Zombie Viruses: The world is still reeling from the devastating effects of the COVID-19 pandemic, which has claimed millions of lives and disrupted the global economy and society. However, scientists warn that another pandemic could strike the world from an unexpected source: the melting Arctic permafrost. This frozen layer of soil and organic matter, which covers about a quarter of the northern hemisphere, could harbor ancient viruses that have been dormant for thousands or even millions of years. These viruses, dubbed “zombie viruses” or “Methuselah microbes”, could potentially infect humans and animals, and cause new and unknown diseases. In this article, we will explore the characteristics, origins, and implications of these Arctic zombie viruses, and why they pose a significant and emerging threat to global health and security.

Characteristics of Arctic Environments

The Arctic is a vast and diverse region that encompasses the northernmost parts of North America, Europe, and Asia, as well as the Arctic Ocean and its surrounding seas and islands. The Arctic is home to about four million people, who belong to various indigenous and non-indigenous cultures and communities. The Arctic is also rich in natural resources, such as oil, gas, minerals, fish, and wildlife, and plays a key role in regulating the global climate and environment.

One of the defining features of the Arctic is the permafrost, which is the soil or underwater sediment that has been frozen for at least two consecutive years. Permafrost can vary in thickness, from a few centimeters to several meters, and can extend up to 1,500 meters below the surface. Permafrost can also contain large amounts of organic matter, such as plants, animals, and microbes, that have been preserved by the cold and dark conditions. Permafrost can store up to twice as much carbon as the atmosphere and can act as a natural freezer that keeps biological material intact for long periods of time.

Historical Perspective

The idea that permafrost could contain ancient viruses that could infect humans and animals is not new. In fact, there have been several instances in history where viruses have been recovered or revived from permafrost or other frozen environments, and have caused outbreaks or epidemics. Some of the notable examples are:

• In 1918, the Spanish flu pandemic killed about 50 million people worldwide and was caused by an H1N1 influenza virus that originated from birds. In 1997, scientists extracted and sequenced the virus from the lungs of a victim who was buried in the Alaskan permafrost. In 2005, scientists recreated and tested the virus in a laboratory, and found that it was highly lethal and contagious.
• In 1979, an anthrax outbreak killed 64 people and infected more than 100 others in the Sverdlovsk region of Russia. The outbreak was caused by a leak of anthrax spores from a military facility that was testing biological weapons. The spores were derived from a strain of anthrax that was isolated from a reindeer that died in 1941 and was buried in the Siberian permafrost.
• In 2016, a 12-year-old boy died and 20 others were hospitalized after contracting anthrax in the Yamal Peninsula of Russia. The outbreak was caused by the thawing of a reindeer carcass that was infected with anthrax and buried in the permafrost for 75 years. The carcass was exposed by an unusually warm summer that melted the permafrost and released the spores into the air and water.

These cases illustrate the potential dangers of viruses that are buried in the permafrost and can be released by natural or human-induced factors. They also highlight the importance of monitoring and containing the outbreaks, and of developing and deploying effective vaccines and treatments.

Potential Origins of Arctic Zombie Viruses

The origin and nature of the viruses that could be lurking in the permafrost are still unknown and uncertain. However, there are two main hypotheses that have been proposed by scientists: natural evolution and adaptation, and ancient viruses released due to climate change.

Natural evolution and adaptation

One hypothesis is that the viruses that could be found in the permafrost are the result of natural evolution and adaptation of existing viruses that have been circulating in the Arctic environment for a long time. These viruses could have adapted to the cold and harsh conditions of the permafrost and could have developed unique and novel features that make them different from their counterparts in other regions. These viruses could also have co-evolved with their hosts, such as animals, plants, and microbes, and could have established a balance or symbiosis with them. These viruses could pose a threat to humans and animals if they are exposed to new and unfamiliar hosts, and if they have the ability to cross species barriers and cause infection and disease.

