A rare and unsettling health crisis has unfolded across the South Atlantic, triggering a coordinated multinational alert. What initially appeared to be isolated cases of respiratory distress among passengers has escalated into a confirmed Andes hantavirus outbreak, leaving three dead and health authorities racing to map the infection's trajectory.
Health authorities across several nations are examining exposure routes, passenger movements, and possible points of infection as the cruise ship arrives in Spain's Canary Islands.
Unlike typical hantaviruses, which are usually contracted via rodent-to-human contact, the Andes strain (ANDV) is uniquely dangerous due to its capacity for human-to-human transmission.
Though overall global risk is low, the spread of alerts across countries shows how quickly such events can cross borders in modern travel.
As per the WHO, at least 12 countries have now been officially or indirectly connected to the outbreak response. Canada, Denmark, Germany, The Netherlands, New Zealand, Saint Kitts and Nevis, Singapore, Sweden, Switzerland, Türkiye, The United Kingdom and the United States of America are among the countries notified.
In some places, passengers were evaluated after disembarkation. In others, authorities are simply tracking citizens who were on board during the voyage.
Some passengers developed fever, fatigue, and gastrointestinal symptoms.
What are the things global travellers should keep in mind?
*Hantavirus is not typically spread from person to person. It is a zoonotic disease spread by rodents, including rats.
*The virus is shed in rodent urine, droppings, and saliva. When these dry out and are stirred up (like when sweeping a dusty shed), the viral particles become airborne. Travellers inhale these "aerosols."
*Touching contaminated surfaces and then touching your nose or mouth.
*Travellers are most at risk when they enter environments where rodents have nested undisturbed.
*Closed, dusty spaces are prime locations for viral particles and walking through heavy brush where rodents live is a high-risk zone.
*Since the incubation period is usually 1 to 8 weeks, initial symptoms should not be missed. Fever, severe muscle aches (especially in the thighs and back), headaches, and abdominal pain are some of the symptoms.
*If you develop a sudden shortness of breath or a dry cough after being in a rural area, seek medical attention immediately.
Prevention tips
* If staying in a cabin, open all doors and windows for at least 30 minutes before entering.
*Never sweep or vacuum dry rodent droppings. Spray the area with a 10% bleach solution or disinfectant until soaked, then wipe it up with paper towels while wearing a mask and gloves.
*Use rodent-proof containers for all snacks and supplies while camping.
*Avoid camping near woodpiles, garbage dumps, or areas with visible rodent activity.
