Cruise organization suggests some people 70+ should be barred from boarding ships

11:50 a.m.:

A proposal submitted to the White House Tuesday by the leading cruise trade organization would deny cruise boarding to any person over 70 unless they are able to present a doctor's note verifying their fitness for travel.

Cruise Lines International Association (CLIA) submitted a plan to Vice President Michael Pence proposing enhanced measures across the industry as coronavirus rages on, forcing two ships of passengers into quarantine and escalating fears on others.

Similarly, any person with a chronic medical condition who could be at an increased risk if they were to contract COVID-19 should be barred from getting on a cruise ship.

At a briefing Tuesday night, Pence confirmed he had received CLIA's proposal. "We'll be reviewing that in the next 24 hours," he added.

"The President's objective is for us to make cruise lines safer, even as we work with the cruise lines to ensure that -- that no one in our particularly vulnerable population is -- is going out on a cruise in the near future."

11:26 a.m.

After jumping by eight confirmed cases overnight, 12 hours later, the number of confirmed cases of coronavirus in Florida stayed at 21 Florida, according to the latest update from the Florida Department of Health.

More than a dozen cruise ships on their way to Florida ports

10:45 a.m.

At least 30 cruise ships currently at sea list port destinations in the United States sometime this week, according to a USA TODAY satellite tracking analysis of 380 of the world’s largest cruise ships.

Since this is prime Caribbean cruising season, more than a dozen of those 30 ships are bound for the Florida cities of Key West, Cape Canaveral, Fort Lauderdale and Miami.

The world’s largest cruise ship, Royal Caribbean’s Symphony of the Seas, left Miami last weekend for a Caribbean cruise and is scheduled to head back there Saturday with a staggering capacity of 5,000 passengers and 2,300 crew.

At present, none of the ships currently at sea have reported passengers with symptoms of the coronavirus, or COVID-19. Such a report could, as was the case with the Grand Princess, trigger changed itineraries, port delays, helicopter evacuations and long quarantines.

FSU students may have been exposed to coronavirus at national conservative conference

9:16 a.m.:

A group of Florida State University students who returned to campus from the 2020 Conservative Political Action Conference (CPAC) in Washington, D.C. — where an attendee turned up positive for the coronavirus — were told to follow federal guidelines for self-isolation.

“We have communicated with the students we know attended this conference,” FSU spokesman Dennis Schnittker said. “However, since it was not a university event, we may not have a complete list of who was there.”

About a dozen students from the FSU College Republicans attended the conference, held Feb. 26-29, according to the organization's Facebook page.

Coronavirus not affecting Florida presidential primary yet

2:40 p.m. Tuesday

Election officials in Florida are monitoring the ever-intensifying coronavirus outbreak, and so far, next Tuesday’s presidential preference primary remains largely unaffected.

Florida’s elections laws, however, give broad emergency authority to modify or postpone elections in the event of an outbreak, a power granted after Hurricane Andrew hit the state in 1992.

That means the governor and the Department of State, which oversees elections, could expand vote-by-mail, move precinct locations or allow for new voting methods.

In extreme cases, the Florida Administrative Code allows county supervisors to email absentee ballots on election day and allow voters to fax in their ballots.
