On Monday, Gov. Andrew Cuomo signed an executive order reminding international travelers entering New York from Level 2 and 3 countries to quarantine and fill out the NYS Department of Health traveler health form to further prevent the spread of COVID-19 as countries across the globe experience alarming second waves of the virus.

Since March, New York State has required a mandatory quarantine for any traveler entering New York from a Level 2 or Level 3 country - that's all but 31 countries on the globe. Cuomo's announced is a direct response to the CDC's decision to roll back COVID-19 screening measures at airports.

"The CDC's decision to end enhanced screening at airports, coupled with alarming case increases in countries around the world, presents an increased threat to New York's progress in the war against COVID-19," Cuomo said. "Today's Executive Order will require the Department of Health to alert all travelers from any Level 2 or Level 3 country of mandatory quarantine requirements, as well as require international travelers to complete the DOH Traveler Health Form to aid in the state's robust contact tracing efforts and further prevent the spread of COVID-19."

Since the CDC has continued to roll back their screening measures at airports accepting international flights, this measure is necessary to link travelers to the appropriate local Department of Health for contact tracing purposes, according to Cuomo's office.
