All passengers age 12 and older were required to be fully vaccinated and to test negative to board the Symphony of the Seas ship.
Forty-eight people on board Royal Caribbean’s Symphony of the Seas ship that ended a seven-day sailingin Miami on Saturday tested positive for COVID-19 during the cruise, the cruise line said in an updated statement shared Monday morning.
Those 48 people who tested positive represented 0.78% of the 6,091 passengers and crew members on board Symphony of the Seas, which left Miami on Dec. 11 and made stops in St. Maarten, St. Thomas, and Perfect Day at CocoCay (Royal Caribbean’s private island), the cruise line said in an updated statement provided Monday morning by spokesperson Lyan Sierra-Caro.
Initially, the cruise line reported 44 cases on board. “This number (48) includes four additional close contacts which were identified as COVID-19 positive at the end of the voyage,” Sierra-Caro said Monday. “The guests were quarantined on board and assisted upon the ship’s arrival on Dec. 18.”
All passengers 12 and older were required to be fully vaccinated and to test negative to board the Symphony of the Seas ship. The ship sailed with 95% of the onboard community fully vaccinated on the Dec. 11 to Dec. 18 cruise, with 98% of those people who tested positive being fully vaccinated, Royal Caribbean said.
On Saturday, the cruise line also notified passengers from that trip and from two others (a sailing that departed Dec. 4 and one that departed Dec. 18) that a passenger who sailed on that same ship earlier this month tested positive for the omicron variant of the coronavirus.
“We were notified by the (Centers for Disease Control and Prevention) that a guest on board our (December) 4th cruise tested positive and it was identified as omicron,” Sierra-Caro said Saturday. “They asked us to notify guests on the sailing – the one that ended today – and the current one.”
In the email to the passengers who sailed on the three cruises on Symphony of the Seas, Royal Caribbean outlined what happened.
“This guest did not report symptoms to our onboard medical teams as outlined in our health protocols,” the cruise line said in a copy of the email obtained by USA TODAY. “Their post cruise test results were subsequently confirmed as the omicron variant.”
The 48 cases on the recently disembarked cruise “were found as a result of immediately identifying close contacts after a guest tested positive,” Sierra-Caro said, noting each person was quarantined quickly.
Initially, Royal Caribbean said that everyone who tested positive was asymptomatic. In the statement Monday morning, it said that “everyone who tested positive were asymptomatic or had mild symptoms, and we continuously monitored their health.”
Six passengers disembarked earlier in the cruise and were transported home. The rest of the passengers were assisted Saturday at disembarkation in Miami, Sierra-Caro said.
In the email to passengers, Royal Caribbean said that the cases on the Dec. 11th sailing were “unrelated to the omicron case from the guest who sailed on Dec. 4th.”
It is not immediately clear why the cases were unrelated.
The cruise line advised that passengers visit a certified testing center three to five days after disembarkation, per CDC guidance.
On Saturday, the CDC said in a statement that the agency was aware of the situation on Symphony of the Seas and that it was working with the cruise line to gather more information.
On Monday, the CDC told USA TODAY in a statement provided by spokesperson David Daigle that the health agency continues to work with Royal Caribbean to gather information about the cases and potential exposures. The CDC added that “RCI collected specimens from the voyage that sailed from 12/11-12/18 for genetic sequencing.”
On the CDC’s cruise ship color status list, Symphony of the Seas is “Yellow,” indicating that the “CDC has investigated and the ship remains under observation,” according to the agency.
