The U.S. government is preparing to evacuate American citizens aboard the Diamond Princess cruise ship, the site of the most coronavirus infections found outside China and currently quarantined off Japan, the Wall Street Journal reported.

About 380 people will be offered seats on two planes back to the United States and could arrive back home as early as Sunday, the newspaper said, adding that those with a fever, cough or other symptoms will not be allowed on the flights.

Evacuees will have additional health screenings in the United States and some will probably undergo a mandatory quarantine, which will likely be 14 days, Henry Walke, an official at the Centers for Disease Control and Prevention (CDC), was quoted as saying.
