Bird flu (avian influenza) primarily affects birds but can also infect humans, with the most dangerous strains being H5N1 and H7N9. Outbreaks often result in significant economic losses due to poultry culling and trade restrictions. The virus spreads through direct contact with infected birds or contaminated surfaces. While human-to-human transmission is rare, close contact can increase the risk, and migratory birds help spread the virus globally.

Strict biosecurity measures in poultry farms and live bird markets are crucial for preventing its spread. Early detection is essential for limiting its impact, allowing for timely medical intervention and the implementation of control measures. Raising awareness of early symptoms is particularly important for high-risk groups, such as poultry workers and those in close contact with birds.
