The biggest virus in the world caught in the ice since 30,000 was awakened!

The biggest virus in the world caught in the ice since 30,000 was awakened!

Warming promotes the return to life of pathogens against which man is no longer immune. A virus more than 30,000 years old has been found in the frozen soils of the extreme northeastern Siberia. This corresponds to the Upper Pleistocene, the time of extinction of Neanderthal man. If Pithovirus sibericum infects amoebae, it is harmless toHumans and animals, recall the researchers.

"But the very fact that a virus of 30,000 years can be brought back to life means that pathogens for humans can also resurface in the same way," says Chantal Abergel, director of research at the CNRS and co-author of the publication "The danger is real," insists Jean-Michel Claverie.

Ice melting in the Arctic and permafrost (the layer of land that is permanently frozen) will make accessible areas that were not previously frozen."By digging for oil or gas, men may unintentionally come into contact with germs."

The danger does not come from the surface layer alone. The Arctic is considered a new mining eldorado. "By digging for oil or gas, men may unintentionally come into contact with germs. Even if they are only a few in a desert zone, they may become contaminated and above all become vectors, "insists the researchers. Especially since these areas of the Far North were inhabited a few thousand years ago. Once pathogens can be released again during these industrial surveys, the risk of contamination becomes high, knowing that immune defenses do not exist or have disappeared for years.

A new protozoan parasite previously sequestered under ice has also recently emerged, causing extensive mortality in gray seals and other threatened Arctic mammals. An episode reported by researchers in February in Chicago at the annual symposium of the American Society for the Advancement of Science (AAAS). They stated that the parasite had affected sea lions, walruses, polar bears and grizzlies all the way to southern British Columbia (Canada).

We have seen in the past the disasters that could be caused in humans by pathogens that did not exist in their environment. This was the case with the Indians decimated by measles and syphilis contracted with Europeans. More recently, we know the disaster caused by the AIDS virus when it passed from monkey to man. "If the man from Neanderthal has been affected by an infection, drilling could revive this disease," warns Chantal Abergel. Scientists also have in mind the smallpox virus, whose replication process is similar to that of Pithoviruses. "It is believed to have eradicated smallpox, but this is the case only on the surface of the Earth," continues the scientist.
