Cruise Ship Outbreaks: Rare but Ships Are Well Prepared

What Happened on the Hondius?

A recent viral outbreak aboard the Dutch cruise ship Hondius has raised questions about safety at sea. While the situation was serious, experts say such outbreaks are extremely rare. In 2025, over 37 million people worldwide took a cruise, according to industry data. The last major deadly outbreak on a cruise ship was at the start of the COVID-19 pandemic over six years ago. Cruise lines are now well prepared, with medical centers and trained staff ready to respond.

How Cruise Ships Prepare for Medical Emergencies

Cruise ships are required by international regulations to have fully equipped medical facilities. According to cruise expert Nico van Dijk of DeCruiseGids.nl, every ship has a medical center with doctors and nurses. The size of the medical team depends on the number of passengers. The new German ship Mein Schiff Relax, carrying nearly 4,000 passengers and 1,100 crew, has multiple doctors and several nurses on board.

Onboard Hospital and Mortuary

Van Dijk toured the medical facilities of the Mein Schiff Relax last year. He saw a modern hospital with an intensive care area, an isolation room, and a mortuary. The mortuary can hold up to five bodies in cooled aluminum drawers, similar to those seen in American TV series. 'It is not the case that a body disappears into the sea,' Van Dijk explained. The 2025 cruise industry safety standards require these facilities for hygienic and respectful storage until the body can be brought ashore.

Medical Response Protocols

When a virus outbreak occurs, the ship's doctor decides whether a patient needs to be evacuated. The captain determines how this is done, says Ramsey Albers of the Royal Association of Netherlands Shipowners (KVNR). If the ship is near land, evacuation by boat or helicopter is possible. On the open ocean, the medical team follows guidelines from the RIVM and the World Health Organization. In extreme cases, the captain may speed up to the next port or change course.

Safety Drills and Hygiene Measures

Since the Costa Concordia disaster in 2012, safety protocols have been tightened. Every passenger must attend a safety drill on the first day before the ship can depart. During the drill, crew explain where lifeboats are and what to do when the alarm sounds. While virus outbreaks are not specifically covered, strict hygiene measures are enforced. Hand sanitizer dispensers are everywhere, and passengers are encouraged to disinfect their hands regularly.

How Common Are Outbreaks?

According to Van Dijk, considering the millions of passengers each year, virus outbreaks are rare. The last major outbreak with fatalities was during the early COVID-19 pandemic. The hantavirus outbreak on cruise ships is extremely unusual. Experts emphasize that the industry has learned from past incidents and continuously improves its medical preparedness.
