(CNN) — With the Covid-19 pandemic in near constant fluctuation in the United States, the 50 states are having to adapt rapidly with their rules and regulations. If you're planning a family vacation or simply wish to travel to another state, it is important to be updated on the latest statewide regulations. While some US states have no restrictions on travel, all their sites 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:

Alaska's latest travel protocols have been in effect since August 11. Visitors from other states must do one of the following:
-- Submit a travel declaration and self-isolation plan online and arrive with proof of a negative Covid-19 test.
-- Follow a plan that your employer filed with the state if you come for work.
-- Buy a $250 Covid-19 test when you arrive and self-quarantine at your own expense until you get the results.
Alaska residents also have protocols they must follow for travel.
According to the CDC, "people in quarantine should stay home, separate themselves from others, monitor their health, and follow directions from their state or local health department." Leaving your home state to enter a state with a mandatory quarantine means you need one place to stay and to stay put. Check here for Alaska details and updates.
