As of Saturday, regardless of the omicron surge, cruise lines will not be obliged to follow COVID-19 safety guidelines issued by the Centers for Disease Control and Prevention. The CDC’s Conditional Sailing Order, a set of health and safety rules that cruise companies have had to abide by since October 2020, expired on Saturday. The agency will “transition to a voluntary program, in coordination with the cruise ship operators and other stakeholders, to assist the cruise industry to detect, mitigate, and control the spread of COVID-19 onboard cruise ships.” “The transition of the Conditional Sailing Order (CSO) to a voluntary program … recognizes the cruise industry’s unwavering commitment to providing some of the highest levels of COVID-19 mitigation found in any industry,” a statement from industry group Cruise Lines International Association notes.

Masks are also mandatory indoors at all times, excluding eating and drinking. The CSO also required that ships conduct simulated voyages in order to test their COVID-19 mitigation efforts. While the safety guidelines will now be voluntary, many cruise lines are expected to keep at least some or all of them in place. “Given this oversight and the uniquely high vaccination rate required on board, the incidence of serious illness is dramatically lower than on land, and hospitalizations have been extraordinarily rare even while landside hospitalizations are peaking,” CLIA stated. Cruise ships that opt in to the program will be required to report new outbreaks to the CDC, which classifies the severity of each ship’s outbreak by color. Companies that do not participate will be listed by the CDC in gray, indicating that the “CDC has not reviewed or confirmed the cruise ship’s health and safety protocols.” [tweet_embed] January 17, 2022[/tweet_embed] The CSO expiration date comes just two weeks after the CDC heightened its risk level of cruising to four, the highest classification. The agency pressed that even people who have been vaccinated should reconsider travel plans, and anyone going on a cruise should test for COVID-19 before and after travel. The rate of new infections recorded at sea is climbing, according to CDC Director Rochelle Walensky. Last month, the agency reported that ships operating in U.S. waters confirmed more than 5,000 COVID-19 infections between Dec. 15 and Dec. 29, up from just 162 cases during the first two weeks of the month.
