     ATLANTA (AP) -- For the first time, scientists have
evidence of flu in bats.  U.S. health officials say they found
genetic fragments of a never-before-seen virus in some
Guatemalan bats.  Flu bugs are common in humans, birds, pigs and
a variety of other animals, but this is the first time one has
been documented in these winged mammals.  So far, scientists
haven't been able to grow it, and it's not clear if -- or how
well -- it spreads. The risk to humans also is unclear.  The
Centers for Disease Control and Prevention did the study. The
research was posted online Monday in the journal Proceedings of
the National Academy of Sciences.
