Travelers from three more states are required to quarantine for two weeks when they enter Connecticut, New York and New Jersey.
Delaware, Kansas and Oklahoma are the most recent additions to the travel advisory.
The full list now includes 19 states that have high coronavirus infection rates above 10%.
Connecticut Governor Ned Lamont, speaking at an event in New Haven on Tuesday, said for the first time in months Connecticut has had a day with no COVID-19-related fatalities.
“Zero related fatalities. And I have said that’s thanks really to each and every one of you. You are wearing the masks. You take the protocols seriously.”
New York Governor Andrew Cuomo said the tristate area wants to keep down their rates of COVID-19 hospitalizations, cases and deaths, after several months of what he calls “hell.”
New York has remained at its lowest levels since the peak of the virus in April, with 800 deaths and thousands of new cases per day.
Florida, now hard hit by the virus, reported 12 times as many new cases as New York at last count. New Yorkers who travel to high infection states will also have to quarantine. State workers could even be denied paid sick leave for voluntary travel there.
States will be removed from the quarantine list when their numbers improve.
