Irish Examiner view: We must all be vigilant against avian flu

A warning sign for avian influenza (bird flu) in Barkby, Leicestershire.

We must hope that there is no serious westwards expansion of the latest instances of avian flu. It has been on the rise in Britain and has had a devastating impact in some seabird colonies.

While the risk to humans from the disease is low, its spread can lead to restrictions in poultry farms and to chickens and ducks experiencing their own forms of lockdown.
