The management of an international health crisis has positioned Tenerife, a Biosphere Certified destination, as a benchmark in global cooperation, health response, and the application of sustainability to tourism. This case demonstrates that sustainability is not only about protecting the environment, but also about anticipating risks, coordinating effective responses, and safeguarding the health of residents and visitors in an interconnected world.

Tenerife and the sustainable management of an international crisis.

In a world where borders seem to blur in the face of major global challenges, the management of health crises has become the ultimate measure of a destination’s maturity. What began as a scientific expedition in the remote waters of Patagonia and Antarctica has ended up placing the island of Tenerife at the center of an unprecedented international cooperation operation: the management of the Andes strain hantavirus outbreak aboard the MV Hondius.

As a Biosphere Certified Destination, Tenerife not only works to preserve its landscapes or reduce its carbon footprint. It works, together with other organizations and institutions at national and international levels, to demonstrate that sustainability is, above all, a matter of human responsibility, health security, and international collaboration.

A health crisis of global dimension.

The hantavirus crisis on the MV Hondius has not been merely a medical incident aboard a vessel. It has represented a highly complex transcontinental challenge, requiring the location of 30 passengers who had already returned to their homes in 12 different countries after disembarking on the island of Saint Helena, as well as the tracing of their close contacts. At the same time, it required maintaining individualized daily monitoring of the 147 crew members and passengers of 23 different nationalities who remained under health control, in addition to coordinating their subsequent return to their countries of origin.

All of this has required, within a relatively short period of time, the articulation of a response that now sets a precedent in both the health field and the maritime industry and tourism sector. This is because this operation demonstrates that a vessel in crisis cannot be treated as a “pariah,” but as a shared responsibility that requires prepared ports of refuge and rigorous international cooperation, as deployed in Tenerife with the support of the World Health Organization (WHO).

The identification of the Andes strain—the only variant of the virus capable of person-to-person transmission—raised the alert to the highest levels under the WHO International Health Regulations.

In this context, the response could not be individual. The management of the health crisis required precise coordination among various international and national bodies.

• The WHO, acting as a central information node, monitoring the trace of passengers who had disembarked at previous points and coordinating biological protocols.
• The European Union, activating the European Civil Protection Mechanism and coordinating, through the Emergency Response Coordination Centre, repatriation, logistical support, and joint response among Member States to an international health emergency.
• The Government of Spain, through External Health (Ministry of Health), with the support of other state operations such as Civil Protection, the Military Emergency Unit (UME), the National Police, and the Civil Guard, establishing safety criteria for anchoring, operational care, and border management.
• The Government of the Canary Islands, providing support and facilitating the technical, operational, and human logistics necessary to ensure the humanitarian assistance and health security required by an operation of this magnitude, thereby contributing to resolving this crisis without affecting the local population.

Thanks to this coordinated intervention, all efforts focused on preventing an outbreak confined to an expedition cruise from becoming an international public health emergency. This operation demonstrates that the health sovereignty of a country—in this case, Spain—can act hand in hand with international solidarity and repatriation processes, all under strict scientific oversight.

The international dimension of the case has turned the management of this crisis into an example of global health cooperation.

Tenerife as a Biosphere Certified Destination in the face of an international emergency.

Tenerife has demonstrated why it is a benchmark in sustainability and resilience as a tourist destination. By receiving the vessel at the Port of Granadilla, the island not only provided a port of refuge, but also actively collaborated in a highly precise operation aligned with the United Nations Sustainable Development Goals (SDGs).

The decision to manage passenger transit in a controlled manner, ensuring a “safe corridor” without risk to the local population or to tourists enjoying the island, highlights SDG 11 (Sustainable Cities and Communities) and SDG 3 (Good Health and Well-being).

Through this health crisis, Tenerife has demonstrated that being a top-level tourist destination also means being able to respond effectively to the unexpected, protecting both those who arrive on the island and those who live there.

In this context, being a sustainable destination goes far beyond a declaration of intent. It means being prepared to face health crises like this one, protecting public health and ensuring the safety of residents and visitors with responsibility, foresight, and efficiency. And that, precisely, is also sustainability.

One Health, sustainability, and global health in international tourism.

From Biosphere’s perspective, this crisis reinforces the One Health approach promoted by the WHO, which encourages the prevention and control of diseases—especially zoonoses (those transmitted from animals to humans)—as well as the fight against antimicrobial resistance and the guarantee of food safety.

This approach is based on the recognition that a very significant proportion of human infectious diseases originate in animals, and that ecosystem degradation and climate change directly affect public health. To address this reality, collaboration across multiple disciplines (medicine, veterinary science, research, etc.) at the local, national, and international levels is essential.

As successive health crises have shown, the interconnection between ecosystem health and human health is inseparable, especially when addressing zoonotic diseases such as hantavirus.

Expedition tourism, oriented toward connection with remote natural environments, must be accompanied by biosecurity protocols that ensure international mobility does not become a risk to public health.

In fact, the management of the hantavirus outbreak case aboard the MV Hondius in Tenerife also represents an example of how to activate SDG 17 (Partnerships for the Goals), because cooperation among international organizations, public administrations, and health authorities demonstrates that 21st-century sustainability requires strong, effective, and well-coordinated collaboration networks.

The island’s supportive response, far from being an isolated event, is the result of years of work in international cooperation networks and in strengthening critical infrastructure capable of responding to highly complex situations.

A human effort behind health management.

Beyond protocols and figures, it is essential to recognize the work of healthcare professionals, security forces, port personnel, and epidemiology experts involved in this health management in Tenerife.

For this reason, at Biosphere and the Responsible Tourism Institute (RTI), we wish to highlight the work of healthcare professionals, External Health (Ministry of Health), Civil Protection, the Military Emergency Unit (UME), the National Police, the Civil Guard, port personnel, epidemiology experts, and the technicians of the Canary Islands Government, as well as the coordinating role played by the WHO and the European Union. Likewise, we wish to express our gratitude to the diplomatic and consular staff of the countries involved, whose collaboration was essential in facilitating international coordination, assisting affected individuals, and carrying out repatriation processes.

Their work, often invisible, is what allows us today to speak of a contained crisis thanks to a joint, rigorous, and deeply human response.

Individualized care for passengers and crew, continuous health monitoring, and psychological support for those who experienced weeks of uncertainty reflect a model that places human dignity at its center.

Sustainability, in this context, is not only environmental. It is also social and health-related.

Prevention, learning, and strengthening international protocols.

As the resolution of this episode progresses, the objective has been twofold. On the one hand, to ensure that all those affected return to their countries of origin under safe conditions. On the other, to turn this experience into a strengthening of international health crisis management protocols.

The island of Tenerife, as a destination that is part of the international network of destinations holding the Biosphere Certified distinction, emerges strengthened from this situation. It has demonstrated that sustainability is not a static state, but a dynamic capacity to manage risks with ethics, science, and transparency.

This experience will remain as a lesson learned that will help improve preparedness for future health threats, reinforcing the idea that international cooperation is essential to ensuring safe and sustainable destinations.

We hope that the final steps of this operation conclude successfully and that this crisis can be considered resolved with the satisfaction of having acted under the values of solidarity, responsibility, and scientific rigor.

This episode reminds us that sustainability is not only about “being green,” but also about the ability to anticipate and rigorously manage the risks derived from our relationship with nature. Because, on an interconnected planet, the health of a passenger aboard a vessel in the South Atlantic ultimately becomes the health of us all.

Because a sustainable destination is, above all, a destination that cares for life.
