Based on the below, this would mean 1.4 people tested positive assuming about 1,400 guests. I'd really like to know the actual circumstances but that doesn't sound crazy.
Yellow Ship Criteria
- Ship is at or above CDC’s investigation threshold:
- Restricted Voyages:
- 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 largest cruise ships can carry up to 6500 passengers on board.
