Spain has agreed to welcome a cruise ship carrying passengers with confirmed and suspected cases of hantavirus, according to the World Health Organization.

The decision allows for the urgent medical evacuation of sick passengers and the tracing of contacts to prevent a wider outbreak. While hantavirus is typically transmitted through rodent droppings, health officials are monitoring the vessel for rare human-to-human transmission.

The ship is currently anchored off Cape Verde. Maria Van Kerkhove, a director at the WHO, said the plan now is for the ship to continue on to the Canary Islands [1].

Authorities have confirmed two cases of hantavirus aboard the ship [4], while another five cases are suspected [4]. The outbreak has already resulted in three deaths among passengers [5].

A WHO spokesperson said there may be some ongoing human-to-human transmission aboard the ship as it prepares to medically evacuate two passengers [2]. This possibility has led to increased surveillance by international health bodies.

Despite the cases on board, the risk to the general public remains low. The European Centre for Disease Prevention and Control said the public health risk to Europeans from the hantavirus outbreak detected on a cruise ship in the Atlantic remains very low [3].

Spanish authorities are coordinating with the WHO to ensure that the arrival of the ship does not compromise regional health security. The coordination includes strict protocols for the transfer of patients to medical facilities in the Canary Islands.

“The public health risk to Europeans from the hantavirus outbreak detected on a cruise ship in the Atlantic remains very low.”

The agreement by Spain to accept the vessel highlights the tension between maritime quarantine protocols and the humanitarian necessity of medical evacuation. Because hantavirus is not typically a contagious respiratory illness, the WHO's focus on potential human-to-human transmission suggests a cautious approach to a rare clinical presentation, ensuring that the evacuation does not trigger a terrestrial cluster.
