CDC Cruise Ship color status - knowledge bomb

[bgoff60]

With all the conjecture, hyperbole and rhetoric out there that seems to usually go off the rails on what statistic or metric to use...

thought I would quote from the preverbal houses mouth.  

Go here to see how the CDC is "grading' each cruise ship that is sailing.  https://www.cdc.gov/quarantine/cruise/cruise-ship-color-status.html

You can scroll down to see your ship but at the top of their grid, there are links to what EACH color category means and does not mean.  

Moderator:  You may want to pin this...

 

here is the TL;DR version...

 

Definition of a COVID-19 Case for the Purpose of Ship’s Color Status

• A positive viral test result for COVID-19 in any traveler (passenger or crew member)
• COVID-19-like illness in any traveler (passenger or crew member) with:
  • a negative or repeatedly inconclusive/invalid test result (i.e., never able to register a positive or negative result) for COVID-19 and with no other laboratory-confirmed respiratory pathogens (e.g., influenza, respiratory syncytial virus, Legionella, Streptococcal pharyngitis), or
  • an unavailable test result (e.g., traveler refuses to be tested, testing resources unavailable onboard).
• The following persons are not included when determining a ship’s color status:
  • passengers who test positive on day of embarkation who do not board the ship, or
  • newly embarking crew members who test positive during quarantine.

Green Ship Criteria

• No reports of COVID-19 or COVID-19-like illness (CLI) for 7 days, as determined by a qualified medical professional, and
• On-time (by 1200 ET) daily submission of EDC form during past 7 days.

Orange Ship Criteria

• COVID-19 or CLI has been reported in the past 7 days, and the ship is below CDC’s investigation threshold:
  • Restricted Voyages:
    • Cases reported in less than 0.10% of passengers (e.g., if 6500* passengers are on board, it would take at least 7 passenger-cases during the previous 7 days to meet CDC’s investigation threshold), and
    • No crew cases reported.
  • Simulated Voyages:
    • Cases reported in less than 1.5% of passengers, and
    • Cases reported in less than 1.0% 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 less than 1.0% of crew.

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.

Red Ship Criteria

• For a ship to be considered at Red status, the ship has:
  • sustained transmission of COVID-19 or CLI, or
  • potential for COVID-19 cases to overwhelm on board medical center resources.
• In addition, CDC will work closely with the cruise line and consider multiple factors before assigning a “Red” status to the ship. These factors may include, but are not limited to the following:
  • Percent of passengers and crew on board who are fully vaccinated.
  • Variants of concern are identified among cases on board.
  • Epidemiologic data from EDC reporting (e.g., symptomatic persons on board requiring medical care)
  • Epidemiologic links between cases.
  • Number of hospital beds, ventilators, oxygen, and other medical supplies on board relative to the number of cases on board.
  • Ship has not replied to CDC’s request for information within 48 hours.
  • During the past 7 days, the ship missed one or more daily submissions of the EDC form. 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 colors are meaningless, despite those definitions.

Merely a tool to help some make informed decisions.  If the boat I am contemplating is at a RED status, I might thing differently vs. green or orange.

YMMV.  Just offering up another place to get information.

Thanks

Well red is one thing. But yellow/orange are based on past data (obviously) but a case of covid one week plays no bearing on the odds for covid the next week
