Climate change is helping dangerous diseases spread across the Arctic. Scientists say rising temperatures are melting permafrost and damaging ecosystems. These changes open new paths for infections to move from animals to people.
An international research team published the findings in Science of the Total Environment. The study shows how warming is reshaping Arctic life. New roads, industries, and people now reach once-isolated areas. This raises the risk of infections like brucellosis, tularemia, and E. coli.
How is Climate Change Increasing Pathogenic Risk?
Researchers focused on Canada, Alaska, Greenland, and Northern Europe. They used a One Health approach, linking human, animal, and environmental health. The team studied past research and government records to find disease trends.
Permafrost thawing is a major concern. Frozen Arctic soil is melting due to global warming. This may release ancient microbes locked in the ice for thousands of years. The process also releases greenhouse gases, worsening climate change.
Zoonotic diseases, which jump from animals to humans, are the major concern. These include viruses, parasites, and bacteria that spread through water, food, or contact. Climate change and pollution are weakening the natural barriers that once kept these diseases contained.
Dr. Khaled Megahed Abass, a co-author from the University of Sharjah, called for global attention to this issue. He told Alaska Native News that Arctic risks affect the entire planet. “What happens in the Arctic doesn’t stay in the Arctic,” he warned.
What Do Researchers Say Can Mitigate Arctic Disease Risk?
The study recommends several actions to reduce Arctic disease risks. First, health policies must focus on tracking animal-to-human infections. Strategies should fit local needs and be culturally appropriate. Tourism policies should support health, safety, and sustainability.
Indigenous voices must help shape future Arctic policies. Local knowledge can improve planning and response. Arctic communities also need better access to healthcare and diagnostic tools
The team urges stronger disease monitoring. This includes bivalves, thawing lakes, and wastewater systems. These may hold signs of toxins or reawakening pathogens.
Vaccines and treatments must be developed and shared quickly. The study highlights the importance of public education on safe animal contact. Tourists, hunters, scientists, and locals all need proper guidance.
Healthcare workers need to learn how to spot Arctic-specific diseases. The study also recommends studying traditional food methods for disease prevention. Indigenous practices may offer protection and should be respected and researched.
Conclusion
The Arctic is warming fast, and disease risks are growing with it. Ancient pathogens, pollution, and weakened ecosystems threaten both local and global health. Experts say early action and One Health strategies can prevent future outbreaks.
