations for people who test positive for or are exposed to COVID-19. The updated guidelines reflect recent evidence that transmission of the now-prevalent Omicron variant typically occurs 1-2 days prior to the onset of symptoms and 2-3 days after. The recommendations are also aimed at returning people to work as quickly and safely as possible in the face of nationwide staffing shortages. The CDC’s updated recommendations provide:

After positive COVID-19 test (regardless of vaccination status) Isolate at home for 5 days

If you have no symptoms or symptoms have fully resolved after 5 days, you may leave your home but continue to mask for 5 more days.

After COVID-19 exposure for people who are not vaccinated or who are more than 6 months out from their second dose of vaccine and not yet boosted Quarantine for 5 days and then mask for 5 more days

If quarantine is not feasible, mask for 10 days.

Note: the day of exposure is considered day zero (0)

After COVID-19 exposure for people who are boosted or completed the primary Pfizer or Moderna vaccine series within the last 6 months, or who completed the J&J vaccine series within the last two months Mask for 10 days

Note: the day of exposure is considered day zero (0)

After COVID-19 exposure (regardless of vaccination status) If possible, take a COVID-19 test on day 5 following exposure.

If you develop symptoms at any time during the quarantine or masking period, get a test and begin isolation at home.

Note: the day of exposure is considered day zero (0)

The new CDC recommendations should provide some relief to the many US employers dealing with staffing challenges related to COVID-19.
