Quarantine Guidelines

Asymptomatic individuals who have been fully vaccinated against COVID-19 do not need to quarantine after exposure to COVID-19. Fully vaccinated is defined as being 2 weeks or more after either receipt of the second dose in a 2-dose series, or 2 weeks or more after receipt of one dose of a single-dose vaccine.

Asymptomatic individuals exposed to COVID-19 who have been previously diagnosed with laboratory confirmed COVID-19, and have since recovered, are not required to retest and quarantine within 3 months after the date of symptom onset from the initial COVID-19 infection or date of first positive diagnostic test if asymptomatic during illness.

Asymptomatic domestic travelers coming to New York State are not required to quarantine, however quarantine is still recommended for domestic travelers, consistent with CDC guidance for international travel, for either 7 days with a test 3-5 days after travel, or 10 days without a test.

Individuals who have been exposed to someone with confirmed or suspected COVID-19, who are not fully vaccinated or have not recovered from COVID-19 in the previous 3 months, are required to quarantine for 10 days after exposure. Testing is not required to end quarantine if no symptoms have been reported during the quarantine period. However, a test should be sought immediately if any symptoms develop during the 14 days after exposure.

Irrespective of quarantine status, all individuals exposed to COVID-19 must:

  • Monitor symptoms daily from day of exposure (or first date of awareness of exposure if there is a delay) through Day 14;
  • Continue strict adherence to all recommended non-pharmaceutical interventions, including hand hygiene and the use of face coverings, through Day 14 (even if fully vaccinated);
  • Immediately self-isolate if any symptoms develop and contact the Suffolk County Department of Health Service or their health care provider to report this change in clinical status and determine if they should seek testing.

  • Mandatory Quarantine

    1. Person has been in close contact (6 ft.) with someone who is positive but is not displaying symptoms for COVID-19.
    2. Person has traveled to another country.

    Mandatory Isolation

    1. Person has tested positive for COVID-19, whether or not displaying symptoms for COVID-19.
    2. The Suffolk County Department of Health Services must immediately issue an order for Mandatory Quarantine or Isolation once notified, which shall be served on the person impacted.

    Precautionary Quarantine

    - Person meets one or more of the following criteria:

    1. Proximate exposure to a positive person but has not had direct contact with a positive person and is not displaying symptoms.

    Any person the Suffolk County Department of Health Services’ believes should be quarantined that is not addressed through the interim guidelines, should contact the New York State Department of Health.
