Gov. Phil Murphy has announced that two more states have been added to the COVID-19 travel advisory lists, bringing the count to 39 states and two territories.

California and Massachusetts have now been added after a spike in COVID-19 cases. Those states now join Alabama, Alaska, Arizona, Arkansas, Colorado, Florida, Georgia, Guam, Idaho, Iowa, Indiana, Illinois, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Missouri, Mississippi, Montana, North Carolina, North Dakota, Nebraska, New Mexico, Nevada, Ohio, Oklahoma, Puerto Rico, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, Wisconsin, West Virginia and Wyoming.

Anyone traveling or returning to New Jersey from these states is being urged to quarantine for 14 days once they arrive to prevent the spread of the coronavirus.

Murphy says that Connecticut, Delaware and Pennsylvania now technically meet the criteria to also be on the list, but because of the interconnected nature of the region and mode of transportation between New Jersey and the states, Murphy said that a 14-day quarantine is not reasonable. But the governor does say that traveling to these states is highly encouraged.

“Cases have continued to increase at alarming rates, in our state and across the country and it is imperative that we keep the spread of COVID-19 under control,” Murphy said in a statement.
