According to reports by The New York Times, passengers crossing the Atlantic have resumed COVID-era precautions, including repeated hand sanitising, social distancing and modified meal arrangements, while health officials monitor the situation closely.
The vessel is expected to dock in Tenerife after the Spanish government approved plans for medically fit passengers to disembark and return home.
Spain’s Health Minister, Mónica García, confirmed the decision despite growing concerns from regional authorities in the Canary Islands.
Fernando Clavijo, head of the Canary Islands government, criticised the arrangement, questioning why the ship was required to sail for several more days before docking.
Health fears intensified after three passengers died and several others reportedly developed symptoms linked to the virus.
The World Health Organization confirmed that the cases involve hantavirus, a rare but potentially severe infection commonly transmitted through rodents.
Despite the fatalities, WHO Director-General Tedros Ghebreyesus said the overall public health risk currently remains low.
Medical evacuations have already been carried out, with three passengers, including two with acute symptoms, transported to the Netherlands for specialised treatment.
Authorities said the outbreak involves the Andes strain of hantavirus, one of the few variants known to spread between humans through close and sustained contact.
The hantavirus cruise ship outbreak has also triggered contact tracing efforts in South Africa, where health officials are monitoring dozens of people believed to have been exposed.
South African Health Minister Aaron Motsoaledi said authorities had identified 62 contacts, with 42 already traced and placed under observation.
On board the ship, passengers have been instructed to wear masks, maintain distancing and comply with enhanced hygiene protocols.
Sanitiser stations have been installed across the vessel, while dining arrangements have been redesigned to reduce close contact.
One passenger told The Times that morale on board remained stable despite uncertainty surrounding the outbreak.
Investigators are also examining whether the infection may have originated during earlier travel in Argentina or elsewhere in South America before passengers boarded the ship.
According to a health advisory from Harvard University, hantavirus was first identified near Korea’s Hantaan River region and is usually spread through exposure to infected rodent saliva, urine or droppings.
The advisory notes that although infections are rare, the disease can become severe when it affects the lungs, kidneys or heart.
Experts further explained that human-to-human transmission remains unusual, but the confined environment aboard a cruise ship may have contributed to the limited spread now under investigation.
Symptoms typically begin with fatigue, fever and muscle pain before progressing to headaches, dizziness and stomach complications.

In serious cases, patients may suffer respiratory distress, coughing and breathing difficulties as fluid builds up in the lungs.
