Move over bird flu, bat flu is next

If a bird flu outbreak in Indonesia weren't enough, scientists have now found a new influenza virus that infects bats. The new virus belongs to a family of flu viruses called Influenza A. Birds are natural hosts for these viruses, but they are found in other animals, too, including pigs, horses, seals and whales. So far, there is no evidence the newly discovered virus is causing illness among the bats.
