Hantavirus Outbreak on the MV Hondius
Between April and May 2026, the MV Hondius cruise ship experienced an outbreak of hantavirus (Andes virus), leading to 13 infections and three fatalities. The vessel carried 175 people from over 20 countries and was sailing across the Atlantic Ocean. The first death occurred ten days after departing a port in Argentina, claiming a Dutch national. Subsequently, his wife and a German female passenger also succumbed to the infection.
The last passenger exposed to infected individuals completed quarantine, tested negative, and returned home. No new infections have been reported since May 25. In late April, 34 passengers left the ship, with some later testing positive for hantavirus. Others were evacuated to Tenerife and then repatriated to their home countries for quarantine. The MV Hondius arrived in Rotterdam, Netherlands, for decontamination on May 18, 2026.
Stomach Virus Outbreak on the Ruby Princess
In early July 2026, a highly contagious stomach virus swept through the Ruby Princess cruise ship during a 20-day voyage from San Francisco to Canada and Alaska. According to the CDC, 102 passengers and 23 crew members contracted the infection. The Ruby Princess carried a total of 3,032 travelers and 1,144 staff.

Cruise operators and health authorities must implement robust measures to prevent such incidents from recurring in the future.
This report highlights two separate health emergencies aboard cruise vessels in 2026, underscoring ongoing concerns about disease control in confined travel environments.
The recent hantavirus outbreak on the MV Hondius is not an isolated incident in the cruise industry. Just months later, the Ruby Princess faced its own crisis as a norovirus outbreak affected dozens of passengers during a voyage. These events highlight the persistent challenges of managing health risks in crowded travel environments, emphasizing the need for improved preventive measures by cruise operators.
