Bird flu or influenza virus can live for years in frozen lakes, and might be picked up and carried by birds to reinfect animals and peoples, researchers revealed.
Such frozen viruses could potentially become the source of new epidemics that sicken and kill generations after they were last seen.
?We?ve found viral RNA in the ice in Siberia, and it?s along the major flight paths of migrating waterfowl,? said Dr Scott Rogers.
The lakes are along the migratory flight paths of birds flying into Asia, North America, Europe, and Africa.
