New York, once an epicenter of the coronavirus pandemic, is further tightening its restrictions on visitors from the current hot spots across the country. Starting today, travelers from 19 states must fill out a health form or face a stiff penalty.

The form is Gov. Andrew M. Cuomo’s latest effort to better trace travelers who may have the virus, and to fend off a possible second wave of infections in New York. (On Monday, he illustrated just how far the state has come by showing this quirky poster.)
Since late June, travelers from several states, including Texas and Florida, have been required to quarantine for 14 days upon arrival in New York. But it’s still unclear how officials can enforce the isolation period.

Here’s what else you need to know:

The details
Travelers from the 19 states must provide their contact information and planned whereabouts to the authorities upon arrival at airports across New York State.

If passengers don’t complete the form, they can be given a summons and fined up to $2,000. They can also be brought to a hearing and ordered to complete the quarantine. In New York City, the Port Authority of New York and New Jersey will enforce the new rule, Mr. Cuomo said. But once travelers leave the airport, they can go wherever they want, whenever they want. Also, the many people who enter the state by other means of transport, like cars and trains, must fill out the form online. That means much of the compliance will be left to the whims of the travelers, my colleagues Luis Ferré-Sadurní and Nate Schweber wrote.
