n# Rising Zoonotic Infections in the Arctic: A Hidden Health Crisis Amid Climate Change
The Arctic, a region often overlooked in global health discussions, is facing a growing threat: the rise of zoonotic infections.these diseases, which jump from animals to humans, are becoming increasingly concerning due to the region’s rapidly changing surroundings.Dr. Justin Penner, an infectious disease specialist at the Children’s hospital of eastern Ontario and Qikiqtani General Hospital in Iqaluit, Nunavut, emphasizes the urgency of this issue. “It’s a combination of diseases that don’t get a lot of attention to begin with, in a region that doesn’t get a lot of attention,” he explains.
The Silent spread of Zoonotic Diseases

Zoonotic infections in the Arctic are often under-detected and under-reported, making it difficult to gauge their true incidence.“I don’t think it’s likely that it (zoonotic infection) would spread like COVID, but it could certainly go unnoticed,” Dr. Penner warns. The lack of awareness among clinicians further complicates the issue, as many are unfamiliar with these diseases.
Risk factors for these infections include customary practices such as hunting, harvesting animals, and preparing animal skins. Even owning sled dogs can increase the risk of contracting animal-borne diseases. Traditional foods like game, fish, and marine mammals, while integral to the healthy diet of Arctic communities, also pose a risk.
Climate Change: A Catalyst for Disease
The Arctic is warming at an alarming rate, and this is having profound effects on the local ecosystem. Animal behavior is changing, with migration patterns shifting due to diminishing sea ice.These changes disrupt the life cycles of parasites, increasing the risk of zoonotic infections. “The environment is changing and that includes the environment in the North, and probably it’s changing more rapidly then other areas of the arctic,” Dr. Penner notes. “It greatly disrupts the ecosystem and has an impact on the spread of diseases.”
Melting permafrost is another critical factor.It affects food processing, making traditional practices like fermentation and storage in ice cellars less reliable. Warmer temperatures also encourage the spread of insect vectors to higher latitudes, further threatening arctic ecosystems and introducing new infections to vulnerable populations.
The ‘One Health’ Approach
Dr. Penner highlights the importance of the ‘One Health’ concept, which recognizes the interconnectedness of human, animal, and environmental health. “Humans and animals are interacting more and more closely, and this will certainly cause or facilitate the transmission of diseases,” he explains. Clinicians working in the Arctic must understand the indigenous cultures of the communities they serve to identify unique exposure risks and provide better clinical care.
Key Takeaways

| Risk Factors | Traditional foods, hunting, harvesting animals, owning sled dogs |
| Climate impact | Melting permafrost, changing animal behavior, spread of insect vectors |
| Clinical Awareness | under-detected and under-reported infections, need for clinician education |
| ‘One Health’ Approach | Interconnectedness of human, animal, and environmental health |
The Arctic’s unique challenges require a tailored approach to healthcare. As Dr. Penner and his colleagues emphasize, understanding the region’s specific risks and cultural practices is essential for combating the rise of zoonotic infections. The time to act is now, before these hidden threats become a larger crisis.
The Arctic, a region frequently enough overlooked in global health discussions, is facing a growing threat: the rise of zoonotic infections. These diseases, which jump from animals to humans, are becoming increasingly concerning due to the region’s rapidly changing habitat. To shed light on this critical issue, we spoke with Dr. Justin Penner, an infectious disease specialist at the Children’s Hospital of Eastern Ontario and Qikiqtani General Hospital in Iqaluit, Nunavut.
The Silent Spread of Zoonotic Diseases
Editor: Dr. Penner, could you explain why zoonotic infections in the Arctic are so concerning and often go unnoticed?
Dr. Penner: Absolutely. Zoonotic infections in the Arctic are frequently enough under-detected and under-reported, making it difficult to gauge their true incidence. Many clinicians in the region aren’t familiar with these diseases, which complicates diagnosis and treatment. While I don’t think these infections would spread like COVID-19, they could certainly go unnoticed, creating a hidden health crisis.
Risk Factors in Arctic Communities
Editor: What are some of the key risk factors that make Arctic communities especially vulnerable to these infections?
Dr.Penner: Traditional practices like hunting, harvesting animals, and preparing animal skins are significant risk factors. Even owning sled dogs can increase exposure to animal-borne diseases. Additionally,traditional foods such as game,fish,and marine mammals,while integral to the healthy diet of Arctic communities,also pose a risk.These practices are deeply rooted in the culture, so it’s a delicate balance to address the risks while respecting traditions.
Climate Change: A Catalyst for Disease
Editor: How is climate change impacting the spread of zoonotic infections in the Arctic?
Dr. Penner: The Arctic is warming at an alarming rate, and this is profoundly affecting the local ecosystem. Animal behavior is changing, with migration patterns shifting due to diminishing sea ice. These changes disrupt the life cycles of parasites, increasing the risk of zoonotic infections. Additionally, melting permafrost is affecting food processing, making traditional practices like fermentation and storage in ice cellars less reliable. Warmer temperatures also encourage the spread of insect vectors to higher latitudes, introducing new infections to vulnerable populations.
The ‘One Health’ Approach
Editor: can you explain the ‘One health’ approach and why it’s crucial for addressing this issue?
Dr. Penner: The ‘One Health’ concept recognizes the interconnectedness of human, animal, and environmental health. As humans and animals interact more closely, the transmission of diseases becomes more likely. Clinicians working in the Arctic must understand the indigenous cultures of the communities they serve to identify unique exposure risks and provide better clinical care.this holistic approach is essential for combating the rise of zoonotic infections.
