Post-hantavirus outbreak, infectious disease experts share how to cruise safely—and assess the health risks
A hantavirus outbreak on the MV Hondius cruise ship has brought some health and safety questions about cruises back into the public eye. Here's what doctors say.
TL;DR
- Cruises do not pose a significant public health risk, and the hantavirus strain involved in a recent outbreak has a low transmission rate.
- Passengers are more likely to contract common illnesses like the flu, cold, RSV, Covid, or norovirus on a cruise than hantavirus.
- Cruise ships are enclosed spaces with high population density, which can facilitate the spread of infectious diseases.
- The cruise industry reports illnesses more frequently than land-based settings, but trade organizations state that overall illness rates are low and often lower than on land, with strict health protocols in place.
- The cruise industry experienced a record high in passenger volume in 2025, indicating a strong post-Covid recovery.
- Experts recommend practicing excellent hand hygiene, getting necessary vaccinations before boarding, and maintaining social distance when needed, particularly if feeling sick or observing symptoms in others.
- Washing hands for at least 20 seconds or using hand sanitizer is crucial, and disinfecting surfaces in cabins can add an extra layer of precaution.
- Consulting a doctor about relevant immunizations for destination ports is advised, especially for individuals with compromised immune systems.
- If feeling unwell, passengers should visit the ship's health clinic and proactively maintain social distance, potentially wearing a mask.
