Silent spread no more: Discover how advanced surveillance methods are safeguarding vaccinated duck flocks from avian influenza outbreaks.
In a recent article in the journal Emerging Infectious Diseases, researchers utilized mathematical models to evaluate the effectiveness of strategies to detect highly pathogenic avian influenza (HPAI) among flocks of vaccinated ducks in France.
Their results indicate that enhanced passive surveillance by testing dead birds weekly was the most effective surveillance method, while monthly testing of live birds emerged as the least effective method.
Background
HPAI viruses have caused significant disease outbreaks globally, particularly since 2016, when HPAI clade 2.3.4.4b emerged. These viruses primarily affect birds, posing a major challenge for the poultry industry through direct losses from high illness and fatality...
