The CDC is investigating or observing 86 cruise ships after COVID-19 outbreaks, including all four Disney Cruise Line ships.

The Disney Fantasy has been investigated and is under observation. The CDC is starting investigations on the Disney Dream, Magic, and Wonder.

All the Disney ships have a yellow status, which is the threshold for a CDC investigation. None of the ships being investigated are at the highest status of red.

Here is the yellow criteria according to the CDC:

• Cases reported in 0.10% or more of passengers (e.g., if 6500* passengers on board, CDC’s investigation threshold is met if there are 7 or more cases among passengers occurring during the previous 7 days), or
• This percentage includes passenger cases occurring within 5 days of disembarkation that CDC was notified of by state or local health departments.
• One or more cases reported in crew.
• Simulated Voyages:
• Cases reported in 1.5% or more of passengers, or
• Cases reported in 1.0% or more of crew.
• Ships with Crew Only (i.e., not yet submitted requests for simulated voyages or applications for restricted voyages, pending CDC approval, or sailing at a later date).
• Cases reported in 1.0% or more of crew.
• OR
• During the past 7 days, the ship failed to submit one or more daily EDC submissions on time (by 1200 ET). On a weekly basis, CDC emails all ships a reminder to submit the EDC form. In addition, CDC sends a reminder email if a ship does not submit their EDC form.

The Disney Dream and Disney Fantasy hold a maximum of 4,000 passengers but are currently operating at about half-capacity.
