Italy Reports H5N1 Avian Influenza in Turkeys

10/25/2021

In a replay of previous avian influenza outbreaks, veterinary authorities have diagnosed highly pathogenic avian influenza strain H5N1 in a flock of 13,000 growing turkeys in the Province of Verona.  The outbreak was reported to the World Organization for Animal Health and appropriate quarantine and depopulation has been effected.

 

During 1999 and 2000, H7 strains of avian influenza were responsible for severe losses in Northern Italy. The extensive outbreak was eventually controlled by a combination of depopulation of affected flocks, restriction on movement of live birds. The outbreak was effectively eradicated by the application of inactivated vaccines using DIVA technology devised by Dr. Ilaria Capua, to differentiate among infected and vaccinated flocks.  Given recent advances in diagnosis including PCR, application of inactivated H5 and H7 vaccines using a DIVA approach is no longer necessary.
