All arrivals from outside the state will have to undergo a rapid test at the airport or go into 10-day quarantine. That’s in addition to the required test 72 hours prior to travel, and regardless of vaccination status (even as the state has discussed proof of vaccination in lieu of testing).
The specific date this will begin hasn’t announced yet, noting that it will take ‘at least 10 working days’ to get the program up and running, but it’s expected to start prior to end of April.
