(CNN) — At least 13 crew members who were displaying respiratory symptoms consistent with pneumonia and bronchitis have been evacuated from two cruise ships near Florida, according to Miami-Dade County government.
Six crew members from the Costa Magica and seven from the Costa Favolosa were transported to a hospital once on shore by Miami-Dade Fire, according to a tweet from Miami-Dade County Emergency Management.
According to Miami-Dade officials, the US Coast Guard helped evacuate the patients and has ordered both vessels to remain 3 miles near shore.
Earlier Roger Frizzell, a spokesman for parent company Carnival cruises said about 30 crew members on board the two ships had influenza-like symptoms.
Costa’s Favolosa and Magica do not have official clearance to enter the Port of Miami at this point, Frizzell said.
In total, more than 1,000 crew members are on board the ships, but no passengers.
CNN has reached out to the Port of Miami and other stakeholders and has not heard back.
Meanwhile, at least 77 people — 30 guests and 47 crew members — aboard Holland America’s Zaandam ship have reported experiencing flu-like symptoms, the cruise line said in a statement.
All 1,243 guests have been asked to stay in their rooms as the ship sails to Fort Lauderdale, where it is expected to dock Monday.
“Since it is flu season, and (Covid-19) testing is not available on board, it is difficult to determine the cause of these elevated cases at this time,” the release says.
All ports along the Zaandam’s route are closed to cruise ships. Holland America deployed a second ship — the Rotterdam — with extra supplies, staff, Covid-19 test kits and other support as needed to meet the Zaandam on Thursday night.
“The safety and well-being of our guests and crew is one of our highest priorities,” the statement said.
There are 586 crew members on board. Those not required to operate the ship are in quarantine while those who are needed to maintain operations are self-isolating when not working.
Those who are experiencing symptoms have been isolated and their close contacts are in quarantine, according to the statement.
