Avian flu virus found among penguins in Antarctica

An international team of researchers have for the first time identified a new avian influenza virus in a group of Adelie penguins from Antarctica. The virus is unlike any other circulating avian flu viruses. While other research groups have taken blood samples from penguins before and detected influenza antibodies, no one had detected actual live influenza virus in penguins or other birds in Antarctica previously, said senior research scientist Aeron Hurt at the WHO Collaborating Centre for Reference and Research on Influenza in Melbourne, Australia. The virus did not cause illness in the penguins but the study shows that avian influenza viruses can get down to Antarctica and be maintained in penguin populations, he said. “It raises a lot of unanswered questions,” Hurt added. They include how often Avian Influenza Virus (AIVs) are being introduced into Antarctica, whether it is possible for highly pathogenic AIVs to be transferred there, what animals or ecosystems...
