H5 Bird Flu

H5 Bird Flu refers to a subtype of the influenza A virus known as H5N1, which primarily affects birds but can also infect humans and other animals. The term “H5” indicates the specific hemagglutinin antigen on the virus’s surface, which is crucial for the virus’s ability to infect host cells. H5N1 is notable for its high mortality rate in humans who become infected, although human cases are rare. The virus is primarily spread among bird populations, particularly domestic poultry, and can lead to severe respiratory illness in infected birds. Outbreaks of H5 Bird Flu in avian populations can pose significant threats to agriculture and public health. The term encompasses various strains under the H5 classification, particularly those associated with outbreaks and zoonotic transmission to humans.
