The cruise ship Norwegian Breakaway, owned by Norwegian Cruise Line Holdings Ltd, departed New Orleans on a weeklong cruise on Nov. 28 and had stops in Belize, Honduras and Mexico, the health agency said. "NCL has been adhering to appropriate quarantine and isolation protocols," the department said in a tweet. The ship is set to reach New Orleans on Sunday morning, according to its itinerary. Everyone on board will be tested for COVID-19 before leaving and will be provided with post-exposure and quarantine public health guidance by the U.S. Centers for Disease Control and Prevention (CDC). People who test positive for COVID-19 will either travel to their homes or self-isolate according to CDC guidelines, the health agency said.
