Colorado has been added to a pandemic travel advisory for entering Connecticut, New York and New Jersey. Arizona and Virginia were removed after COVID-19 infection rates dropped.
Anyone traveling to Connecticut from a listed state can show proof of a negative coronavirus test, or will have to quarantine for 14 days upon arrival. New York does not accept negative test results and requires a two week isolation.
Now, 32 states and one territory are on the travel advisory list because of high rates of COVID-19 infections.
