On December 26, 2020, the New York State Department of Health (DOH) updated its mandatory quarantine requirements (the Quarantine Advisory) for people who have been exposed to COVID-19 but do not develop symptoms. The Quarantine Advisory may be found here. Previously, asymptomatic individuals who had been exposed to COVID-19 had to quarantine for 14 days. Now, such individuals must quarantine for 10 days. Note that the Quarantine Advisory also applies to individuals who traveled to a non-border state or country.
