COVID-19 can easily spread between people who are in close contact with one another. To help slow COVID’s spread, protect vulnerable individuals, and prevent the healthcare system in the County of Marin from being overwhelmed, it is necessary for people who have been infected to isolate, and people who have been exposed to a person who has an active COVID infection will need to quarantine.
Isolation separates sick people and those who have tested positive with COVID from people who are not sick.
If you have tested positive for COVID you should isolate.
If you received a positive result for your COVID test, your doctor or clinic that provided your results will inform Public Health, there is no need to you inform the county.
Quarantine separates and restricts contact with others, for people who were exposed to COVID, to see if they become sick. Someone who may have been exposed to COVID but does not know it, or they may have the disease but do not show symptoms.
If you have NOT been fully vaccinated, and you have been in "close contact" with people who have tested positive for COVID,
you NEED to quarantine.
Close contact means you have been exposed to someone with active COVID infection for over 15 minutes in a 24 hour period, or had contact with them when no masks were worn. The exposure may happen with:
- any household member
- individuals that have shared a home within 10 days of a person's COVID-19 diagnosis
- intimate partners
If you've been fully vaccinated, or meet all of the following criteria, and you’ve been around someone who has COVID-19, you do not need to stay away from others.
- Someone who has COVID-19 illness within the previous 3 months; AND
- Has recovered; AND
- Remains without COVID-19 symptoms (for example, cough, shortness of breath)
However, fully vaccinated people who have come into close contact with someone with suspected or confirmed COVID-19 should be tested 3-5 days after exposure, and wear a mask in public indoor settings for 14 days or until they receive a negative test result.
