Bird flu studies, halted over terrorism fear, to resume

LONDON, Jan 24: Scientists around the world declared an end yesterday to a moratorium on researching mutant forms of the deadly H5N1 bird flu that had raised international biosecurity concerns. Announcing their decision to resume what they say are risky but essential studies of the avian flu strain, the scientists said the work would only be carried out in the most secure sites in countries that agree it can go ahead.
