Scientists warn of a potential zombie virus, raising alarm for the next pandemic

The melting ice caps due to global warming have raised concerns among scientists about the release of ancient frozen viruses, including a potential “zombie virus,” which could lead to the next pandemic. This issue has gained attention because of the rising temperatures on Earth. Scientists fear that these viruses, preserved in the Arctic for 48,500 years, might pose a significant threat to global health, potentially surpassing the impact of COVID-19.

Geneticist Jean-Michel Claverie from Aix-Marseille University emphasized the oversight in current pandemic threat analyses, which predominantly focus on diseases emerging in southern regions and spreading north. Claverie warned that there is a real risk of an outbreak originating in the far north and traveling south, as viruses with the potential to infect humans might be lying dormant in the permafrost. This oversight could lead to underestimating the risks associated with these ancient viruses.

Marion Koopmans from the Erasmus Medical Centre in Rotterdam echoed Claverie’s concerns, emphasizing the lack of knowledge about the viruses present in the permafrost. Koopmans highlighted the possibility of an ancient virus, like a form of polio, being released and causing a new disease outbreak. The uncertainty surrounding the viruses in the permafrost emphasizes the need for preparedness and acknowledging the potential threats they pose to human health.

In 2014, a group of scientists conducted a study in Siberia, where they revived some of these “zombie viruses.” Despite being buried in permafrost for thousands of years, the live viruses showed the ability to infect single-celled creatures and cultured cells. While the virus experimented on in Siberia only infected amoebae and not humans, Claverie cautioned that this does not rule out the possibility of other viruses, currently frozen in the permafrost, being capable of triggering illnesses in humans. This experiment highlighted the potential resilience of these ancient viruses and their ability to remain infectious even after millennia of being frozen.

The revival of these ancient viruses raises concerns about their ability to adapt and infect humans, posing a threat similar to the current pandemic. The study in Siberia serves as a stark reminder that these viruses, despite their age, have the potential to cause diseases in modern humans. Understanding the risks associated with these viruses is crucial for developing strategies to prevent and mitigate the impact of potential outbreaks.

The urgency of addressing this issue is underscored by the fact that little attention has been given to outbreaks originating in the far north and spreading south. The focus on diseases moving from southern regions to the north has left a critical gap in our understanding of potential threats. Scientists emphasize the need to broaden our perspective and consider the possibility of outbreaks emerging from the Arctic, where these ancient viruses are preserved.
