    (CNN) — With cases of Covid-19 now past the 25 million mark in the United States, some states have updated their rules and regulations in the new year.

If you wish to travel to another state, it is important to be updated on the latest statewide regulations. While some US states still have no restrictions on leisure travel, all their official websites have important Covid-19 safety information, including possible face mask mandates in public settings.

This list is alphabetical and includes links where you should get more information and updates before you head out:

Alabama

UPDATE: As of January 25, 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. You can check here for updates.

Alaska

Visitors to Alaska should have a “qualifying Covid-19 test within 72 hours of departure” and upload their negative result to a Travel Declaration Form. You’re then asked to observe strict social distancing for five days. A second test is suggested — but not required — between days 5 and 14. If you don’t arrive with a negative Covid-19 result, you must take a Covid-19 test at the airport for $250 and quarantine at your own expense until you get the results. Check here for details and updates.

Travelers heading to Hawaii must upload their negative test result to the Safe Travels system prior to departure or, as an alternative to uploading, bring a hard copy of their negative test result with them when boarding their flight.” The test must be taken within 72 hours of the final leg of departure.
