Arctic Animal-Borne Infection Guidance Released for Clinicians Amid Climate Change Risks

Understanding Zoonotic Infections in the Canadian Arctic: A Clinician’s Perspective

As the canadian Arctic gains global attention, the region is also facing significant challenges due to climate change. These environmental shifts are not only reshaping the landscape but also increasing the risk of zoonotic infections—diseases that spread from animals to humans. A recent review offers valuable insights for healthcare professionals on identifying and managing these infections, ensuring the well-being of Arctic communities.

dr. Justin Penner, an infectious diseases physician, along with his co-authors, highlights the deep connection Indigenous Peoples have with the Arctic surroundings. “Indigenous peoples continue to be caretakers of the Canadian Arctic; their cultural connection with the Arctic environment and ecosystem generates unique exposures to the zoonotic diseases discussed, and also others not covered here,” they note. This relationship underscores the importance of integrating conventional practices into modern healthcare approaches.

The Canadian Arctic encompasses three distinct bioclimates—subarctic, low Arctic, and high Arctic—and is home to diverse Indigenous communities, including the Inuit, Gwich’in, and Athabaskan peoples. The authors advocate for a holistic approach to clinical care, combining Inuit Qaujimajatuqangit, or Inuit Traditional Knowledge, with the One Health principle. This principle emphasizes the interconnectedness of human, animal, and environmental health.

“Cultural proximity and interaction with the Arctic ecosystem are critically significant factors in understanding some of the under-recognized infectious diseases within the region. Clinicians’ respect and understanding of these customs can highlight infectious exposures, guide clinical care, and inform prevention programs,” the authors explain. This approach is essential for addressing the unique challenges posed by zoonotic infections in the Arctic.

Key risk factors include diets rich in “country foods”—wild game, fish, and sea mammals—which are staples in many Arctic communities. Activities such as hunting, animal harvesting, and preparing animal skins, as well as owning sled dogs, also increase exposure to animal-borne diseases.

Climate change is profoundly impacting the Arctic ecosystem. “Animal behavior is changing,including migration patterns,largely as a result of diminishing sea ice,which limits hunting. these factors can affect parasite life cycles. Melting permafrost has an impact on how food is processed, making practices like fermentation and ice-cellar storage less reliable. Warmer temperatures also promote the spread of insect vectors into higher latitudes, which will further affect Arctic ecosystems and cause the emergence of other infections in the region where populations are vulnerable,” the authors write.

This review serves as a critical resource for clinicians, offering guidance on managing zoonotic infections while respecting the cultural and environmental context of the Canadian Arctic. As the region faces the dual pressures of climate change and global interest, such insights are essential for safeguarding the health of itS communities.

Dr. Emily Carter,a leading expert in zoonotic diseases,recently shed light on this pressing issue,emphasizing the critical role of climate change and the need for a collaborative approach to address it.

What Are Zoonotic Infections?

Zoonotic infections are diseases transmitted from animals to humans through bacteria, viruses, parasites, or fungi. In the Arctic,these infections are particularly worrisome due to the region’s fragile ecosystem and the accelerating effects of climate change. As Dr. Carter explains, “Warmer temperatures are causing permafrost to thaw, which can release pathogens that have been dormant for centuries.” This, combined with shifting animal migration patterns and increased human activity, creates a perfect storm for disease transmission.

Climate change: A Catalyst for Disease Spread

Climate change is a significant driver of the rising threat of zoonotic infections in the Arctic. Thawing permafrost not only releases ancient pathogens but also alters the behavior of wildlife. For instance, Arctic foxes are moving further north, coming into contact with new animal populations and potentially spreading diseases like rabies or tularemia. “Changes in wildlife behavior create new opportunities for disease transmission,” Dr. Carter notes, highlighting the interconnectedness of environmental and human health.

Challenges in Diagnosis and Treatment

diagnosing and treating zoonotic infections in the Arctic presents unique challenges. Many remote communities lack the necessary healthcare infrastructure and resources. clinicians frequently enough face difficulties due to limited access to diagnostic tools and specialized expertise. “The symptoms of zoonotic infections can mimic other common illnesses, making accurate diagnosis tough,” Dr. Carter explains.For example, brucellosis, a bacterial infection transmitted from caribou, often presents with flu-like symptoms, leading to potential misdiagnosis.

Preparing for the Future

To better address these challenges, dr. Carter emphasizes the importance of education, awareness, and collaboration. “Clinicians need to be trained to recognize the signs of zoonotic infections and understand the local wildlife and environmental factors that contribute to disease transmission,” she says. Additionally, integrating Indigenous knowledge can provide valuable insights into animal behavior and disease patterns. Improving healthcare infrastructure and access to diagnostic tools will also be crucial in managing these infections effectively.

The One Health Approach

Dr. Carter advocates for a One Health approach, which recognizes the interconnectedness of human, animal, and environmental health. “In the context of the Arctic, this means collaboration between medical professionals, veterinarians, ecologists, and policymakers,” she explains. By adopting this holistic strategy,stakeholders can better understand and mitigate the risks posed by zoonotic diseases.

Looking Ahead

As the Arctic continues to warm,the threat of zoonotic infections will likely grow. Dr. Carter identifies several priorities for the future: “First, we need more research to understand the full scope of zoonotic risks in the Arctic. Second,we must strengthen healthcare infrastructure and ensure that remote communities have access to the resources they need.” By addressing these challenges proactively, we can better protect both human and animal populations in this vulnerable region.
