👉 H15N9 is a highly pathogenic strain of avian influenza virus that causes severe respiratory illness and death in poultry, primarily affecting hens. It was first identified in 2016 and has since spread to poultry farms worldwide, leading to widespread outbreaks. The H15N9 strain has been linked to the H7N9 pandemic in chickens, which occurred from 2013 to 2018.
