The Ruby-Princess has been grappling with a series of significant health outbreaks impacting both crew and passengers. In a disconcerting trend, the vessel reported a second outbreak of acute gastroenteritis, specifically attributable to norovirus, during its latest cruise that began in early July. On July 5, just prior to its arrival in Haines, Alaska, the ship had recorded six crew members and one passenger in isolation due to gastrointestinal issues such as diarrhea and vomiting—a recurrent issue that has come to plague the vessel's recent sailings.
This outbreak follows another alarming incident earlier in the same month, where the Centers for Disease Control and Prevention (CDC) confirmed that 145 people—125 passengers and 20 crew members—were affected during a prior 20-day journey from San Francisco to Alaska. Such numbers represent a concerning trend as this marks the cruise line's third significant outbreak within the year, with similar health threats reported on the ship earlier in June.
The immediate response from the cruise line has included strict isolation protocols for the affected individuals, as well as enhanced cleaning and disinfection measures throughout the ship. Post-outbreak, disinfection procedures have been intensified to mitigate further spread, involving complete disinfection of common areas and isolating sick guests to curb additional infections. Nevertheless, the Ruby-Princess is scheduled for further voyages to locations like Tracy Arm, Ketchikan, and Prince Rupert, British Columbia, creating a delicate balance between maintaining operational schedules and ensuring passenger health and safety.
This recent string of illness outbreaks has certainly raised concerns about the operational protocols for health management on cruise ships, especially as travel demand increases in the post-pandemic environment. Despite the challenges, the cruise line is preparing for the resumption of cruises, indicating that they are committed to improving their health safety protocols in collaboration with health authorities as they proceed into new itineraries.
