Can flu viruses survive winter in frozen lakes?

Evidence of flu viruses frozen in Siberian lakes has prompted researchers to examine the possibility that global warming may release microbes locked in glaciers for decades or even centuries.

"Our hypothesis is that influenza can survive in ice over the winter and re-infect birds as they come back in spring," says Scott Rogers of Bowling Green State University, Ohio, US. He believes the frozen lakes act as "melting pots" for flu viruses, allowing viruses from one year to mix with those from previous years.
