Branswell: Spread of avian flu confounds scientists

Helen Branswell reports that an avian equivalent of a stealth bomber may be on its way: a bird that carries H5N1 without showing symptoms. Her story is in The Globe and Mail.

“If this is a . . . virus that seems to have fixed itself in some species and we don't know which species it is — but maybe it's not showing any clinical sign in this particular species — how do we find this guy?” Michael Perdue, avian influenza expert with the World Health Organization, asks with evident anxiety in his voice.

The realization that some mystery migratory birds are actually spreading the Asian virus suggests future unwanted appearances in Europe cannot be ruled out.
