Travelers from Missouri, Oregon and Washington do not need to be quarantined upon arrival in Massachusetts, the state said on Friday.

The three states have been classified as lower risk by Massachusetts officials and, along with Hawaii and Puerto Rico, are on the list of places where travelers do not need to be quarantined for 10 days upon arrival. The change will take effect just after midnight on Saturday, according to the state’s website.

Currently, those arriving in Massachusetts must be quarantined unless they meet the State criteriaThis includes getting out of a lower risk state, having a negative COVID-19 test or going through the state within 72 hours of your arrival.

Also on Friday, Maine Governor Janet Mills announced that those traveling to the state from Massachusetts, Connecticut and Rhode Island can now visit without quarantining or taking a negative COVID-19 test.

Mills announced this while detailing some of the backward steps in COVID-19 measures as vaccinations increased in the state. The move is ahead of summer, a season she described as “a crucial time of the year for so many businesses and for the economy of our state as a whole”.

Previously, among New England travelers, only New Hampshire and Vermont people were quarantined or tested negative for COVID-19 for 10 days. The change announced on Friday means people from all states of New England can travel freely to Maine. The measure also applies to people from all states who have been fully vaccinated or have recently had COVID-19 and have recovered, Mills said.

On May 1, Maine will lift its restrictions even further, allowing people from any state to visit without quarantining COVID-19 or doing negative tests, except those from states that have been approved by officials from public health is found to be at high risk.

“If one or more states see an increase in highly contagious COVID-19 variants, Maine will apply its testing or quarantine requirement to travelers in and out of that state,” the state website said. “The Maine CDC will publicly announce such states when they are identified.”

Mills also announced that the state is easing capacity limits for indoor and outdoor gatherings. Indoor gatherings are currently limited to 50 people and outdoor gatherings are limited to 100 people. On March 26, the state will switch to a percentage model and the limits for indoor collection will be raised to 50 percent of the permanent capacity of a venue. Assuming “all goes well,” Mills said, that will increase to 75 percent on May 24th.

For outdoor gatherings, the capacity limits will be increased to 75 percent on March 26th and lifted entirely on May 24th.

Bars and tasting rooms will also be open for indoor service on March 26, Mills said.

Mills said the state will adjust capacity limits depending on key COVID-19 measures.

The state’s mask mandate remains in place, and Mills encouraged residents to continue to take mitigation measures such as distancing.

On Thursday, Connecticut Governor Ned Lamont announced As of March 19, the state’s mandatory 10-day quarantine or negative test result will become an indicator for arriving travelers, meaning the measure is recommended, but those who fail to comply will not be penalized.
