Introduction to Avian Influenza A Virus (AI) The Avian Influenza A Virus (AIV), often simply termed Bird Flu, represents a diverse group of RNA viruses belonging to the family Orthomyxoviridae. These viruses are characterized by their segmented, negative-sense single-stranded RNA genome, which facilitates rapid evolution through reassortment, a critical mechanism driving the emergence of novel […]
Introduction: The Context of Avian Influenza and Human Behavior Avian Influenza (AI), particularly highly pathogenic strains such as H5N1 and H7N9, represents a persistent and significant global public health challenge due to its zoonotic potential—the ability to transmit from birds to humans. While human-to-human transmission has historically been limited or inefficient for these strains, the […]
Definition and Classification of Avian Influenza Viruses Avian Influenza (AI) refers to diseases caused by infection with Type A influenza viruses that naturally circulate among wild aquatic birds worldwide. These viruses belong to the family Orthomyxoviridae, possessing a segmented, single-stranded RNA genome enveloped by a lipid bilayer. The classification and nomenclature of these viruses are […]
