avian influenza (bird flu)

Avian influenza, or bird flu, is a viral infection that affects birds, especially poultry. It is caused by influenza A viruses and can spread rapidly among bird populations. Some strains are highly contagious and can lead to severe illness or death in birds. While most bird flu viruses do not infect humans, certain strains can cross the species barrier and cause illness in people, sometimes with serious outcomes. The virus can spread through contact with infected birds, contaminated equipment, or environments. Managing bird flu involves monitoring bird populations, culling infected flocks, and enforcing biosecurity measures to prevent outbreaks.
