Ancient viruses - not seen anywhere in the world for centuries - are at risk of wiping people out due to climate change, scientists say.
Particles of the illnesses remain infectious even today in mammoth wool, Siberian mummies, prehistoric wolves and even the lungs of an Influenza victim buried in frozen ground, the researchers have found.
Institutions in Russia, Germany and France worked together in the new study, which has found "the risk is bound to increase in the context of global warming , in which permafrost thawing will keep accelerating", unleashing some diseases which had been trapped in the ice since prehistoric times.
