Isolation and Quarantine for COVID-19

Library Description

COVID-19 can easily spread between people who are in close contact with one another.  To help slow COVID-19’s spread, protect vulnerable individuals, and prevent the healthcare system in the County of Marin from being overwhelmed, it is necessary for Marin Public Health isolate persons with COVID-19 and quarantine persons exposed to someone with COVID-19.


What is the difference between isolation and quarantine?

Isolation and quarantine are public health practices used to protect the public by preventing exposure to people who have or may have a contagious disease.

  • Isolation separates sick people with a contagious disease from people who are not sick.
  • Quarantine separates and restricts the movement of people who were exposed to a contagious disease to see if they become sick. These people may have been exposed to a disease and do not know it, or they may have the disease but do not show symptoms.


How do I know if I should isolate or quarantine?

You should isolate or quarantine if...

  • you have tested positive for COVID-19
  • you have been in "close contact" with people who have tested positive for COVID-19.  Close contact means:
    • any household member
    • individuals that have shared a home within 14 days of a person's COVID-19 diagnosis
    • intimate partners
    • caregivers
    • someone who was within six feet of an infected person for 15 minutes or longer.

If you believe you meet the criteria above, please review the COVID-19 Guidance for At Home Quarantine & Isolation Safety.
