Marin Aligns with Updated CDPH Isolation & Quarantine Guidance

California Department of Public Health recently updated its guidance for Isolation and Quarantine for the general public. These updates are in response to increased immunity within our community, and the evolution of the virus itself. 

The following is a summary of changes to this guidance: 

  1. Quarantine recommendations have been removed for those who have had a COVID-19 exposure and are asymptomatic. The SARS-CoV-2 virus which causes COVID-19 has evolved to a shorter incubation period (e.g., an average of 2-3 days). This shorter time frame has often already ended by the time someone is notified of their close contact status therefore the critical quarantine timeframe has passed. This applies to all persons in the general public, regardless of vaccination status. Should symptoms develop, the individual should stay home and get tested

  1. The definition of “close contact” has been expanded to include shared indoor airspace (e.g., home, clinic waiting room, airplane etc.), for a cumulative total of 15 minutes or more over a 24-hour period with a covid-positive person during their infectious period. 

  1. The definition of “infectious period” has been updated: 

  • For symptomatic infectious persons:  
    The infectious period is 2 days before the infected person had any symptoms through Day 10 after symptoms first appeared (or through Day 5 if testing negative on Day 5 or later), and 24 hours have passed with no fever, without the use of fever-reducing medications, and symptoms have improved, OR 

  • For asymptomatic infectious persons: 
    The infectious period is 2 days before the positive specimen collection date through Day 10 after positive specimen collection date (or through Day 5 if testing negative on Day 5 or later) after specimen collection date for their first positive COVID-19 test. 

  1. In certain high-risk settings, work exclusion or restriction are recommended if the individual exposed is unvaccinated or incompletely vaccinated, and was not previously infected with SARS-CoV-2 within the prior 90 days.  

NOTE: This updated guidance is for the general public only and does not apply to schools or healthcare personnel in certain settings.
