Bird flu, also known as avian influenza, is a viral infection that primarily affects birds but can also infect humans and other animals. The virus is categorized into various strains, with H5N1 and H7N9 being the most notorious for causing severe illness in humans. Bird flu outbreaks have been reported in various parts of the world, often leading to significant economic impacts due to the culling of infected poultry and trade restrictions. Understanding the nature of bird flu and its potential to cause pandemics is crucial for public health preparedness.

Bird flu is primarily spread through direct contact with infected birds or their secretions, such as saliva, nasal secretions, and feces. The virus can also be transmitted through contaminated surfaces or objects, such as bird cages or farm equipment. Human-to-human transmission is rare but can occur in close contact settings. Migratory birds play a significant role in spreading the virus across regions, making it challenging to control outbreaks. Proper biosecurity measures in poultry farms and markets are essential to prevent the spread of the virus.