Ancient viruses released due to climate change

Another hypothesis is that the viruses that could be found in the permafrost are ancient viruses that have been frozen and dormant for thousands or even millions of years, and that are being released due to climate change. These viruses could have originated from various sources, such as prehistoric animals, plants, and microbes, or from human civilizations and activities, such as burials, wars, and migrations. These viruses could have been trapped and preserved in the permafrost and could have survived the freezing and thawing cycles without losing their infectivity and virulence. These viruses could pose a threat to humans and animals if they are revived and reactivated by the warming and melting of the permafrost, and if they have the potential to infect and cause disease in modern hosts.

Risks and Challenges

The discovery and emergence of Arctic zombie viruses pose several risks and challenges for the world, as they could potentially spread and cause new and unknown diseases in humans and animals. The risks and challenges include:

Spread of Arctic zombie viruses

One of the main risks of Arctic zombie viruses is their ability to spread and infect new hosts, especially if they are released from the permafrost due to climate change or human activities. The spread of Arctic zombie viruses could occur through various routes, such as:

• Airborne transmission: Some viruses, such as influenza and anthrax, can be carried by air currents and inhaled by humans and animals, causing respiratory infections and diseases.
• Waterborne transmission: Some viruses, such as hepatitis and norovirus, can contaminate water sources and cause gastrointestinal infections and diseases.
• Vector-borne transmission: Some viruses, such as dengue and Zika, can be transmitted by insects or animals that bite or feed on humans and animals, causing systemic infections and diseases.
• Zoonotic transmission: Some viruses, such as rabies and Ebola, can be transmitted from animals to humans through direct or indirect contact, causing neurological or hemorrhagic infections and diseases.

The spread of Arctic zombie viruses could be facilitated by several factors, such as:

• Globalization and mobility: The increased movement and travel of people, goods, and animals across the world could facilitate the introduction and dissemination of Arctic zombie viruses to new regions and populations.
• Climate change and environmental degradation: The rising temperatures and melting ice could increase the exposure and release of Arctic zombie viruses from the permafrost, and also alter the habitats and behaviors of potential hosts and vectors.
• Lack of immunity and surveillance: The lack of natural or acquired immunity against Arctic zombie viruses among humans and animals could increase the susceptibility and severity of infections and diseases, and the lack of adequate surveillance and monitoring systems could delay the detection and response to outbreaks.

Impact on local wildlife and ecosystems

Another risk of Arctic zombie viruses is their impact on the local wildlife and ecosystems, which are already threatened by climate change and human activities. The impact of Arctic zombie viruses could include:

• Loss of biodiversity and ecosystem services: The infection and mortality of wildlife species due to Arctic zombie viruses could reduce the diversity and abundance of flora and fauna, and affect the ecological functions and processes that they provide, such as pollination, predation, and decomposition.
• Disruption of food webs and trophic cascades: The infection and mortality of wildlife species due to Arctic zombie viruses could alter the interactions and balances among different trophic levels, and cause cascading effects on the structure and function of the food webs.
• Emergence of invasive and opportunistic species: The infection and mortality of wildlife species due to Arctic zombie viruses could create vacant niches and opportunities for the invasion and proliferation of non-native or opportunistic species, which could compete with or prey on the native species, and introduce new pathogens or parasites.

Potential for human transmission

A third risk of Arctic zombie viruses is their potential for human transmission, which could cause new and unknown diseases in humans. The potential for human transmission could depend on several factors, such as:

• Viral characteristics: The genetic and molecular features of Arctic zombie viruses, such as their origin, evolution, adaptation, and diversity, could determine their ability to infect and cause disease in humans, and their susceptibility or resistance to existing drugs and vaccines.
• Host factors: The genetic and immunological features of humans, such as their age, sex, ethnicity, and health status, could influence their vulnerability and response to Arctic zombie viruses, and their potential to transmit them to others.
• Environmental factors: The physical and social features of the environment, such as the climate, geography, population density, and sanitation, could affect the exposure and transmission of Arctic zombie viruses among humans, and the availability and accessibility of health care and prevention services.

Scientific Research and Monitoring

The exploration and investigation of Arctic zombie viruses are essential for understanding their origin, nature, and implications, and for developing and implementing effective measures to prevent and control their spread and impact.
