Corrections: Dec. 16, 2021

A2-A3

A Here to Help item on Sunday about navigating travel restrictions during the holiday season misstated the number of U.S. states that have domestic travel requirements. American travelers wishing to enter Hawaii must show proof of vaccination, a negative test result or they must quarantine for 10 days; it is not the case that there are no vaccine, testing or quarantine requirements to travel within the United States.
