Giant Virus Resurrected From Siberian Permafrost After 30,000 Years

Giant Virus Resurrected From Siberian Permafrost After 30,000 Years

A mysterious giant virus buried for 30,000 years in Siberian permafrost has been resurrected.

The virus only infects single-celled organisms and doesn’t closely resemble any known pathogens that harm humans.

Even so, the new discovery raises the possibility that as the climate warms and exploration expands in long-untouched regions of Siberia, humans could release ancient or eradicated viruses. These could include Neanderthal viruses or even smallpox viruses that have lain dormant in the ice for thousands of years.

“If they have been extinct for a long time, then our immune system is no longer prepared to respond to them.” study co-author Jean-Michel Claverie, a bioinformatics researcher at Aix-Marseille University in France, wrote in an email.
