Recently， a team of French scientists firstly found a kind of giant virus 30000 years ago in Siberia of Russia， and woke up the virus’ activity successfully. As the virus looks exactly like the stean of ancient Greek， the scientists called this virus “Pithovirus sibericum”. The virus is the third giant virus has been found. It’s 1.5 microns in length and 0.5 microns in width， which could be directly observed by optical microscope. The team member who found and researched this virus says that the new virus has very simple genome but complex self replication mode， and it still has infectivity today. He also reminds that though this virus won’t threat human security for the moment， the ice sheet melting caused by global warming may recover the activity of the virus under frozen earth， and pose a risk to human health.
