A recent norovirus outbreak on the Holland America Line’s cruise ship, the Westerdam, has raised concerns following its journey from Yokohama, Japan, to Hong Kong. According to the Health Protection Centre (CHP) of Hong Kong, a total of 76 individuals were reported to have fallen ill during the 14-night voyage, which included 65 passengers and 11 crew members.

Health officials first became aware of the situation on February 27, while the ship was still at sea. Passengers and crew began exhibiting symptoms associated with acute gastroenteritis, such as vomiting, diarrhoea, and fever, shortly after the Westerdam departed Yokohama on February 15.
Upon arrival at the Kai Tak Cruise Terminal on March 1, immediate investigations were launched by the CHP. Experts from various divisions were dispatched to conduct environmental assessments and epidemiological investigations on board the vessel. They inspected food hygiene practices and provided a temporary medical station where health assessments could be conducted for those on board.
In a statement, Holland America acknowledged the reports of gastrointestinal illness. The cruise line noted that the symptoms among those affected were mostly mild and resolved quickly. However, the company took extra precautions by implementing enhanced sanitation measures and deep cleaning procedures before the ship was allowed to depart from Hong Kong for its next journey.
Approximately 2,000 passengers and 800 crew members were aboard the Westerdam during its voyage. The ship made multiple stops in Japan before continuing to Busan, South Korea, and ultimately heading to Hong Kong. Following the outbreak, all boarding procedures for the next voyage were put on hold until a thorough cleaning and disinfection was completed, with hygiene conditions found to be satisfactory.
Dr. Edwin Tsui, Controller of the Centre for Health Protection, expressed concern over the rising incidence of norovirus in the region. With increased activity in tourist hotspots, particularly in Japan and Korea, he urged both passengers and cruise operators to exercise heightened diligence with respect to personal and environmental hygiene. Ensuring extensive cleaning protocols can help safeguard public health and individual well-being on these maritime voyages.
The CHP has committed to actively following the outbreak and continuing its collaboration with relevant departments to monitor the situation. As a precaution, additional health assessments may be introduced for future cruise arrivals, especially given the current climate of heightened norovirus activity.
Following the incident, the Westerdam has already set sail again for its next itinerary, which includes stops in the Philippines, China, and Japan, before returning to Yokohama. The quick response from health authorities serves as a reminder of the importance of maintaining rigorous health and safety measures within the travel and tourism sectors, especially in light of recent viral outbreaks.
As cruise tourism continues to bounce back globally, both passengers and operators must remain vigilant to ensure the safe enjoyment of maritime adventures. The spectacle of cruising should not overshadow the vital importance of health protocols, which are essential to prevent similar incidents in the future. Further updates from the CHP are anticipated as they continue to monitor and investigate the outcomes of this latest outbreak.
