Coronavirus (COVID-19) … What did the Cruise Lines Know? A Maritime Lawyer’s Analysis

Part 1: Chronology / Timeline of Pandemic Aboard Cruise Ships

Of late, cruise ships have been referred to as “floating petri dishes” following numerous shipboard outbreaks of Coronavirus/ COVID-19. This article will examine: to what extent the cruise industry contributed to the spread of the COVID-19 pandemic, what the cruise industry knew and when, and if certain cruise lines can be held liable to cruise passengers and crewmembers for serious illness and in certain instances death from contracting COVID-19 while traveling on a cruise ship.

First Shocking Fact: During February–March 2020, COVID-19 outbreaks associated with three cruise ship voyages accounted for more than 800 laboratory-confirmed cases among passengers and crew according to the US Centers for disease Control and Prevention’s (“CDC’s”) March 23, 2020 article. Transmission occurred across multiple voyages from ship to ship by crew members, both crew and cruise passengers were affected and at least 10 deaths resulted involving crew and passengers who contracted COVID-19 while sailing or working aboard these cruise ships. A more recent article in Bloomberg News provides that after the outbreak on the Diamond Princess, “[a]t least seven more of [Carnival’s cruise ships or brand name lines] at sea have become virus hot spots, resulting in more than 1,500 positive infections and at least 39 fatalities.”

Below is a timeline of the more salient events leading up to these tragic events and present dire circumstances:

“Last Updated”

The U.S. Department of State – Bureau of Consular Affairs issues a travel advisory, providing: “Passengers on Cruise Ships … U.S. citizens, particularly travelers with underlying health conditions, should not travel by cruise ship. CDC notes an increased risk of infection of COVID-19 in a cruise ship environment. In order to curb the spread of COVID-19, many countries have implemented strict screening procedures that have denied port entry rights to ships and prevented passengers from disembarking. In some cases, local authorities have permitted disembarkation but subjected passengers to local quarantine procedures. While the U.S. government has evacuated some cruise ship passengers in recent weeks, repatriation flights should not be relied upon as an option for U.S. citizens under the potential risk of quarantine by local authorities.

This is a fluid situation. CDC notes that older adults and travelers with underlying health issues should avoid situations that put them at increased risk for more severe disease. This entails avoiding crowded places, avoiding non-essential travel such as long plane trips, and especially avoiding embarking on cruise ships. Passengers with plans to travel by cruise ship should contact their cruise line companies directly for further information and continue to monitor the website …”.
