All of the nearly 500 Grand Princess cruise ship passengers who were quarantined at Dobbins Air Reserve Base in Marietta have left the military installation, the U.S. Health and Human Services Department announced Thursday.

Most have returned home. At one point, 15 were relocated to a former Radisson Hotel the federal government is leasing in Marietta. Seven remained there Thursday morning. The hotel, according to HHS, is reserved for passengers who need to be isolated but not hospitalized.

“HHS is pleased to report that all Grand Princess passengers have departed Dobbins Air Reserve Base and Clay National Guard Center,” HHS said.

As of Monday, there were 197 Grand Princess cruise ship passengers from 23 states at Dobbins. Earlier this month, Vice President Mike Pence said 21 people aboard the cruise ship tested positive for the COVID-19 infection, including 19 crewmembers and two passengers.
