The World Health Organization suspects limited human-to-human transmission of hantavirus aboard the MV Hondius cruise ship following a deadly outbreak [3, 5].

This development is significant because hantaviruses are typically transmitted to humans through rodent droppings or urine, rather than between people. Evidence of person-to-person spread could change the public health approach to containing the virus.

The cruise ship is currently stranded in the Atlantic Ocean [1]. The vessel had recently called at several islands off the coast of Africa before the outbreak occurred [1, 2].

Three people have died on board the ship [2]. Additionally, two ill crew members are currently awaiting evacuation [1]. There are approximately 150 passengers aboard the vessel [1].

WHO officials said that the outbreak began when rodent-borne hantavirus infected crew members [2, 5]. While the organization is now investigating the possibility of limited spread between humans, it emphasized that the broader threat is contained.

"The risk to the public remains low, but we are monitoring the situation closely," a World Health Organization spokesperson said [5].

The investigation continues as health officials work to stabilize the remaining crew and passengers. The ship remains isolated in the Atlantic to prevent further potential exposure while the WHO monitors the clinical progression of those infected [1, 5].

“Three people have died on board the ship.”

If the WHO confirms human-to-human transmission, it represents a rare and concerning shift in the behavior of hantaviruses, which are generally zoonotic. While the current risk to the global public is rated as low, this incident may prompt stricter health screenings and rodent control protocols for cruise ships operating near coastal Africa and the Atlantic.
