US cruise lines have suspended all cruise ship services in the US and have been told to suspend all ship and cruise tours in the area.
The cruise line Carnival said on Tuesday that all of its ships would be closed in the state of Florida, including the Carnival Triumph and Carnival Cruises.
The US Coast Guard has confirmed more than 7,300 cases of the coronaviruses coronaviral disease and salmonella, including a number of deaths.
All the ships were en route to or from the Bahamas.
The Carnival Triumph was grounded for 24 hours last week after the Coast Guard detected more than 2,000 cases of salmonellosis.
The coast guard has said that more than 50 cruise ships have been in the Florida area since October.
The company said it had shut down the cruise lines and tours, but it said that the shutdown would not affect other guests or crew members.
Carnival said the affected ships would not be permitted to leave the US or re-enter the United States until all affected passengers have been properly tested and their records are cleared.
The Florida Department of Environmental Protection said on Monday that it had ordered the removal of about 300 tons of sand from a beach in the city of Boca Raton that had been washed out during the recent coronavivirus outbreak.
