Target Species


Highly Pathogenic Avian Influenza in Poultry

Highly pathogenic avian influenza (HPAI) is an extremely contagious, multi-organ systemic disease of poultry leading to high mortality in poultry.1 The disease is caused by some H5 and H7 subtypes of type A influenza virus, family Orthomyxoviridae.1 These HPAI viruses can develop from certain LPAI viruses, usually while they are circulating in poultry flocks.2

HPAI viruses can kill up to 90-100% of the flock, and cause epidemics that may spread rapidly, devastate the poultry industry and result in severe trade restrictions.2

Vaccination has become the primary control measure used to minimize losses.3
