(CNN) — With cases of Covid-19 beyond the 28 million mark in the United States, some states have updated or expanded their travel rules and regulations in 2021.
While some US states still have no restrictions on allowing leisure travel, all their official websites have important Covid-19 safety information. For instance, most states have mandates on face masks in public settings.
This list is alphabetical and includes links to state websites that have important details you should read before you cross state lines:
As of February 23, there were no statewide travel restrictions in Alabama. However, visitors should be aware of the state's mask mandate, as it applies to travelers, too. It's effective through March 5 (though it's been extended numerous times). You can check here for updates.
UPDATE: Visitors to Alaska are no longer required to have a negative result from a Covid-19 test to enter. Gov. Mike Dunleavy said the state's emergency Covid-19 declaration has been allowed to expire, according to a news release from the governor's office.
